Example 1
As shown in fig. 1, the biochemical treatment system for oily sewage provided by the utility model comprises an oily sewage pretreatment system 1, and is characterized in that: the sewage pretreatment system 1 with oil is communicated with a fine filter 2, the other side of the fine filter 2 is communicated with a first-stage three-section hydrolysis acidification reactor 3, the other side of the first-stage three-section hydrolysis acidification reactor 3 is communicated with an aerobic biological contact oxidation tank 4, the other side of the aerobic biological contact oxidation tank 4 is communicated with an inclined tube secondary sedimentation tank 5, and the upper part of the inclined tube secondary sedimentation tank 5 is communicated with a deep treatment unit 8.

The hydrolytic acidification is anaerobic hydrolysis with anaerobic technology controlled in hydrolytic acidification stage, the hydrolytic acidification technology is biochemical reaction of incomplete anaerobic method, hydrolytic acidification bacteria are dominant bacteria, and methane bacteria are difficult to reproduce due to elutriation action of water flow in a reaction structure in consideration of different production speeds of methane bacteria and hydrolytic acidification bacteria. The dissolved oxygen in the wastewater should be reduced as much as possible, so that the hydrolytic acidification bacteria are more suitable for propagation. The hydrolysis and acidification treatment technology is a sewage treatment technology aiming at long-chain high polymer and heterocycle-containing organic matter treatment. The hydrolytic acidification bacteria can hydrolyze and acidify long-chain high polymer into organic small molecular alcohol or acid with stronger biodegradability, and also can break down part of non-biochemically or biochemically weak heterocyclic organic matters into biochemically degradable organic molecules; the BOD5/CODCr value of organic pollutants in the sewage is improved, so that the biochemistry of the whole sewage is improved. The hydrolytic acidification tank consists of a tank body and a water distribution system. Anaerobic fermentation of organisms is divided into four stages, namely a hydrolysis stage, an acidification stage, an acidic decay stage and a methanation stage, wherein solid substances are degraded into soluble substances, and macromolecular substances are degraded into micromolecular substances. The hydrolysis acidification tank controls the reaction before the second stage is completed, so that the hydraulic retention time is short, the efficiency is high, and the biodegradability of the sewage is improved. The hydrolytic acidification tank is used as a transition unit for biological contact oxidation, after the hydrolytic acidification tank is started, sewage enters the tank body from the water distribution system, flows upwards from the tank bottom, and when passing through a sludge layer and a filler layer formed by bacteria, the sludge layer adsorbs suspended matters and organic matters, performs net capturing, biological flocculation and biological degradation, so that the sewage is clarified while degrading COD. The filler layer is arranged to improve the stability and the microbial biomass of the sludge layer of the hydrolytic acidification tank. The hydrolysis acidification process is mainly used for leading the macromolecular organic matters which are difficult to degrade and are broken by ring opening to become small molecular matters which are easy to biodegrade, and has important significance for improving the biodegradability of the wastewater. In the hydrolysis tank, the fermenting bacteria hydrolyze complex organic substances (including polysaccharides, fats, proteins, etc.) in the sewage into organic acids and alcohols. In the acidification stage, the hydrogen-producing and acetic acid-producing bacteria metabolize organic acid and alcohols of fermentation products into acetic acid and hydrogen, so that macromolecular substances are degraded into micromolecular substances, and solid substances difficult to biochemically degrade into easily-biochemical soluble substances, thereby improving the biodegradability of wastewater.
The biological treatment is a link after physical and chemical treatment, and is also an important link in the whole circulation flow, harmful substances such as ammonia nitrogen, nitrous acid, nitrate, hydrogen sulfide and the like are removed, and the biological treatment plays a key role in further treatment of water quality in the subsequent flow.
The biological contact oxidation method is a biological membrane process between an activated sludge method and a biological filter tank, and takes a biological membrane attached to a filler (polyethylene plus alcoholized yarn as a material) as a main material, wherein the filler is arranged in the tank, the aeration at the bottom of the tank is used for oxygenating sewage and the sewage in the tank is in a flowing state so as to ensure that the sewage is fully contacted with the filler in the sewage, and the defect of uneven contact between the sewage and the filler in the biological contact oxidation tank is avoided. Has the characteristics of high efficiency, energy saving, small occupied area, impact load resistance, convenient operation management and the like. In the method, the oxygen required by microorganisms is supplied by blast aeration, after the biofilm grows to a certain thickness, the microorganisms on the filler wall can be subjected to anaerobic metabolism due to oxygen deficiency, and the generated gas and scouring action formed by aeration cause the falling of the biofilm and promote the growth of a new biofilm, and at the moment, the falling biofilm flows out of the pond along with effluent.
Basic characteristics are as follows: (1) Because the specific surface area of the filler is large, the oxygenation condition in the tank is good, and the biosolids amount per unit volume in the tank is high, the biosurface oxidation tank has high volume load; (2) The biological contact oxidation pond has a large amount of biological solids, and water flows are completely mixed, so that the device has strong adaptability to sudden changes of water quality and water quantity; (3) The residual sludge is small in quantity, the problem of sludge expansion is avoided, and the operation management is simple and convenient.
In summary, the biological contact oxidation method has the basic characteristics of a biological membrane method, but is different from a common biological membrane method. Firstly, the filler for microorganism to attach is fully immersed in the wastewater, so the biological contact oxidation Chi Youchen submerged filter tank. And secondly, the mechanical equipment is adopted to oxygenate the wastewater, and the method is different from the common biological filter which is used for naturally ventilating and supplying oxygen, and is equivalent to adding a filler for microorganism to attach in an aeration tank, and the method can also be called an aeration circulation type filter or a contact aeration tank. Thirdly, about 2 to 5 percent of suspended activated sludge also exists in the wastewater in the tank, and the wastewater is purified. Therefore, the biological contact oxidation method is a biological membrane method with the characteristics of an activated sludge method, and has the advantages of both the biological membrane method and the activated sludge method. The basic principle of the biological contact oxidation method for purifying the wastewater is the same as that of a common biological membrane method, namely, organic matters in the wastewater are adsorbed by the biological membrane, and the organic matters are oxidized and decomposed by microorganisms under the aerobic condition, so that the wastewater is purified. The biofilm in the biological contact oxidation pond consists of zoogloea, filamentous fungi, protozoa and metazoan. In the activated sludge process, filamentous fungi are often factors that affect normal biological purification; in the biological contact oxidation pond, the filamentous bacteria are in a three-dimensional structure among gaps of the filler, so that the contact surface of biological phase and wastewater is greatly increased, and meanwhile, the filamentous bacteria have strong oxidation capability to most organic matters and have strong adaptability to water quality load change, so that the filamentous bacteria are powerful factors for improving the purification capability.

The effluent from the aerobic biological contact oxidation tank 4 automatically flows into a chute secondary sedimentation tank 5, the water and the mud are further separated, the mud enters a mud collecting tank 6, the mud in the mud collecting tank 6 is conveyed to a factory mud treatment system through an oil pump, and the effluent automatically flows into a subsequent sewage advanced treatment unit 8.
