Description
Technical field
The utility model relates to technical field of water body purification, particularly a kind of novel artificial wet land system based on evenly flowing to.
Background technology
Artificial swamp is a kind of Novel sewage treatment technology that 20 century 70s rise, because it has, buffer capacity is large, convenient management, technique are simple, reduced investment, working cost are low, environmental benefit high, is widely used in the sewage disposal of samll cities and towns and Rural areas.Artificial swamp refers to the simulation of people to natural wetland system, utilizes ecological method to remove pollutent, to reach the object of purifying waste water.Artificial swamp is the ground similar with swampland by artificial construction and controlling run, sewage, mud there is the dosing of control on the artificial wetland built, sewage and mud are in the process flowed in a certain direction, mainly utilize soil, artificial dielectric, plant, the physics of microorganism, chemistry, biological triple synergy, to a kind of technology that sewage, mud process.Its mechanism of action comprises absorption, delay, filtration, redox, precipitation, microbial decomposition, conversion, plant are covered, the effect of residue accumulated, water transpiration and nutrition absorption and all kinds of animal.
Conventional artificial swamp, often lays soil on upper strata, but with weed seed, can be easy to grow weeds, form competitive relation, be unfavorable for the growth of plant with the plant of artificial growth in soil; And the particle of soil is less, is easily taken away by liquid, through the hole of each layer, finally arrive water outlet pipe part, blocking water pipe; The sewage also passed in oriented artificial swamp, the various chemical element content of mud are more, easily cause the crumb structure of soil to be destroyed, cause the water conservation of soil, fertilizer-preserving ability and permeability to reduce, cause soil compaction, be unfavorable for plant-growth, affect the effect of Constructed Wetland For Purifying water body.And if be full gravel or/and rubble, the suitable needs of the size of top layer plant growing layer and the Thickness Ratio of each layer are studied further, not only will be conducive to plant-growth, but also will ensure that gravel can not meticulous blocking water pipe.
Artificial marsh sewage treatment system it can effectively process diversified waste water, as sanitary sewage, trade effluent, percolate, surface runoff rainwater, combined system water drain stormwater overflow water etc.Add up according to investigations, have the wet land system of up to ten thousand Treating Municipal Sewage and various industrial sewage in steady running in Europe and North America, the number of sewage treating artificial wet land other area application in the world is also increasing sharply.
There is the defect that entirety can not move, water purification is uneven, soil is easily brought into water outlet pipe part blocking water pipe in prior art; This has seriously restricted its promotion and application at sewage treatment area; The waterflood system of existing artificial swamp only has one or two, is mostly all in an orientation, can not provides uniformly, also causes the decontamination effect improving of the decontamination effect improving near water outlet and water outlet distant place inconsistent, affects decontamination effect improving.
