               Our country sludge treatment disposal problems being paid attention to day by day, the standards for sludge system, the revision work will continue to carry out, related to the system, also in the continuous improvement. But sludge standard system of our country lack of sludge disposal environmental standards category this important standard of sludge treatment, such as sludge incineration standards, sludge compost standards, to guide the sludge treatment disposal is very bad. Construction and perfect the standard system of sludge in China to sludge from generation to the treatment and disposal of the whole process focus, not only to further system, revised urban sewage treatment plant pollutant discharge standards, the sludge mud and product standards and supervisions.
             In recent years, our state has also made laws and regulations on supervising mud quality in incineration and landfill, which Only limited to the production and operation of the specification, only for the use of incineration and landfill disposal.
          1. Suggestions on building sludge disposal system
             Build and perfect the standard system of sludge in China to sludge from generation to the treatment and disposal of the whole process focus, not only to further system, revised urban sewage treatment plant pollutant discharge standard, muddy sludge and other product standards and monitoring analysis method standard, should also vigorously strengthen the sludge treatment disposal environmental standards formulation.
           2. Environmental protection standards on sludge disposal
             Ways of sludge disposal include incineration, land use, building materials and landfill. However, our country has no environmental standards for sludge treatment and disposal, especially for sludge treatment and disposal process of pollutant emission standards, can not meet the requirement of the actual work. As soon as possible from the technical policy, technical specifications, sewage sludge, pollutant emission control on construction of sludge treatment and disposal system of environmental protection standards. At present, sludge disposal and pollution control technology policy of urban sewage treatment (Trial) 6 has been issued, regulate the disposal of sewage sludge treatment technology in the revision process, the quality standard is part of the sludge has been introduced, sludge treatment and disposal of pollutant emission standards should be formulated.
            3. Environmental protection standards on land utilization of sludge
             As a major developing country, land use is a kind of main disposal method for disposing sludge. According to the use of different forms, can be divided into the sewage sludge sludge land use standards for environmental protection, landscaping and improving soil environmental standards, they are related to environmental standards. Sewage sludge compost in agricultural sludge pollutant control standard 6 (gb4284) 84) due to the formulation of the time early, the index is not comprehensive, lack of implementation and management rules etc. the problem has been unable to meet the present stage, the revised management needs urgently. Currently, 5 of urban sewage treatment plant pollutant discharge standard is being revised in 6, sludge pollutant emission control, the need to strengthen the source control and stabilization of sludge content such as heavy metals and other harmful substances, but also consider increasing the sludge compost environmental standards, city sewage pretreatment standard. Taking into account the existing standard of our country in the heavy metal sludge, volatile organic compounds and carcinogens and other indicators limit is already the world's one of the most stringent, the next step The focus of the work from the application and monitoring methods and other aspects of management, to ensure that the sludge agricultural safety, environmental protection.
          4. Environmental protection standards for sludge incineration
            Sludge incineration including separate incineration and burning and mixing (or co incineration), mixed burning and can be divided into mixed with MSW incineration, using industrial furnaces (kilns burning, Thermal Power Plant Co firing, etc.. According to the needs of environmental management can separately formulate the incineration of environmental standards, also can be in the standard revision process containing sludge incineration.
           5. Environmental protection standards for landfill and building materials utilization
             At present, mixed sludge landfill is still the sludge treatment and disposal of the one of the main ways, mixed landfill general in accordance with 5 municipal solid waste landfill pollution control standard 6 GB16889 2008 [26] were. Based on the reduction of greenhouse gas emissions, 5 urban sewage processing plant sludge treatment disposal and pollution control technology policy (for Trial Implementation) 6 put forward in our country will be gradually eliminated and limitation for sludge landfill directly. On the basis of, our country will be garbage and sludge disposal development timely development of new control measures according to the real development situation.  
            Using sludge for building materials is an effective way at present. At present, our country sludge utilization in building materials include brick, cement, light weight aggregate of fiberboard or ceramic other building materials. However, our country haven't long-term operation of actual engineering, need according to the actual situation, timely formulate relevant environmental protection standards. At present, the Ministry of environmental protection has started using a variety of solid waste production of building materials environmental protection control standard, of which about cement product environmental protection control standard has completed the first draft.
            6. Method of test and regulation of management circle
             Sludge test method standard to meet the requirements of the other sludge standards of monitoring, and with the other sludge standards, revised and updated accordingly. As for the sludge monitoring monitoring and sampling frequency requirements, should according to the specific requirements of the different categories of standards respectively in the standard single provisions. Standard implementation and management and index set are equally important. European Union, the United States, German and British sludge standards provisions of the amount of sludge, main composition and concentration, transfer of both sides and other related information recording and reporting system. sludge standard in our country this is still in the blank stage, should be established as soon as the sewage treatment plant, the local environmental protection administrative department and the final landmark between linked single system. At the same time, China should learn from foreign experience, in the standard provisions should be regularly to the public announced sludge inspection test results, sludge treatment and disposal and utilization of.
             In a word, our country need as soon as possible to develop sludge treatment and disposal environmental standards, revised urban sewage processing plant pollutant discharge standards and sludge test method standard, build and perfect the standard system of sludge in China. Sludge treatment and disposal standard system similarly to can play a supporting role, many experts said, the current sludge treatment industry is relatively confusing, need to be reasonable sludge disposal technical guidance, norms and guidelines for the sludge treatment disposal market.
