Description
Technical Field
The utility model relates to a water purification technical field especially relates to a high toxicity, difficult degradation effluent disposal system.
Background
The technical problems of the common high-concentration collecting and preprocessing system are as follows: the high-concentration wastewater in a workshop is collected uniformly, the pretreatment pertinence is not strong, and the effect of detoxifying a certain substance cannot be achieved.
The hydrolysis treatment method is a method between aerobic and anaerobic treatment methods, and can reduce treatment cost and improve treatment efficiency by combining with other processes, wherein hydrolysis refers to biochemical reaction carried out outside cells before organic matters enter microbial cells.
The principle is as follows: the hydrolysis acidification tank is divided into a sludge bed area and a clear water layer area, and sewage to be treated enters the tank from the bottom of the reactor and is quickly and uniformly mixed with a sludge bed through a water distributor or a water inlet pipeline. The sludge bed is thick, similar to a filter layer, so that particulate matter and colloidal matter in the influent water are rapidly trapped and adsorbed. Because the sludge bed contains high-concentration facultative microorganisms, under the anoxic condition in the tank, the entrapped organic substances hydrolyze insoluble organic substances into soluble substances under the action of a large amount of hydrolysis-acid-producing bacteria, and the macromolecular and difficultly biodegradable substances are converted into easily biodegradable substances.
The technical problems of the existing hydrolysis acidification system are as follows: the backflow is small, the detoxification effect on the wastewater is small, the water distributor is easy to block, the water quality mixing is limited by the water distributor, the short flow or uneven mixing is easy to cause, the treatment efficiency is reduced, the stirring is insufficient, the mass transfer efficiency is low, and the treatment efficiency is not high.
The technical problem that current UASB system exists lies in: the common UASB is sensitive to sudden change of water quality and load, the impact resistance is poor, short flow phenomenon is easily caused under the condition of low ascending flow velocity, the processing capacity is influenced, and the discharged water is easy to run mud under the condition of high ascending flow velocity.
AO is the abbreviation of anaerobic Oxic, AO process is also called facultative aerobic process, A (anaerobic) is facultative section, use and denitrify and dephosphorize; o (oxic) is an aerobic section for removing organic matter from water. Its advantages are that it not only degrades organic pollutant, but also has a certain function of removing nitrogen and phosphorus, and uses anaerobic hydrolysis technology as pretreatment, so the AO method is an improved activated sludge method.
The principle is that an AO process connects an anoxic section at the front section and an aerobic section at the rear section in series, DO at the A section is not more than 0.2 mg/L, DO at the O section is 2-4 mg/L, heterotrophic bacteria at the anoxic section hydrolyze suspended pollutants such as starch, fiber, carbohydrate and the like and soluble organic matters into organic acid so that macromolecular organic matters are decomposed into micromolecular organic matters, insoluble organic matters are converted into soluble organic matters, when the products after anoxic hydrolysis enter an aerobic tank for aerobic treatment, the biodegradability and the oxygen efficiency of sewage can be improved, and the heterotrophic bacteria at the anoxic section ammoniate pollutants such as protein, fat and the like (N on an organic chain or amino in amino acid) to free ammonia (NH)3、NH4+) Under the condition of sufficient oxygen supply, the nitrification of autotrophic bacteria can react NH3-N (NH4+) Oxidation to NO3-Returning to the A pool through reflux control, and under the anoxic condition, carrying out denitrification on the heterotrophic bacteria to obtain NO3-Reduced to molecular nitrogen (N)2) C, N, O, the ecological cycle is completed, and the sewage harmless treatment is realized.
The technical problems of the existing AO process systems are as follows: the reflux amount of the nitrifying liquid is changed along with the concentration of ammonia nitrogen, and generally the reflux is not large, so that the toxic substances are difficult to achieve the detoxification function.
