Description
Technical field
The present invention relates to integral domestic sewage treatment device, belong to water-treatment technology field.
Background technology
According to " 12 " whole nation urban wastewater treatment and the planning of regeneration Facilities Construction, by 2015, sewage disposal
Rate improves further, and treatment rate of domestic sewage reaches 85%(municipality directly under the Central Government, provincial capital and cities specifically designated in the state plan city, and to realize sewage complete
Portion collects and processes, prefecture-level city 85%, county-level city 70%), county town wastewater treatment rate averagely reaches 70%, newly-increased sewage disposal scale
4569 ten thousand steres/day.As can be seen here, the requirement increasingly stringent to wastewater treatment rate for the country.And with China's urban population
Increase sharply, cities and towns water requirement is drastically incremented by, corresponding sewage quantity is also drastically incremented by.
The facility processing sewage at present mainly has down-stream processing system and middle and small scale decentralized type sewage processing system.
Integral domestic sewage treatment device belongs to middle and small scale decentralized type sewage processing system.Compared with down-stream processing system,
It is excellent that integral domestic sewage treatment device has that treatment effeciency is high, energy consumption is low, sludge output is few, convenient management, floor space are little etc.
Point.Therefore, integration apparatus are widely applied in sewage treatment area, form complementation with down-stream processing system, and
And in the new situation, compared to down-stream processing system, with more irreplaceable advantage:
Make full use of funds lying idle in society；
(2) alleviate the pressure of municipal pipe network construction；
(3) effectively save construction area；
(4) Treated sewage reusing, using water wisely are effectively realized.
At present, the problem that the like product of integral domestic sewage treatment device is primarily present has:
1. blower fan power consumption is big, aerator is fragile, blocking, change difficult.Main cause is:
A. adopt the aeration tube aeration that micro-hole aerator or " non-" font connect, Qian Zhecun the aerating pipelines of like product more
Easily block, wear and tear, changing the problems such as frequent, air local flow resistance is big in aeration head, the latter, in actual motion, works as aeration
After blower fan cuts out, the internal sludge reflux of aerating pipelines, it is deposited on ttom of pipe, after reopening blower fan, a part of mud can be with air
Outside effuser, but still mud is had to be extruded into ttom of pipe, under the washing away of continuous fresh air, gradually mummification, consolidation and ttom of pipe.Blower fan opens
After stopping repeatedly, ttom of pipe forms stabilized sludge layer, blocking pipeline, reduces circulation area, increases wind speed and flow resistance；
B. adopt uniform aeration mode like product, aeration rate prolongs water (flow) direction and is uniformly distributed, and is also easy to produce OTR more
Problem low, that blower fan power consumption is big.Because, in sewage disposal process, pollutant levels and required aeration rate are gradually lowered, and uniform
Aeration mode will produce anterior aeration rate deficiency, and dissolved oxygen concentration is low, and rear portion aeration rate is had more than needed, the high phenomenon of dissolved oxygen concentration,
Cause Fan Selection excessive, the high problem of blower fan power consumption.
2. run in foam flash, effluent quality unstable.Main cause is: product master sewage to be processed is life
Sewage, compared with municipal sewage plant, sewage quantity is little, and the pollutant component of daily different periods changes greatly, particularly cleans
In Phosphorus From Wastewater element, food and drink waste water, ammonia and nitrogen components change greatly, cause effluent quality unstable.And, in aeration process, easily
Produce foam, overflow at manhole, affect equipment appearance and service life.
Content of the invention
Above-mentioned in order to solve the problems, such as, it is an object of the invention to provide integral domestic sewage treatment device.
