Municipal Sewage Sludge Treatment And Disposal

Municipal sludge including municipal sewage sludge, sewage sludge and river sludge, municipal sewage sludge treatment and disposal of which the most difficult and regulation. Such sludge is both "resource" but also with "harmful", while sludge contains plant nutrients required and combustible organic components, on the other hand contain heavy metals, harmful bacteria, and other refractory organics toxic and hazardous substan ces. Such as the rational use of energy, will give full play to the value of the sludge, turning waste into treasure, if not safe disposal, and will cause serious secondary pollution.With the development of society and economy, the urbanization rate continues to improve, sewage treatment facilities continues to increase, while the city of sludge production is also increasing rapidly, the sludge has become the new challenges of urban development. These problems in the higher level of urbanization areas is even more severe, the sludge outlet is imminent in some areas, even a "sludge siege" phenomenon.Shenzhen Municipal sewage sludge is facing a grim situation: on the one hand, the urban sewage sludge production is increasing, residents have become increasingly demanding environmental protection, on the other hand,the current serious shortage of sludge treatment and disposal capacity, sludge treatment and disposal process lacke d supervision, sludge treatment and disposal facilities construction process, "NIMBY"(not in my yard) highlights the planning and construction difficulties.By analyzing the current disposal of Shenzhen sludge treatment, sludge treatment and disposal comprehensive comparison of domestic and foreign technology and management systems, sludge treatment and disposal of different technologies and processes and sludge management system at home and abroad a comprehensive evaluation by analyzing Shenzhen sludge treatment and disposal facilities construction process causes "NIMBY" and for the Shenzhen existing sludge treatment and disposal problems in the way proposed: encourage qualified wastewater treatment plant for dewatering facilities deep dehydration transformation, and optimization economic feasibility programs; establish integrated management platform sludge treatment and disposal of sludge treatment and disposal management of the entire process; sludge industry to develop policies to encourage enterprise cooperation with neighboring cities centralized coordination of sludge disposal; establish sludge disposal research fund to encourage scientific research institutes and enterprises for sludge treatment and disposal of advanced technology research and development; improve environmental protection publicity and education system, strengthen the public’s "environmental education; to encourage the establishment of community environmental groups, industry associations and third-party assessment of sludge monitoring bodies.Conclusion : The dewatering of sewage treatment plant transformation technology for deep dehydration can greatly reduce the pressure on the Shenzhen Municipal sludge treatment and disposal, and reduce the risk of sludge treatment and disposal; slud ge treatment and disposal through an integrated management platform that can strengthen and improve the existing management system can effectively alleviate the "NIMBY" problem, will help complete construction plan of treatment and disposal facility as soo n as possible.
