Ecological circulation system for harmless recycling of city pipe network sludge

Abstract

The invention discloses an ecological circulation system for harmless recycling of city pipe network sludge. The system comprises an initial end for inputting sludge into the system, the output end ofthe initial end of the system is connected with a biological reaction box through a pipeline, the output end of the biological reaction box is connected with a Aeolosoma hemprichii breeding biological pile through a pipeline, and the output end of the Aeolosoma hemprichii breeding biological pile is connected with the input end of an Aeolosoma hemprichii manure separator through a pipeline. The system greatly reduces the pollution of the city pipe network sludge to the environment, and effectively purifies air; and a biotechnology adopted in the invention greatly reduces harmful substances ofvarious products in the system, and harmlessly recycles pollutants, so that secondary pollution is avoided, safe plantation of crops is facilitated, the land use amount and the energy consumption arereduced, and large-scale treatment of the city pipe network sludge is realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an ecological cycle system for harmless resource utilization of urban pipe network sludge. Background technique [0002] In recent years, my country's urban sewage treatment business has achieved great development, which has greatly improved my country's water environment. However, the rapid increase of water treatment plants and sewage treatment volume has led to a sharp increase in the total amount of sewage sludge produced by urban sewage treatment plants in the process of sewage treatment, which has become a new threat source of environmental pollution in my country's cities. [0003] According to statistics, the main methods of sewage sludge disposal in urban sewage treatment plants in my country are agricultural utilization, landfill, and other disposal (including incineration), and the investment for sludge treatment and disposal accounts for about 20-50% of the t...
