Accompanying drawing explanation
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Fig. 1 is the structure principle chart of the BCAS system of process difficult degradation of the present invention and brine waste.
Detailed description of the invention
As it is shown in figure 1, disclosed processes difficult degradation and the BCAS system of brine waste, depend on including by pipeline
The former pond of secondary connection, distribution reservoir, biogas circulation anaerobic reactor (Biogas reactor), mud screening pond (Changed
Tank), anoxic pond (Anoxic tank) and mud separate tank (Settling tank), also include the regulation being connected with distribution reservoir
Pond, high-concentration waste water and low concentration wastewater enter BCAS system by former pond and regulating reservoir respectively, described mud screening pond and
Between biogas circulation anaerobic reactor, between mud separate tank and anoxic pond, connect the most respectively between mud screening pond and anoxic pond
It is connected to sludge return pipe.
Concrete, high-concentration waste water enters former pond, pumps into distribution reservoir by the first distribution pump, and low concentration wastewater is in regulation
After the regulation of pond, pump into distribution reservoir by the second distribution pump.It is 37～39 DEG C that described distribution reservoir controls temperature, and pH is 4～5, in pond
The COD concentration of water distribution is 10000～15000mg/L, pumps into biogas circulation anaerobic reactor by elevator pump.
There is violent reaction with the mud of sludge reflux in the anaerobe in biogas circulation anaerobic reactor, produces substantial amounts of
Biogas, biogas yield coefficient is 0.5～0.6m3Biogas/removal kgCOD, biogas carries under one's arms certain anaerobe with reactor water outlet
Flowing into mud screening pond, mud, after screening, is back to biogas circulation anaerobic reactor, and the mud keeping anaerobic reactor is dense
Degree is 50000～80000mg/L, so that anaerobism efficiency brings up to more than 70%.Biogas circulation anaerobic reactor screens with mud
There is a liquid level difference more than 5m in pond and the certain dissolved oxygen of reentrant, and dissolved oxygen now is at more than 0.5mg/L, screens through mud
Behind pond, dissolved oxygen is reduced to about 0.2mg/L.The clear water in mud screening pond is from flowing into anoxic pond, and anoxic pond relies on the machinery in pond
Stirring, waste water is from flowing into mud separate tank after anoxic pond, and mud screens the unnecessary mud in pond and separates with mud separate tank
Whole sludge refluxes to anoxic pond, it is achieved discharged without residual mud.The sludge concentration of anoxic pond 15000～20000mg/L,
Thus strengthen anoxia efficiency.A small amount of Organic substance after biogas circulation anaerobic reactor is degraded is in anoxic pond, by pond
The anoxia of waste water generation micro dissolution oxygen of mud and dissolved oxygen concentration about 0.2mg/L and anaerobic reaction, dissolved oxygen is organic
Thing and mud run out, and produce certain biogas, it is achieved organic clearance is about 40 ~ 50%.
Substantial amounts of Organic substance produces biogas at anaerobic reactor generation biogas and a small amount of Organic substance anoxic pond and passes through biogas
Collection conduit is transported to methane utilizing system.
The present invention is based on BCAS system, and the Organic substance in waste water realizes clearance in biogas circulation anaerobic reactor and is
More than 70%, realizing clearance in anoxic pond is about 40 ~ 50%, realizes organic removal rate 82 thereby through BCAS system
About ~ 85%.
Used water difficult to degradate brings up to more than 0.5 by B/C after biogas circulation anaerobic reactor than from 0.2, passes through anoxic pond
After, the anaerobic reaction of Organic substance generation anoxia, B/C is reduced to 0.4 than from 0.5.
The pH of distribution reservoir water inlet is 4～5, realizes producing acid and producing by the Organic substance of waste water after biogas circulation anaerobic reactor
Methane process, is engaged in and makes the pH of waste water bring up to 7 ~ 7.5, after anoxic pond, and the anaerobic reactor of waste water generation anoxia, waste water
PH be increased to about 7.8 ~ 8.0.Thus realize acid waste water after BCAS system, reach neutral or alkalescence.
The COD concentration of distribution reservoir water inlet water distribution is 10000～15000mg/L, pumps into biogas circulation anaerobism by elevator pump
After reactor, COD degradation 70%, the COD concentration of biogas circulation anaerobic reactor water outlet is 3000 ~ 4500mg/L.Pass through anoxic pond
Rear COD degradation 40 ~ 50%, the COD concentration of anoxic pond water outlet is about 1500 ~ 2700mg/L, it is achieved that the anaerobism efficiency of waste water
Optimization and maximization.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Will appreciate that present disclosure and implement according to this, can not limit the scope of the invention with this.All according to master of the present invention
