Analysis on Project Practice of Urban Sewer Sludge Treatment and Disposal in a Southern Jiangsu City
摘要
Abstract
[Objective]With the in-depth development of the comprehensive treatment of urban water environment,the cleaning and maintenance of drainage pipelines by the maintenance department of urban pipeline has gradually become a normalized measure,resulting in an increase in the production of sewer sludge.Therefore,it is urgent to explore disposal effects and operation costs.[Methods]The operation process and disposal methods of the main sewer sludge treatment stations in Jiangsu Province were summarized in this paper.Taking the sewer sludge treatment station in the urban area of a city in southern Jiangsu as the research object,the calculation of sewer sludge production and the engineering design of the disposal system were explored,and also the disposal effect and operating cost were examined.[Results]The majority of sewer sludge treatment in Jiangsu Province currently employed wet mechanical processes.The project processing scale of the case was 60 t/d,and the core technology of wet separation was used to solve the problem of garbage accumulation and winding in the process of material sorting,and the multi-stage separation of products was realized,and the sand separation efficiency was as high as 97％.The slag material with particle size of over 3 mm,light organic matter with particle size from 0.1 mm to 3 mm,and mud cake with particle size less than 0.1 mm were transported to the landfill for disposal,and the sand with particle size from 0.1 mm to 3 mm was recycled for building materials.The effluent was transferred to a nearby wastewater treatment plant for processing.[Conclusion]This project,through the dewatering and volume reduction of sewer sludge,reduces the amount of material transported to landfills,saving transportation cost and valuable land resources.By screening and washing the sand in the sludge,it is beneficial for resource utilization.Additionally,the washing and pressing dewatering process minimizes the impact on the nearby wastewater treatment plant.The project has yielded positive social and environmental benefits.This project provides the reference for the treatment and disposal of sewer sludge.关键词
