Sludge treatment, 41.18% of the small and medium-sized cities sewage treatment plant directly to the moisture content of 80% of the sludge health landfill pipe filter, only a small number of sewage treatment plants using incineration, c omposting and other processing. Reclaimed water reuse, 76.67% of the sewage treatment plant back the amount to zero. Drainage and sewage treatment status quo of small and medium-sized cities, 17 small and medium-sized cities participating in the survey (both in our country in the eastern province of), including 18 sewage treatment plants. Its problems first manifested in the plans for the building management limitations: the majority of small and medium-sized cities drainage and the construction of sewage treatment facilities limited to the drainage network and the construction of the sewage treatment plant, and the sludge disposal and use of reclaimed water and rainwater utilization, waterlogging prevention and other lack of investment. The survey results show that: the dispersion of small and medium-sized cities sewage treatment plant construction units, management units and management in the form of dispersion, the water company, Housing and Urban-Rural Development Bureau , Water, Environmental Protection Agency is the main building and management units, accounting for less.

In the past 10 years, the development of China s urbanization has made unprecedented achievements, which changed the face of the city, to improve the quality of people s lives. Finally, the reconstruction light tube widespread. Small and medium-sized cities in the drainage and sewage treatment facilities management prevalent lack of routine inspections, maintenance, repair, and other problems, lack of of professional drainage management capacity and operation of the facility. Management of emergencies often in a passive state, payable to the lack of prevention and control mechanisms and response measures. 47% of the cities participating in the survey no pipe network management costs, need to apply to financial problems, temporary c osts; annual fixed maintenance costs only 25% of the budget, the fixed cost of the overhaul and refurbishment budget by 17%.

First of all, the small and medium-sized urban drainage management on the prevalence of bulls flood Construction Committee pipe project, EPA pipe sewage treatment plants, urban management and law enforcement bureau tube monitor, not a department responsible for drainage management system and sewage treatment problems, multiple management at the same time resulting in a lot of things are not in charge of the department. The survey shows that the large majority of small and medium-sized urban sewage treatment plant hit by the industrial waste water, 55% of the sewage treatment plant daily, weekly, or monthly by the more serious water quality impact. Water impact is also worthy of attention, when it rains (more moderate), wastewater treatment plant into the water to increase more than the normal 20% 7, more than the normal 50% 4.

Com pared to outside the city landscape, urban infrastructure is still very weak, and there are also a lot of problems as the urban vein urban drainage management and sewage treatment, pipe filters, including the lack of drainage network, water pollution, water shortages, urban waterlogging including flooding in the city, has also become one of the typical urban disease plagued the development of the city. The main responsibility of the day-to-day management of legal uncertainty, the lack of a basis for enforcement, law enforcement is obviously insufficient, as many small and medium-sized cities there is a wide range of sewage irrigation, but can not tell who the by tube. Especially for water pollution in the hardest hit - the management of the industrial park, is the lack of targeted management measures and environmental safety warning, emergency prevention and control measures.
