The material filling type baffle bioreactor

Affiliated technical field

The utility model relates to the material filling type baffle bioreactor in a kind of water technology.

Background technology

In sewage disposal,,, be widely used in the processing of municipal effluent (more than 90%) and various industrial organic sewages always in occupation of crucial position because biological treatment has economy, effective and simple.The dominant mechanism of biological treatment is to utilize the metabolic function of microorganism, and organism is carried out biochemical degradation, removes organism and holophytic nutrition thing, and utilizes biofloculation to remove colloidal solid; Simultaneously can also obtain energy and product.But, traditional biological treatment exists some significantly deficiencies: as not keeping the higher concentration of microorganism, treatment scheme and time are long, efficient is not high, the effluent quality instability, a large amount of excess sludges of generation are handled bad meeting and are caused secondary pollution, can't handle the refractory organics material owing to can't keep the existence of specific flora, it is bigger than complexity and occupation of land to handle structures, initial cost and operational and administrative expenses are higher, and energy consumption is big, and the operational management condition is relatively poor etc.

Summary of the invention

The purpose of this utility model and task are exactly at the deficiencies in the prior art, and a kind of novel device that is called the material filling type baffle bioreactor is provided.This device can utilize traverse baffle and filler to form basic bioreactor for treatment unit according to different sewage disposal requirements, in conjunction with suitable aeration and mud reflow method, forms different processing modules, is applicable to the processing of multiple sewage.

The utility model is achieved through the following technical solutions: dose filler and constitute basic bioreactor for treatment unit in the stream chamber that is made of traverse baffle, the installation direction of traverse baffle constitutes upward flow chamber and following to the stream chamber respectively perpendicular to the direction of current; The width of upward flow chamber is down to the 1-8 of stream chamber doubly so that mud down to stream chamber short mix, and in the upward flow chamber, fully assemble, form granule sludge and be attracted on the biologic packing material; Be processed into the flow deflector of 30-60 degree down to the baffle plate its lower edge of stream chamber, be convenient to water is delivered to the center of upward flow chamber, make the muddy water thorough mixing; Filler in the stream chamber can help to obtain good precipitable active sludge down; The filler of various flows chamber not only can be kept the very content of microorganisms of high density, and helps the growth of specified microorganisms population, can handle the refractory organics material.

The beneficial effects of the utility model are, owing in the stream chamber, dosed filler, make the higher concentration that in this device, can keep different microorganisms and the stable existence of specified microorganisms population, be convenient to that different process object is carried out specific aim and handle, significantly improve effluent quality and processing efficiency, reduce and even the elimination sludge discharge, simplify and dwindle the structure and the volume of processing structures, save land used, reduce investment, reduce operational and administrative expenses, improve management condition etc.To basic bioreactor for treatment unit carry out some necessity adjustment and (or) combination, increase corresponding apparatus and can constitute different bio-reactors: as hydrolysis-acidifying bio-reactor; Anaerobic biological reactor; Aerobe reactor; The biological respinse strainer; And the multiple combination of different bio-reactors.
