           The sludge of urban sewage treatment plant is the primary means in the process of waste water treatment sedimentation tank sludge, sludge and two mixed sludge, but this does not include the gate slag grid was blocked the flotation tank scum and grit sand. Because of toxic and harmful substances in the sludge containing high content. The two environmental pollution caused by direct contact with the environment will offset the sludge, sewage treatment and environmental benefits and social benefits. According to the relevant data show that in 2011, the sewage treatment capacity in Guangdong province reached 19 million 880 thousand tons / day, every day the number of sludge more than 8000 tons (with water content 80%) sludge also contains. Higher N, P and other nutrients, can achieve through the land use of sludge two times using. Therefore, sludge is a resource and pollution of the dual nature. At present, the disposal and should realize the stabilization, reduction, harmless and Resources, sludge disposal way is mainly sanitary landfill, composting land utilization, incineration and comprehensive utilization. Guangdong Province of sludge treatment and disposal is mainly to landfill and land use mainly, the sludge is transported to landfill landfill disposal accounted for half of the total amount of the waste, one-third of the sludge was preparing nutrition soil, composting and land use, the rest of the sludge is used for bio fuel and the production of building materials. In order to ensure the effective solutions to the problems of processing sludge treatment, Guangdong Province developed a variety of policies, auxiliary sludge treatment and disposal of the work of development.
           Technical policy
             In February 2009, the Ministry of construction, Ministry of environmental protection, Ministry of science and technology jointly issued < urban sewage treatment plant sludge treatment and disposal technology policy (for Trial Implementation) > (hereinafter referred to as < policy >) put forward that sludge treatment disposal reduction at the source and principle to control the whole process, specifically elaborated the circumstances under which should be adopted in the sludge treatment process, and for the corresponding provisions, comprehensive system to pointed out all kinds of sludge outlet, clear the sludge treatment and disposal of safeguard measures.
          In March 2010, the Ministry of environmental protection issued < urban sewage treatment plant sludge treatment and disposal of best available technologies of pollution prevention and control guide (Trial) > (hj-bat-002), for the municipal waste water treatment plant sludge processing disposal project environmental impact assessment, engineering design, project acceptance and operation management and link provides technical basis.
            In March 2011, the Ministry of construction and the national development and Reform Commission issued < urban sewage treatment plant sludge treatment and disposal technology guidelines (for Trial Implementation) >, summarizes the in recent years, China's urban sewage treatment plant sludge treatment and disposal of practical experience and research results, drawing on the advanced experience at home and abroad, in the sludge disposal technology route and scheme selection of MIT, unit technology of sludge treatment and sludge disposal methods and related technology, emergency response and risk management are guidelines make. 
          Normative documents
          The Ministry of environmental protection "Circular on strengthening the" urban sewage treatment plant sludge pollution prevention and control work in Guangdong province and the "on the further strengthening of the province's urban sewage treatment plant sludge disposal opinions documents issued, display disposal harmless sludge has been emphasized. Documents clearly deal with the sewage treatment plant sewage generated in the process of sludge (including primary sludge, sludge and mixed sludge disposal) bear the responsibility of the legal representative or the main person in charge is the first responsibility of sludge pollution prevention. Encourage in safety, environmental protection and economy under the premise, the recovery and utilization of sludge in energy and resources. For the storage of sewage treatment plant (i.e. not for the purpose of sludge disposal) will be out of factory, must be sludge dehydration to moisture content below 50%.
           In February 2009, the Ministry of construction, Ministry of environmental protection, Ministry of science and technology jointly issued < urban sewage treatment plant sludge treatment and disposal technology policy (for Trial Implementation) >, clear of the local people's government is sludge treatment and disposal facilities planning and construction of the main responsibility, this point in the < advice > also made prominent stressed.
          In 2009, the Guangdong provincial government issued < Guangdong Province strict control of waste processing for the implementation of administrative licensing way >, urban sewage treatment plant sludge column for strict control of waste management, the requirements in sludge disposal activities of enterprises to deal with, must to the provincial environmental protection department to apply for strict control of waste disposal permit.
          Expense policy for sludge disposal  
              Policy issued in 2009 the sewage treatment fee should include the sludge treatment and disposal of operating costs. The first article "the local people's government should further improve the sewage treatment fee collection efforts and management level of sewage treatment fee should include the sludge treatment and disposal costs; through the sewage treatment fee, financial subsidies and other ways to implement the sludge treatment and disposal the cost of sludge treatment and disposal facilities, to ensure the normal and stable operation of" second regulations "at all levels of government should increase the construction of sludge treatment and disposal facilities for capital investment, for the inclusion of the country to encourage the development of sludge treatment and disposal technology and equipment, to give financial and tax incentives according to regulations; to establish a diversified investment and operation mechanism, encourage through franchising in many ways, to guide social capital to participate in the construction and operation of sludge disposal facilities"
             2011 Guangdong Provincial Price Bureau and the environmental protection department < on our province strict control sludge disposal price management notice > treatment for sludge treatment and disposal price management guidance. Sludge treatment disposal price by the sludge dehydration depth, collection, transportation, storage, treatment and final disposal of reasonable cost, profit, taxes constitute, proposed by the sludge disposal enterprise, the local prefecture level based on the listing price in consultation with the competent department of environmental protection at the same level department in charge of audit submitted to the provincial Price Bureau approval.
           Standards and technical regulation
             At present our country still adopts the standard sludge control standard of pollutants in agricultural sludge (gb4284-84), and in 2002 promulgated the "urban sewage treatment plant pollutant discharge standard" (Gb189182002), which to our country sludge pollution control limited role. In recent years, successively awarded "the town sewage treatment plant sludge (mud > GB 24188-2009), < classification > sludge disposal of urban sewage treatment plant" (gb/t23484-2009), sludge disposal landfill mud > urban sewage treatment (gb/t23485-2009), urban sewage treatment plant sludge disposal landscape with mud (gb/ < t23486-2009), with mud > land improvement of sludge treatment of waste water treatment plant (gb/t 24600-2009), "urban sewage treatment plant sludge disposal for separate incineration mud (gb/t 24602-2009), < > > with mud brick of sludge treatment of waste water treatment plant (gb/t 25031-2010), a positive role in regulating the market sludge.
          In addition, the Ministry of construction formulated and issued the sludge industry standards, such as: < urban sewage processing plant sludge mud > cj247-2007, < urban sewage treatment plant sludge disposal landscape with mud > (cj248-2007) < urban sewage treatment plant sludge disposal mixed landfill clay > cj/t249-2007 < of urban sewage treatment plant sludge disposal in separate incineration with mud > (cj/t290-2008) basically solve lack of supervision of sludge disposal and resource products application security of problem.
           Sludge treatment and sludge disposal is a difficult problem facing the city, countermeasure of industry experts and environmental companies are seeking to solve the problem of sludge treatment and disposal. At present, Zhengzhou TEDA energy-saving drying equipment Technology Co. Ltd. in Anhui Wuhu's local government attaches importance to sludge disposal project, Zhengzhou TEDA energy-saving drying equipment Co. Ltd. with the project, sent a senior project engineer to inspect, and come up with practical solutions to the completion of the Anhui Wuhu sludge treatment project. Zhengzhou TEDA energy-saving drying equipment Technology Co. Ltd is a professional enterprise specialized in sludge treatment, have abundant engineering experience in sludge treatment, has been approved by the owner.
