Description

A kind of complex ecological filter tank and treatment process thereof of handling sanitary sewage
Technical field
The present invention is a kind of, and what handle that the complex ecological filter tank of sanitary sewage and treatment process thereof relate to is a kind of complex ecological filter tank facility of handling domestic sewage in rural areas by using; belong to environment protection and improvement field; be a kind of complex ecological purification techniques that utilizes, handle the large-scale treatment facility that the assorted in a large number draining in Rural areas comprises life, agriculture production tail water.
Background technology
The more ecological purification processing mode of domestic domestic sewage in rural areas by using subsequent disposal utilization has artificial swamp tupe and stabilization pond tupe.
These technology have had utilization to a certain degree in the rural area, obtained wastewater purifying efficiency preferably, but exist certain problem, and are more much higher than traditional technology as artificial swamp technology floor space, and the variation of seasonal factor has also limited the development of wetland.
Stabilization pond is handled sewage by the helotism system, and the aerobic pool, anaerobic pond, facultative lagoon, aeration lagoon, ecological pond several types are arranged.It is a kind of treatment of Organic Wastewater pond, also has some shortcomings, and is too much as floor space, and it is bigger that decontamination effect improving is influenced by natural causes such as temperature, wind-force, if design or operational management are improper, can cause seepage, forms secondary pollution.Will regularly carry out artificial desilting at the bottom of the pool simultaneously, clear the pollution off, operation takes time and effort.
In order to remedy the weak point of artificial swamp tupe and stabilization pond tupe, need a kind of new more intensive, more stable sewage ecological purification tupe of exploitation.
In addition, a lot of rural areas of China are based on concentration of local and relative dispersive inhabitation pattern, and sanitary sewage is many just directly to enter natural water through the three-grid septic tank simple process, causes the body eutrophication of rural settlements's periphery serious., a kind ofly concentrate among a small circle, floor space is little, capital cost and running cost advanced treatment of wastewater technology lower, that be easy to safeguard press for and develop through the random contamination phenomenon that causes of row of preliminary treatment sewage at the rural area.
