Description
Technical field
The present invention relates to environment protection and technical field of waste water processing, especially relate to a kind of Sewage treatment systems and method that contains high-proportion industrial waste water.
Background technology
The trade effluent proportion that sanitary sewage is mixed with in the municipal sewage plant is higher, and to have many be the waste water of difficult for biological degradation, causes the water outlet can not stably reaching standard.
Reactor for hydrolysis and acidification belongs to the technology category of up flow anaerobic sludge blanket reactor, sewage enters reactor by reactor bottom, pass through Sludge Bed, organic particle material during a large amount of microorganisms will be intake and colloidalmaterial are held back rapidly and are adsorbed, this is the rapid reaction of a physical process, and general needs several seconds to tens seconds time to finish.The material that is retained down is adsorbed on the surface of hydrolyzing sludge, the metabolism that is decomposed slowly, and it is greater than hydraulic detention time at intrasystem sludge retention time.Under the effect of a large amount of hydrolytic bacterias, insoluble organism is broken down into dissolved matter, simultaneously under the synergy of acid-producing bacteria with macromolecular substance, be difficult to biodegradable material and be converted into and be easy to biodegradable small-molecule substance, again be discharged in the waste water, under higher hydraulic load, flow out system with water.Because the generation time of hydrolysis and acid formers is shorter, often in minute and hour, therefore, this degradation process is rapidly.In this process, though the clearance of solvability COD, BOD5 is very low from the surface, but because particulate organic matter generation hydrolysis has increased the concentration of dissolved organic matter in the system, therefore, it is very high that the clearance of solvability COD, BOD5 is actually, the part of removing is present in waste water and the mud with CH4, CO2 and these three kinds of forms of thalline increment, and particularly the solubleness of CH4 and CO2 also is appreciable in low concentration wastewater.As seen from the above, hydrolysis reactor integrates precipitation, absorption, biofloculation and biological degradation function.The removal of organism in hydrolysis reaction bath comprised physics, chemistry and biochemical combined reaction process.This has essential difference with the preliminary sedimentation tank that has only the physical sedimentation function.Therefore, hydrolysis reaction is a kind of novel sewage treatment process.Much more the acidication treatment process of waste water has research at home and abroad as the Biological Pretreatment technology and uses.It can improve the sewage biochemical property, reduces the subsequent biological treatment load.
Therefore, how in conjunction with prior art, the design high efficiency, low cost is handled sink drainage and the method that contains high-proportion industrial waste water, is the target of technician's concern always.
Summary of the invention
