Description
Technical field
The present invention relates to technical field of sewage, a kind of three ranks O/A decentralized type sewages processing one makeup is particularly related to
Put and method.
Background technology
China is agricultural population big country, and rural area is vast, and substantial amounts of sanitary sewage is produced daily, and village lacks mostly
Special sewage collecting treatment facility, only part resident family have septic tank or methane-generating pit processing system and sanitary sewage are carried out simply
Precipitation and fermentation process, most of resident do not carry out handling just directly discharge to sanitary sewage, domestic sewage in rural areas into
For the another severe contamination source of water pollution.Domestic sewage in rural areas pollution sources, which have, is distributed scattered, wide, amount less and not easily collecting
The features such as, it is not suitable for laying sewage collecting pipe network on a large scale and domestic sewage in rural areas is included into large-scale centralized sewage treatment plant is collected
Middle processing, therefore, to increase rural domestic sewage treatment coverage rate, improves rural domestic sewage treatment rate, research and development investment
Less, process equipment simple and flexible, energy consumption be low, efficiency high, operation maintenance are conveniently suitable for the sewage water treatment method in rural area and set
It is standby significant.
Through retrieval, also there are some to be disclosed on the technical scheme of rural sewage treatment at present, such as：Chinese patent
CN104176880A provides a kind of plural serial stage modularization domestic sewage processing system and domestic sewage processing method, multistage string
Grid pond, sedimentation basin, anaerobic pond and oxygen filtering ponds, the level that gang mould block domestic sewage processing system includes being sequentially connected in series are dived
Artificial wetland, vertical subsurface flow wetland and discharge bay, good sewage processing effect, it is adaptable to the relatively low rural area of the density of population
Area, but for the place without natural resources such as marshland, waste and old river course, grassplot, forest lands, the sewage disposal system in the invention
System will be subject to certain restrictions.
The content of the invention
The present invention utilizes the existing of rural area to overcome the shortcomings of that rural sewage treatment cost is high and lacks maintenance management
Condition, with reference to the low mandruka filler of cost, there is provided a kind of three ranks O/A decentralized type sewages processing integrated apparatus and method.
The device includes water inlet system, three O/A processing ponds, aerating system, biofilm filtration and processing system, goes out water system
System；Water inlet system includes water inlet pipe, water pump, and three O/A processing ponds are respectively single order O/A processing ponds, second order O/A processing ponds and three
Rank O/A processing ponds, aerating system includes air blower, aeration valve, air inlet pipe, micropore aeration pipe, biofilm filtration and processing system
Including perforated sludge discharge pipe, stainless steel refined net support and biomembrane sponge filler；Outlet system includes total delivery port and effluent weir；
Sewage enters the aerobic zone of single order O/A processing ponds by water pump in water inlet pipe, and air blower is by air inlet pipe by air
Send into three O/A processing ponds, air inlet pipe to set in aeration valve, three O/A processing ponds and be separated into by biomembrane sponge filler
Aerobic zone and anoxic zone, micropore aeration pipe and perforated sludge discharge pipe are located at aerobic zone, and biomembrane sponge filler uses stainless steel fine-structure mesh
Lattice support is fixed, and total delivery port, which is located inside three rank O/A processing pond upper ends, total delivery port, sets effluent weir.
Wherein, biomembrane sponge filler be tabular sponge filler, be fixed using stainless steel refined net support, prevent because
Water impact causes filler to deform, and biomembrane sponge filler with ground as 45 °~60 ° angles to be individually fixed at three O/A
Manage in pond.On the one hand biomembrane sponge filler retains and precipitates the suspension and particulate organic matter in sewage, on the other hand, in sea
The biomembrane formed on continuous filler plays a part of the pollutants such as organic matter, the nitrogen phosphorus in further degraded sewage.To ensure
Water water quality, periodically takes out pollution sponge, cleans up, reusable, and cleaning waste water is handled using the device.
Micropore aeration pipe in three O/A processing ponds makes the dissolved oxygen of aerobic zone be maintained at 0.5-2.0mg/l concentration levels.
The method that integrated apparatus is handled using the three ranks O/A decentralized type sewages, comprises the following steps：
S1：Pending sewage, into single order O/A processing ponds, is precipitated via water pump lifting to sewage, biomembrane mistake
Filter, aerobic and anoxic biological treatment；
S2：The sewage handled by S1 enters second order O/A processing ponds in the mode of flowing automatically, and secondary precipitation, life are carried out to sewage
Thing membrane filtration, aerobic and anoxic biological treatment；
S3：Enter three rank O/A processing ponds by the S2 sewage handled, repeat S1 and S2 processing procedure, finally the row of satisfaction
The water for putting standard is discharged by total delivery port.
The above-mentioned technical proposal of the present invention has the beneficial effect that：
(1) three rank O/A decentralized type sewages handle integrated apparatus, and tabular mandruka filler is set in O/A reaction tanks,
Play a part of trapped particles thing and suspension, while aerobic and two kinds of environment of anoxic can also be created in same processing pond, it is real
Existing synchronous nitration and denitrification process；
(2) three rank O/A decentralized type sewages handle integrated apparatus, and culture generation is biological on plate-like porous sponge filler
Film, can the further pollutant such as degradation of organic substances, nitrogen phosphorus, make it have the effect of biofilter；
(3) three rank O/A decentralized type sewages of the invention processing integrated apparatus, without setting return-flow system, equipment operation
Simply, operation maintenance requirement is few, and operating cost is low.
