Description
Technical field
The present invention relates to technical field of sewage, especially a kind of activated sludge sewage processing system aerator.
Background technology
SBR is the abbreviation of sequencing batch active sludge, is a kind of activated sludge sewage run by intermittent aerating mode
Treatment technology.The core of its orderly and intermittently operated being mainly characterized by operationally, SBR technologies is sbr reactor pond, the pond
Collect homogenizing, just heavy, biodegradable, two functions such as heavy in a pond, no sludge recirculation system is particularly suitable for intermittent discharge and flow
The occasion changed greatly;The aerobic situation for the microorganism that biological treatment is acted on according to participation, can be divided into aerobic method and anaerobic process
Two major classes.Ordinary circumstance, aerobic method are relatively specific for low concentration sewage, such as sewage in ethylene plant;And anaerobic process is relatively suitable for place
Manage the sewage of sludge and higher concentration.Aerobic biological process method can be divided into activated sludge process and biofilm two major classes, in sewage
In the aeration tank for handling biochemical system, oxygen-transfer efficiency and being positively correlated property of growth of aerobic microorganisms amount, the supply amount of dissolved oxygen are wanted
Considered according to the quantity of aerobic microbiological, physiological property, medium property and concentration, in this way, activated sludge can be just in
The state of best degradation of organic substances.
Dissolved oxygen maintains 3~4mg/L and is advisable in aeration tank, if for hypoxgia, activated sludge performance is poor, causes at waste water
It manages effect to decline, to ensure the oxygen supply for having sufficient, it is necessary to complete by a kind of equipment, such as aerator, aerator are discharges
The necessary equipment of water aeration aerating can be divided into surface aerator and underwater aerator by application method, and underwater aerator mainly has
Micro-hole aerator and jet aerator, and its is complicated for existing aerator, is not easy to install and use, aeration area is thought
Will the timeliness of its bigger installation expend more, and installation space occupancy is high, and aeration efficiency is low.
Invention content
The goal of the invention of the present invention is：In view of the above problems, a kind of activated sludge sewage processing system is provided
Solves existing aerator by designing a kind of aerator by deep water and surface aeration combination with aerator
Complicated, cumbersome, installation space accounting is high, the problem of being unfavorable for the high efficiency of sewage disposal, simple in structure, energy saving
