   Urban sewage treatment plants of disposal and treatment and pollution prevention technical policy aims at driving development of sludge disposal. At the same time, for urban sewage treatment sludge treatment and disposal technology should provide some guidance to the development of what and how to development. And around the promotion of urban sewage treatment plant sludge treatment and disposal of the R & D work and promote the work of, promote energy-saving emission reduction, avoid the sludge secondary pollution to the environment.
   Pollution control technology policy to sludge is "the environment protection law of the people's Republic of China", the people's Republic of China solid waste pollution prevention and control law of the people's Republic of China, urban and rural planning law, the people's Republic of China Water Pollution Prevention Law "and other laws and regulations as the basis for the formulation. It is suitable for semi solid or on a solid substance produced during wastewater treatment (not including the gate slag, dross and sand) production, storage, handling, transportation and final disposal of the whole process of management and technical guidance, sludge treatment and disposal facilities planning, design, construction, inspection, assessment, operation and management. On the basis of source reduction and total process control principle, strengthen the source of toxic and hazardous substances control, according to the security requirements and the final disposal of sludge sludge characteristics, selection of sewage and sludge treatment process.
   The trial also pointed out that the policy of sludge treatment and disposal planning should be integrated into national and local urban sewage treatment facilities construction planning, and the local environmental sanitation, landscaping, land use and other related professional planning coordination; reasonable layout of unified planning. Sludge treatment facilities should be set up relatively centralized, encourage some will focus on urban sewage treatment plant sludge treatment according to the production plan; sludge sludge treatment and disposal facilities reasonably determine the scale, according to a recent volume of sewage and water quality to determine the short-term construction scale. The construction of sewage treatment plant should be based on the sewage sludge treatment facilities, the "three simultaneous" principle. The new sewage treatment plant, expansion, sludge treatment and disposal facilities should be planned, and sewage treatment at the same time, the construction of facilities, and put into operation. The sludge treatment sludge disposal must meet the requirements, do not meet the prescribed requirements of the project can not pass inspection And currently the sludge treatment facilities have yet to meet the disposal requirements, should speed up the construction, ensure the safe disposal of sludge; sludge quantity principle reduction. Construction of waste water treatment plant should be balanced sludge treatment and disposal, and reducing the amount of sludge produced, save the costs of disposal of sludge treatment. For sludge without proper treatment and disposal, subtract the COD reductions; heavy metals and toxic and hazardous substances control principle. Industrial waste water must be in accordance with the provisions of enterprises in the pretreatment, the removal of heavy metals and other toxic and harmful substances, and reach the emission standards stipulated by the state and industry.
 

：There are many problems in sanitary landfill in our country; Future development may meet obstacles； ：Sewage treatment plants face with crisis; Sludge disposal is very important
