Water drainage pipeline sludge organic and inorganic component on-line separation carbon source extraction system and method

Abstract

The invention relates to a drainage pipeline sludge organic and inorganic component online separation carbon source extraction system and method.The extraction system comprises a system outer box, a system body is arranged in the system outer box, and the system body sequentially comprises a deodorization module, a pretreatment module and a cyclone separation module which are spliced together from top to bottom; a grid residue squeezing module is arranged on the side wall of the upper part of the cyclone separation module, and the pretreatment module, the cyclone separation module and the grid residue squeezing module are electrically connected with the control module respectively. A drainage pipeline sludge organic and inorganic component on-line separation carbon source extraction system is adopted to carry out on-line on-site rapid treatment on dredging sludge of a drainage pipeline network; the practical problems that greenhouse gases such as CO2 and CH4 are generated, the transportation workload of a large amount of desilted sludge is large, non-point source pollution is generated due to leakage of the sludge in the transportation process, and construction land of a centralized sludge treatment station is difficult to select in an existing centralized treatment and disposal method for desilted sludge of an urban drainage pipe network can be solved.

Description

technical field [0001] The invention belongs to the technical field of drainage, and in particular relates to a carbon source extraction system and method for on-line separation of organic and inorganic components of sludge in a drainage pipeline. Background technique [0002] Different from developed countries such as Europe and the United States, my country's urban sewage collection pipe network generally has practical operation problems such as high water level and low flow rate, which lead to the deposition of a large amount of particulate organic matter in the sewage. , is the main reason for the low rate of centralized collection of urban domestic sewage in my country. According to statistics, the national average centralized collection rate of sewage in 2020 is only 64%, and only 20%-30% in many cities. The sludge deposited in the pipe network will also affect the efficiency of sewage collection and produce a large amount of CH anaerobic. 4 and other greenhouse gases,...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a system and method for the online separation of organic and inorganic components of drainage pipe sludge and carbon source extraction system. The on-line and on-site rapid treatment of dredging sludge in the drainage pipe network can solve the common problem of CO generation in the centralized treatment and disposal of dredging sludge in the existing urban drainage pipe network. 2 、CH 4 Practical problems such as greenhouse gases, large amount of dredging sludge transportation workload, non-point source pollution caused by sludge running, dripping and leaking during transportation, difficulty in selecting construction land for centralized sludge treatment station, etc.
