Description
Technical field
The present invention relates to a kind of sewage treatment project fields of living environment, and in particular to a kind of dispersant type domestic wastewater pipe
The filtration system in road.
Background technique
The dispersant type domestic wastewater in China is primarily referred to as the rural resident in no town sewage pipe network area, Peasants Joy, villages and small towns
A small amount of sanitary sewage of the generations such as restaurant.There are yields that few, water less (is generally not more than 2m for dispersant type domestic wastewater3/
Family day) and sewage generate the intermittent time it is not equal the problems such as, current decentralized type sewage processing technique mainly with small-sized aeration tank,
Based on the buried aerobic equipment of underground powerless purifying processing device, artificial swamp, integral type, anaerobic filter etc..
1., small-sized aeration tank be early stage sewage disposal technology, various types of filler can be added in aeration tank, also Suspensible
Polymer carrier.Since the small water sewage effect of the technical treatment is poor, maintenance operation is costly, infrastructure costs also compared with
Height, therefore, application is few at present.
2., underground powerless purifying processing device, be on the basis of facultative filter tank develop made of, treatment process
Process are as follows: sanitary sewage → anaerobic acidification → facultative filtering → ecology ditch (gravity-flow ventilation) → discharge.Maximum of technique is special at this
Point is to increase ecological ditch, and the purpose for increasing ecological ditch is to carry out oxidation processes to the sewage after anaerobic fermentation, makes effluent quality
It further increases, but since ecological ditch is nature oxygenation, effect and common septic tank effect are similar, and invest being much higher than
Manure pit, therefore use less.The technical solution is more complex, and basis is costly.Effluent quality is preferable.
3., artificial swamp, be always the research emphasis of dispersant type domestic wastewater processing technique, common artificial swamp has ground
Table cross flow formula, undercurrent type.The effluent quality of artificial swamp is good, and removal efficiency of nitrogen and phosphorus is higher, but build it is more complex, the selection of plant and
Management needs certain professional technique, causes blockages running 2~3 Nian Houyi.
4., the buried sewage disposal device of integral type, be the decentralized type sewage processing technique that developed recently gets up.The equipment will
Polymer carrier is placed in cesspool, may be configured as A/O working method, is not take up surface soil, there is good afforestation effect,
Effluent quality is good, but need to continue to provide water pump, blower power, and operating cost is higher.
5., percolation type sewage disposal technology be also adapted for the technology of decentralized type sewage processing, sewage is by continuous filter
The fillers such as sand, steel slag, rubble, are purified from top to bottom.The technology effluent quality is good, and power consumption is low, operation and maintenance letter
It is single, but need to occupy certain soil.
Therefore, characteristic that is small for dispersant type domestic wastewater water, going out water unstable, which designs a kind of operation process, simply to be had
Effect, the small duct type filtration system of land seizure be very it is necessary to.
