Description
Technical field
The invention belongs to environmental engineering, restoration of the ecosystem engineering and hydro project technical field, refer in particular to 3 D multi-directional stream wetland and handle the method that enters rivers pollution of area source and purifying river water.
Background technology
At present, utilize natural water soil resources such as irrigation canals and ditches river, pool, wasteland to handle effluent sewage both at home and abroad and adopt three kinds of methods: artificial swamp method, oxidation pond method and soil filter method.
Artificial swamp is a kind of ecological pollution treatment technology of having applied both at home and abroad for many years.In the prior art, relatively large artificial swamp generally all is with multistage series-parallel system combination.For the combination of the wetland of serial arrangement, past is general, and that all adopts is undercurrent, goes up downward stream mode, and promptly a unit flows under water, and a unit stream waterborne trickles repeatedly.Most of method that makes sewage modify the pool successively through settling tank, plug-flow bed, down flow artificial wet field, up stream artificial swamp and water quality that adopts, thereby sewage is purified, wherein, the current in plug-flow bed, down flow artificial wet field and the up stream artificial swamp are undercurrent.Though existing artificial swamp can be realized the ecological management to sewage, it is big to exist floor space, the little easy obstruction of aquifer yield, inefficient problem.
Oxidation pond also claims biological pond, stabilization pond, and the existence difference by pool water oxygen can be divided into the aerobic pool, anaerobic pond, the facultative oxidation pool, aeration oxidation pond.Have by anaerobic pond-the hold concurrently oxidation pond system handles sewage that the oxygen pool-the aerobic pool is formed and to reduce investment outlay, to save energy consumption and to manage advantages such as simple." food chain " of mutual coordination on the double oxygen pool, the corresponding foster duck in the aerobic pool, breed fish or some waterplant, set up in the biological oxidation pool of China exploitation in whole oxidation pond system, the raising wastewater treatment efficiency is considered to have the technology of using value.But the natural oxidation pool is handled high concentrated organic wastewater and is had low, the weak effect of processing power, and floor space is big, produces shortcomings such as stench and treatment time length.
The polluted water land treatment system is under manually operated condition, sewage is batched on the soil, by soil one botanical system, carry out a series of physics, chemistry, physical chemistry and biochemical scavenging process, a kind of sewage treatment process that sewage is purified.Mainly contain quick percolation treatment system and underground sewage percolating treatment system.The polluted water land treatment system compare with other dirty water living creature processing technique have reduced investment, energy-conservation, advantage such as working cost is low.The subject matter that exists is that hydraulic load is low, processing power is low and floor space is big.
More than these methods except some limitation of inherent separately, all can not adapt in addition the rivers Large Water variation, can not adapt to the two-way and multidirectional variation of river waterflow and be difficult to adapt to the variation of the temperature difference throughout the year.
Summary of the invention
The objective of the invention is to fully excavate the staggered band in rivers land and water---the environmental ecology potential of wet land system, based on the staggered band in rivers land and water---wet land system, set up reduced investment, effective, management less, view is beautiful and the method for river land, the shore staggered band structure 3 D multi-directional stream wetland easily promoted, plays the effect of handling effluent sewage, ecological revetment, beautifying view, Wetland ecological reparation and resource circulation utilization.
