Abstract

The invention provides an integrated oxygen-enriched bioreactor and belongs to the field of biochemical water treatment. The bioreactor comprises a horizontal round reaction tank, wherein a water inlet I, a water inlet II, an air inlet, an air outlet and a vent nozzle are formed in the left end seal of the horizontal round reaction tank; the right end seal part of the round reaction tank is separated into an upper cavity and a lower cavity; the upper cavity is a gas-liquid mixing cavity, a plurality of horizontal separators for static mixing are arranged on the inner wall of the upper cavity; the lower cavity is an oxygen concentration cavity, and a plurality of dispersers for oxygen-enriched concentrate are arranged on the intermediate separator between the upper cavity and the lower cavity, and are used for concentrating oxygen into a part of reflux liquid and quickly dissolving the oxygen in sewage which is biochemically treated through distribution pipelines in the intermediate biochemical reaction area in the tank body after oxygen and nitrogen in compressed air are separated. A sludge-water separator is arranged in the right end of the reaction tank, so that the sludge generated after biochemical reacting treatment can be separated in the sludge-water separator, and the separated and precipitated sludge moves and flows to the front end of the reaction area through a built-in air stripping pipeline, and appropriate circulation is carried to maintain the concentration.

Description

A kind of integrated oxygen enrichment bio-reactor

Technical field

The present invention relates to relate to biochemical process water treatment field, relate in particular to the integrated oxygen enrichment bio-reactor that utilizes Henry's law principle.

Background technology

Industrial Wastewater Treatment, the particularly organic industrial sewage processing of high CODcr value high density, difficult degradation, as industries such as chemical industry, pharmacy, coking, process hides, printing and dyeing, grease, food, distinct issues are that water is seriously polluted, as technique routinely and conventional equipment and technology design, technical process is long, give and process investment greatly, and being difficult to reach can biochemical degradable technical indicator, thereby cause generate subsequent metallization processes long flow path, occupation of land, investment, energy consumption large, and because of often not up to standard, face the problem of proposing mark transformation.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, provide one to utilize Henry's law, make to implement the easier through engineering approaches of pressurized air oxygen enrichment biochemical aeration technology, and investment, cost, occupation of land, working cost and energy-saving effect exceed the integrated oxygen enrichment bio-reactor of external same category of device state of the art.

Key problem in technology of the present invention is the oxygen part in pressurized air to be dissolved in the phegma of part water treatment, and the airborne nitrogen of separating is as the mixing in biochemical treatment process, and microbial film contacts the power of the done pedesis of growing up in sewage.Above-mentioned biochemical reaction process can be placed in completely within integrated oxygen enrichment bio-reactor and complete in the lump, and mode parallel connection that can module is embedded in underground---and this city in north cold area is imperative and option reliably.

More than the present invention can be concentrated to 12mg/l by the oxygen level in sewage, and height is distributed in to reaction interval containing oxygen concentrated solution by arm, again by the mode circulating, oxygen part is distributed in water, its concrete technical scheme is: a kind of integrated oxygen enrichment bio-reactor, comprise horizontal circular retort, circular retort is by left end end socket, reaction zone, stage casing and right-hand member end socket composition, on its left end end socket, offer successively from top to bottom in described left end end socket and be divided into upper and lower two-layer chamber with central dividing plate, in described upper chamber, offer top venting port and water-in I, on upper chamber's inwall, be arranged at intervals with the some horizontal baffles for static mixing, form gas-liquid mixed chamber, described lower chambers offers inlet mouth, water-in II and drain, form oxygen concentration chamber, on described central dividing plate, be provided with the decollator of several oxygen enrichment concentrated solutions, in the bottom cavity of reaction zone, described stage casing, be provided with distribution pipeline line, on described right-hand member end socket, offer water outlet, in its chamber, be provided with separator for mud and water, form swash plate mud-water separation district.

As preferably, in described tank body, be built-in with the air lift pipeline of reaction zone, stage casing front end.

The decollator of described oxygen enrichment concentrated solution is for by after the oxygen of pressurized air and nitrogen separation, and oxygen concentration, in partial reflux liquid, and is dissolved in rapidly just in the sewage of biochemical treatment by the distribution pipeline line in the reaction interval of tank body stage casing.

Described separator for mud and water, the mud that is intended to produce after biochemical reaction is processed is separated in separator for mud and water, and the mud that precipitation separation gets off is by the advection of built-in air lift pipeline to reaction interval front end, and appropriateness circulation, keeps concentration.

Beneficial effect of the present invention: the present invention is specially adapted to the organic waste water of high CODcr value concentration, by Henry's law principle, the oxygen part concentrating in partial reflux liquid is distributed in rapidly in processing water, thereby accelerate the metabolism of microorganism, accelerate to consume the nitration oxidation process of the pollutent that disappears, thereby reach in limited floor area of building, limited investment, limited processing condition, particularly the north need to keep biochemical reaction temperature and corresponding meteorological conditions to reach emission standard, can accomplish again energy-conservation, automatic control, a kind of novel aeration aerating method cheaply simultaneously.The technology of the present invention is applicable to the high concentrated organic wastewater design newly-built or transformation project of middle and small scale and selects, in the time that the processing water yield is larger, can apply patent of the present invention the patented technology arranging in systems engineering is placed in separately to specialty interval, and bring into play the wherein new radiation effect of the heart.
