Description
Technical field
The utility model relates to sewage treatment unit, belongs to water-treatment technology field.
Background technology
According to " 12 " national urban wastewater treatment and the planning of regeneration Facilities Construction, by 2015, wastewater treatment rate improves further, treatment rate of domestic sewage reaches 85%(municipality directly under the Central Government, provincial capital and municipalities and cities with independent plans city and realizes sewage and all collect and process, prefecture-level city 85%, county-level city 70%), county town wastewater treatment rate on average reaches 70%, newly-increased sewage disposal scale 4569 ten thousand steres/day.As can be seen here, the requirement increasingly stringent of country to wastewater treatment rate.And along with China's urban population increases sharply, cities and towns water requirement sharply increases progressively, and corresponding sewage quantity also sharply increases progressively.
The facility of disposing of sewage at present mainly contains down-stream treatment system and middle and small scale decentralized type sewage treatment system.Integral domestic sewage treatment device belongs to middle and small scale decentralized type sewage treatment system.Compared with down-stream treatment system, integral domestic sewage treatment device has the advantages such as processing efficiency is high, energy consumption is low, sludge output is few, convenient management, floor space are little.Therefore, integration apparatus is applied widely at sewage treatment area, forms complementation with down-stream treatment system, and in the new situation, compared to down-stream treatment system, has more irreplaceable advantage:
Make full use of funds lying idle in society;
(2) pressure of municipal pipe network construction is alleviated;
(3) construction area is effectively saved;
(4) effectively Treated sewage reusing is realized, water saving.
At present, the main Problems existing of the like product of integral domestic sewage treatment device has:
1. blower fan power consumption is large, and aerating apparatus is fragile, blocking, change difficulty.Major cause is:
A. aerating pipelines many employings micro-hole aerator of like product or the aeration tube aeration of " non-" font connection, there is aeration head and easily block, wear and tear, change the problems such as frequent, air local flow resistance is large in the former, the latter is in actual motion, after Aeration fan is closed, the inner sludge reflux of aerating pipelines, be deposited at the bottom of pipe, after reopening blower fan, part mud can with outside air outlet pipe, but still have mud to be extruded at the bottom of pipe, under the washing away of continuous new wind, mummification gradually, at the bottom of consolidation and pipe.After blower fan start and stop repeatedly, form stabilized sludge layer at the bottom of pipe, blocking pipeline, reduce circulation area, increase wind speed and resistance to flow;
B. like product many employings uniform aeration mode, aeration rate prolongs water (flow) direction and is uniformly distributed, and easily produces the problem that oxygen transfer rate is low, blower fan power consumption is large.Due in sewage treatment process, Pollutant levels and required aeration rate reduce gradually, and uniform aeration mode will produce anterior aeration rate deficiency, dissolved oxygen concentration is low, and rear portion aeration rate is had more than needed, the phenomenon that dissolved oxygen concentration is high, cause Fan Selection excessive, the problem that blower fan power consumption is high.
2. in running, foam flashes, effluent quality is unstable.Major cause is: product master sewage to be processed is sanitary sewage, compared with municipal sewage plant, sewage quantity is little, and every day, the pollutant component of Different periods changed greatly, particularly in Cleaning Wastewater, in phosphoric, food and drink waste water, ammonia and nitrogen components change greatly, causes effluent quality unstable.Further, in aeration process, easily produce foam, overflow from manhole, affect equipment appearance and work-ing life.
Summary of the invention
In order to solve the above problems, the purpose of this utility model is to provide sewage treatment unit.
The utility model patent adopts following technical scheme:
Sewage treatment unit, comprises casing, has hydrolysis acidification pool in casing, one-level biochemistry pool and secondary biochemical pond; Water inlet component is communicated with the top of hydrolysis acidification pool, the bottom of hydrolysis acidification pool is communicated with the bottom of one-level biochemistry pool, the bottom of one-level biochemistry pool is communicated with the bottom in secondary biochemical pond, the top in secondary biochemical pond is communicated with the bottom of settling tank by pipeline, the top of settling tank is communicated with the top of sterilization pool, the bottom of settling tank is communicated with sludge pump, pipeline communication is passed through on the top of sludge pump and sludge sump, the top of sludge sump and the top of hydrolysis acidification pool, by pipeline communication, have Aeration fan in fan house; The top in one-level biochemistry pool and secondary biochemical pond is fixed with shower; The bottom in one-level biochemistry pool and secondary biochemical pond has aerating apparatus; Aerating apparatus comprises aeration supervisor, elbow and aeration branch pipe; Aeration is responsible for; Aeration supervisor installs 1 ~ 2 elbow in bottom, installs aeration branch pipe between two elbows; The aeration of the bottom in the air outlet of Aeration fan and one-level biochemistry pool and secondary biochemical pond is responsible for and is communicated with, and the top in one-level biochemistry pool and secondary biochemical pond has shower; The inside in one-level biochemistry pool and secondary biochemical pond has Aerobic Pond filler assembly and aerating apparatus, and the opposite side of casing has ventilation hole, the inwall of settling tank has water outlet cofferdam; Have inclined tube filler assembly and cloth water assembly in settling tank, the top of sterilization pool is communicated with outlet component.
