The device has the advantages of simple and reasonable treatment process, convenient operation, good treatment effect, low treatment cost, no secondary pollution, and mature and reliable hardware facilities and technological process.
Description
Technical field
The utility model belongs to the waste disposal plant field, is specifically related to a kind of higherly relatively for COD and ammonia nitrogen, and the relatively poor sewage of biochemical has the device of the high sewage of the processing COD of good effect of removing and ammonia-nitrogen content.
Background technology
Present sewage water treatment method mainly contains conventional activated sludge method, A/O method, oxidation ditch process and SBR method, aforesaid method is applicable to various forms of sewage disposals, but higher relatively for COD and ammonia nitrogen, can the relatively poor sewage of biochemical row, from the treatment effect that is difficult to aforesaid method reach good.
The utility model content
The purpose of this utility model is to provide a kind of treatment scheme advantages of simple, and operation is convenient, and treatment effect is good, low, the non-secondary pollution of processing cost, and the device of the high sewage of the processing COD of its hardware facility and the equal mature and reliable of technical process and ammonia-nitrogen content.
The utility model is achieved through the following technical solutions:
Be the device of the high sewage of a kind of COD of processing and ammonia-nitrogen content, it is characterized in that comprising the hydrolysis acidification pool, anaerobic pond, anoxic pond, Aerobic Pond, the settling tank that connect successively.
Described hydrolysis acidification pool is connected with water inlet pipe, blowdown pipe, and Aerobic Pond is connected with gas blower, and settling tank is connected with blow-off pipe with rising pipe.
Be provided with the mixed-liquor return pipe between Aerobic Pond and the anoxic pond.
Be provided with reflux sludge tube between settling tank and hydrolysis acidification pool, the anaerobic pond.
The mixed-liquor return pipe is provided with the mixed-liquor return pump.
Reflux sludge tube is provided with sludge reflux pump.
Principle of work of the present utility model is as follows:
At first enter in the hydrolysis acidification pool through pretreated sewage by water inlet pipe, particulate matter during a large amount of microorganisms will be intake and colloidalmaterial are held back rapidly and are adsorbed, the material that is retained down is adsorbed on the surface of hydrolyzing sludge, the metabolism that is decomposed at leisure, it is greater than hydraulic detention time at intrasystem sludge retention time.Under the effect of a large amount of hydrolytic bacterias, with insoluble hydrolysis of organic matter is dissolved matter, simultaneously under the synergy of acid-producing bacteria, with macromolecular substance, be difficult to biodegradable material and be converted into and be easy to biodegradable small-molecule substance, again be discharged in the liquid, under higher hydraulic load, flow out hydrolysis acidification pool with water and enter anaerobic pond, anoxic pond, Aerobic Pond successively, sewage carries out the denitrification denitrogenation process in anoxic pond with after the mixed solution of internal reflux mixes, in Aerobic Pond organic pollutant is carried out further oxygenolysis.The mud part that settling tank precipitates by reflux sludge tube be back to hydrolysis acidification pool, anaerobic pond carries out the release of phosphorus.
The utlity model has following beneficial effect:
(1) technical process is simple, and total hrt is also shorter, and does not need additional carbon, and working cost is lower.
(2) because the existence of hydrolytic tank is arranged, can improve the biodegradability of sewage, reduce follow-up biochemical treatment load.
(3) can reach the purpose of removing organism and denitrogenation dephosphorizing simultaneously.
(4) thread fungus is difficult for growth and breeding, does not therefore have the sludge bulking problem basically.
The utility model utilizes " hydrolysis+anaerobism+anoxic+aerobic " Technology of Sewage can reach the good treatment effect.Utilize the utility model can solve numerous sewage disposal plant effluent COD and ammonia nitrogen instability and higher problem, market outlook are very wide.The utility model can be widely used in handling municipal wastewater and industrial sewage field, industrial park.
