Description
Technical field
This utility model belongs to technical field of sewage treatment equipment, more particularly to a kind of sewage disposal system.
Background technology
China always payes attention to Water Pollution, in recent years, achieves very big effect, and quality of water environment has changed
Kind, but it is still severe to have problems.It is mainly manifested in, city concentrated contaminated water source is paid attention to and administered, concentrates in city and build
A certain degree of improvement is obtained into area's water environment, early-stage rainwater has been changed into by point-source pollution to the main pollution of water body at present dirty
Dye, widespread pollution from the overuse of fertilizers and pesticides in rural area and the pollution of rural scattered domestic sewage.
Rural Water Pollution thing discharge capacity remains high-order, accounts for more than the 50% of national Sewage Water Emissions amount, and due to rural area
, away from urban pipe network, collection sewage conduct cost performance is low, is affected by fund, and handling rate is low, mainly adopts at present for sanitary sewage
With the process of decentralized type sewage processing meanss.

Reason is affected by rural population Out-migrant for work etc., and population fluctuation's property is big, and festivals or holidays population is more, and permanent resident population is few at ordinary times, place
Reason device will adapt to the different water yields and require, its anti-undulatory property be required higher.
Using activated sludge method processing technique (such as A/O methods, A/A/O methods, biological contact oxidation process, MBR methods etc.), due to
Sewage quantity is unstable, and design load is low at ordinary times, it is difficult to form sufficient concentrations of biological sludge, and treatment effect cannot ensure, portion
After separating device comes into operation, in idle state.
Using biomembrance process handling process (biofilter, land percolation etc.), although improve the adaptation to sewage quantity
Property, but generally take up an area larger, and there is system easily, have impact on application.
Using techniques such as artificial swamp, oxidation pond, capacity of resisting impact load is poor, and treatment effect is by factors such as temperature, rainfalls
Affect, effect is unstable, and take up an area very greatly, exploitativeness is poor.
In view of current current situation and existing problems of part rural sewage treatment technology, the research and development of new technique mainly should consider
Solve following problem：
1) adapt to country sewage water quality, the characteristics of water yield undulatory property is larger, can be at holding under the different water yields, water quality
Reason effect stability.
2) by effect of natural conditions is little, maintenance management workload is little, fault rate is low, can the operation of long-time automatic stabilisation, remain
Remaining sludge quantity is little.
3) invest little, operating cost low, reduce the financial burden that builds and run.
4) occupation of land is little, and exploitativeness is strong.
