Problems solved by technology
This additional carbon source is a large part of the daily operating cost of the sewage plant, which increases the cost of sewage treatment, and is also one of the main factors that restrict municipal sewage plants from achieving low carbon, carbon neutrality, and carbon surplus.

The invention discloses a high-efficiency anaerobic sludge carbon source recovery system, which comprises: a pool body; the sludge distributor is arranged above the tank body, and the sludge distributor is connected with the sludge-water mixing and conveying pipe; the central vertical shaft is vertically arranged in the tank body, and the top of the central vertical shaft is connected with an outlet of the sludge distributor; the vortex mud distribution unit is arranged at the bottom of the pool body, and an inlet of the vortex mud distribution unit is connected with the lower part of the central vertical shaft; and the three-phase separator is arranged in the tank body. The vortex sludge distribution unit is used for hydraulically stirring a sludge-water mixture, so that a sludge-water mixed solution in the tank body is uniformly mixed, no dead zone exists during stirring, sludge and microorganisms in the sludge hydrolysis reaction zone are fully contacted and reacted, contact between the microorganisms and the sludge is enhanced, the microbiota structure can be obviously changed, and the process operation stability is improved; the hydrolysis efficiency of microorganisms on excess sludge extracellular polymeric substances is improved, so that a high-quality carbon source is provided for a sewage treatment biochemical system.
Description
technical field [0001] The invention relates to the technical fields of sewage treatment, sludge reduction and carbon emission reduction of sewage plants, in particular to a high-efficiency anaerobic sludge carbon source recovery system. Background technique [0002] With the popularization of sewage treatment facilities, the increase of treatment capacity, the improvement of treatment standards and the expansion of treatment functions, the output of biochemical reaction excess sludge has also increased significantly. Sludge generally contains a large amount of organic matter, rich in nitrogen, phosphorus and other substances, which can be effectively used. At the same time, the untreated sludge also contains heavy metals, pathogenic bacteria, parasites and some organic poisons that are difficult to decompose. , the discharge will cause serious secondary pollution to the environment. The investment and operation cost of sludge treatment accounts for about 15% of the investm...
