Description

A kind of anaerobic aerobic integratedization reactor

Technical field

This utility model relates to apparatus for treating sewage, particularly relates to a kind of anaerobic aerobic integratedization reactor, belongs to environmental protection neck Territory.

Background technology

At present, the technique of Dairy Industry sewage disposal is usually anaerobic treatment+aerobic treatment process, and two process single Unit is independent processing system, and anaerobic effluent, after anaerobic treatment, is introduced aerobic unit and pollutes by treatment sewage Degrading again of material.Research shows to use at least existence in this technique following not enough:

(1) two overlaps single technique unit, and floor space is big, and cost is high；

(2) Dairy Industry sewage is higher containing lactoprotein and casein, easily occurs on anaerobic sludge in processing procedure The floating phenomenon separated, causes anaerobic sludge to run off serious, and anaerobic sludge to be anaerobic system degradation of contaminant mainly undertake Person, once sludge loss needs renewed vaccination to buy anaerobic sludge, period system recovery need 2～3 months, there is draining Problem the most up to standard, environmental risk is very big；Additionally, the minimizing of anaerobic sludge causes system fluctuation of service the most at last, Causing and increase aerobic unit load, sludge output is big, increases sewage disposal expense；

(3) easily occur system to become sour when anaerobism influent load raises, cause pH to reduce, microorganism deactivated, detest Oxygen unit mud runs off further, and final disposal ability reduces.

For solving the technical problem that anaerobic sludge runs off, it is anti-that CN203411391U discloses a kind of upflow anaerobic sludge Answering device, this reactor is to set a zeolite filler district between suspended sludge bed and three phase separator, and this zeolite filler district can Effectively stoping the loss of anaerobic sludge, microorganism simultaneously can grow on zeolite, the beneficially process of sewage.But this Class Sludge Bed packing area with run the time increase easily blockage phenomenon, make anaerobic system occur short flowing to and local Become sour.

CN100506721C discloses the device improving three phase separating efficiency of baffle type anaerobic biological reactor, this device The loss that anaerobic sludge causes is reduced due to waterpower and aerogenesis by arranging the baffle plate of multiple band corner.Yet with needs Arranging multiple corner units, the load of anaerobic pond can not be too high, and processed in units amount load height still exists sludge loss and asks Topic.

The technical scheme that anaerobic sludge runs off is solved although prior art provides, due to the defect being individually present, its Being not particularly suited for Dairy Industry sewage disposal, therefore, floor space is little, cost is low, can reduce anaerobism to find one The reactor of sludge loss is that this area is needed badly and solved the technical problem that.

Utility model content

One of the purpose of this utility model is to provide a kind of anaerobic aerobic integratedization reactor, described anaerobic aerobic integrated Change reactor and there is the advantage that floor space is little, cost is low and can reduce anaerobic sludge loss.
