Description

Biochemical process sewage treatment unit peculiar to vessel

Technical field

The utility model relates to a kind of biochemical process sewage treatment unit peculiar to vessel.

Background technology

The sanitary sewage disposal method mainly contains physics method, chemical method, physico-chemical processes and biochemical process, adopting biochemical process to handle sanitary sewage is a kind of low-cost processes method of save energy, it is to utilize active sludge and microbial film to come sewage is handled, organism in the sewage is decomposed into innoxious substances such as carbonic acid gas and water, mud then forms floccule mass and water sepn.Biology in active sludge and the microbial film is based on aerobic bacteria, and with seston, protozoon, metazoan and algae, adds medicament through sedimentary water and bacterium killed the back and discharge.The present biochemical process peculiar to vessel device of disposing of sewage is made up of catchment cabinet and aeration tube of aerate cabinet, sump tank, sterilization, be provided with soft-filler in the aerate cabinet, soft-filler easily hardens, cause biomembranous inefficacy, the biochemical oxygen demand (BOD) BOD clearance in its summer is about 92%--94%, and the biochemical oxygen demand (BOD) BOD clearance in winter is about 60%-65%, and the processing load gradient of whole device can not draw away, can not accomplish efficient oxygenation and the quick hydrolysis of looking thing is arranged, sewage treating efficiency is low.

Summary of the invention

The utility model provides a kind of biochemical process sewage treatment unit peculiar to vessel, and it has solved a biomembranous high keto consumpting speed of high-concentration sewage and an efficient oxygenation equilibrated difficult problem, keeps the continuous high-efficient running that microbial film is handled, and reaches high load and the effect stability handled.

The technical solution of the utility model is as follows: a kind of biochemical process sewage treatment unit peculiar to vessel, it comprises first solarization air cell, second solarization air cell, settling chamber, sterilization collecting chamber and aeration tube, be provided with rigid filled in described first solarization air cell, described rigid filled be that multiaspect is spherical, described aeration tube is micron-sized ultramicropore aeration flexible pipe.

Be serially connected with before described first solarization air cell and regulate the chamber, regulate the chamber and communicate with sewage inlet pipe, regulate the ultramicropore aeration flexible pipe that is provided with in the chamber and be connected with source of the gas, regulate outside the chamber and be provided with macerator pump, the water-in of macerator pump and water outlet are connected with the adjusting chamber respectively; The water-in of described macerator pump communicates with the bottom of regulating the chamber, and the water outlet of macerator pump communicates with the top of regulating the chamber.

After adopting technique scheme, solarization air cell, adjusting are adopted micron-sized ultramicropore aeration in the chamber, and the contact gear ratio surface-area of bubble and water is big, oxygen therapy efficient height.Adopt ultramicropore aeration and the spherical rigid filled oxygenation that cooperates of multiaspect, the increase bubble adheres on filler stations; The water-in of macerator pump communicates with the bottom of regulating the chamber, then regulates the countercurrent flow of drawing water of the buoyance lift and the macerator pump of microbubble in the chamber, has in a disguised form increased the aeration depth of water; Macerator pump is in the comminuted suspension solid while, and its impeller has increased the mass transfer reaction speed of oxygen to air-water mixture pressurization and shearing; The water outlet of macerator pump communicates with the top of regulating the chamber, and the then water outlet of pump and the gas shock of top, chamber causes the effect of drop oxygenation, make oxygenation after water oxygen level near saturation concentration, reach the effect of efficient oxygenation.In efficient oxygenation, sewage has certain residence time through filler, form microbial film at filling surface, under aerobic condition, the a large amount of aerobic microbiologicals of breeding on the microbial film, play organic effect in purification and the degradation of sewage, because the spherical rigid filled specific surface area of multiaspect is big, formed microbial film and organic contact surface increase greatly, then biomembranous metabolism is accelerated, and has quickened organic degraded, and the oxygen-consumption in the solarization air cell is also accelerated greatly, solve a biomembranous high oxygen-consumption and an efficient oxygenation equilibrated difficult problem in sewage, improved the processing load of first solarization air cell.The high oxygen-consumption of first solarization air cell makes that oxygen level reduces greatly in the water outlet of first solarization air cell, and oxygen concentration gradient strengthens, and helps the efficient oxygenation in second solarization air cell.This BOD clearance that installs first solarization air cell can reach 75%, and the clearance of whole flow process BOD reaches 97%, and effluent quality is good.
