     Most of the municipal sludge from urban sewage treatment plant in sewage treatment is solid, semi-solid and liquid waste material. At present, Puyang city sewage treatment scale is increasing, the amount of sludge generated is also increasing. Due to the current lack of Puyang harmless sludge disposal and resource processing system, making the most of the sludge without effective treatment by direct landfill, or piled up in the abandoned wasteland, very easy to cause two pollution to the environment. At present, the society of the pollution of sludge is a relatively high degree of concern, the problem of city sludge treatment and disposal is must be solved as soon as possible. Because, solve the problem of sludge can help to achieve the improvement of the water environment, to prevent pollution two, and can promote the sludge harmless treatment and disposal work. 
     Puyang City area of existing sewage treatment plant 6, which city two, four counties, design sewage processing ability for a total of 25 million T / D, 2009 the actual processing capacity for 13.56 million T / D, produce sludge may 88t/d (to 1 million tons of sewage generated sludge 6.5T) 6 sewage treatment plant environmental impact assessment documents require the sludge sanitary landfill, now in addition to part of the sludge, land use, and the rest are sanitary landfill disposal.
Because of the sewage treatment plant sludge moisture content of 80%, glia, is not easy to dehydration, rheological properties, such as direct access to landfill field will cause difficulty in the rolling, therefore, landfill reject urban sewage treatment plant sludge; also due to the limited forest resources sludge to use a lot of woodland is easy to cause hardening of the soil, resulting in sludge land use space is getting smaller and smaller. Therefore, for the municipal waste water treatment plant sludge seek reasonable disposal method is particularly necessary and urgent.
     After monitoring and monitoring departments, Puyang City, the existing sewage treatment plant indicators of heavy metal pollutants meet the sludge disposal of agricultural mud urban sewage treatment (cj/t309-2009) with mud > and < the urban sewage treatment plant sludge disposal landfill (gb/t23485-2009) pollution control limits. With the development of economy and society, the sewage treatment rate constant to improve, is building second sewage treatment plant in Puyang City, the sewage treatment plant and the East sewage treatment plant, is expected to 2015, the city's total sewage treatment capacity reached 250 thousand t/d, Nissan raw sludge volume will reach to 150t (10 thousand to t 6T meter. The sewage sludge) is expected to 2020, to 300 thousand Puyang city sewage treatment T every day, every day the production will reach 180t (sludge with 10 thousand T waste water to produce 6T sludge. For now, plan) for sludge treatment and disposal in Puyang mainly exist in the following problems: (1) two sludge The secondary pollution problem solving is delayed, because the final disposal method of sludge is not final.
     Sludge treatment and disposal work is currently facing the most cities of our country, this is our country in the process of economic development in heritage left by environmental problems. Sludge treatment and disposal problems and urban environment has a close relationship. Therefore, it is necessary to the sludge reduction, harmless, resource processing to ease the grim situation of municipal sludge. Zhengzhou Taida energy saving drying equipment Technology Co., Ltd. as a professional, with rich experience in engineering, for urban sludge treatment to seek the feasible road, welcome the majority of owners to discuss cooperation.
