          Suggestions on establishing sludge disposal system

             With the continuous improvement of sewage treatment standards and rich, sludge treatment standards and policies there are a lot of loopholes, with respect to the sewage treatment, there is more need to improve the place.
             China's current sewage sludge treatment and disposal of the standard, specification, development is lagging behind, the still does not have a more perfect, scientific sewage sludge treatment disposal standard system, to guide the practice of sludge disposal, hindered the rapid development of sludge disposal in our country. Through the study of economic developed countries sludge disposal and management system, for sludge disposal in our country development suggestions and provide guidance, to avoid the secondary pollution caused by the sludge, which will contribute to the construction of our country "s environmental friendly and resource-saving society.
             Based on the foreign developed countries sludge disposal standard specification system and give full consideration to China's national conditions, China's sewage sludge disposal standard specification system can be from the basic standard, general standard, three levels of product standard construction. The basic standards of urban sewage treatment plant sludge mud factory, disposal of the categories and confining and other laws and regulations basis etc.; universal standards include mud standards, inspection standards, design rules and operating procedures, such as industry standard; product standards is formulated relevant standards for specific segments sludge related products, such as sludge composting equipment, sludge products.
          Land utilization
            The standards for land use shall include, in the fields of agriculture, landscaping, land (saline alkali land, desertification and abandoned mines), etc. the final standard system shall include:
           1. Sludge sludge quality standards: including heavy metals, pathogens, nutrient limitation, pathogen transmission of animal habitat control and restrictions on the organic pollutants.
           2. Place limits of sludge application
           3. For different utilization, different types of soil, the development of different types of sludge application and application of limit.
           4. Transportation and storage limits of land utilization of sludge
           5. Manage, monitor, report and track for sludge application
           6. Design and operation standard
           Landfill
             Landfills should include separate filling and mixed landfill class 2 sub standards. China should be gradually restricted the application of dehydrated sludge landfill. The final sludge landfill standard system should include: Shale requirements, leachate emission limits and management measures, monitoring system, reporting and record system, design and operating norms.
          Use sludge to building materials
            Should include: additions are made of cement, brick, lightweight aggregate concrete standard specification. The final standard system should include: product quality standards for building materials (cement, brick and light aggregate) made of mud and sludge; sludge building material utilization of sludge maximum mixing ratio, sludge produced in the process of building materials management measures, management measures in the process of utilization of sludge building material 1 if applicable occasion 2.
          Incineration
             Incineration should include separate incineration, mixed with garbage burning, utilization of industrial boiler burning standard, send fire incineration power plant and the sub-classes of standard specification. Final standard system should include: sludge into separate incineration furnace mud standard; standard the incineration of sludge and garbage mixed mud standard; sludge sent thermal power plant burning mud standard; sludge utilization of industrial boiler burning mud, sludge incineration furnace flue gas pollution control limit; sludge incineration ash utilization in building materials of access standards; sludge incineration ash disposal management measures; incineration furnace technology research (including incineration furnace technical performance indicators and the incinerator chimney height).
            The preparation of sludge treatment standards should be established a complete, suitable for China's national conditions of the sludge disposal standard system.
