Description

A kind of small-sized anniversary composite purification system that utilizes the Herba Eichhorniae purifying domestic sewage
Technical field
The present invention relates to a kind of purifying domestic sewage and innoxious blowdown system, also can be used as the advanced treatment of municipal sewage plant second-stage treatment discharging water outlet, specifically a kind of small-sized anniversary composite purification system that utilizes the Herba Eichhorniae purifying domestic sewage.
Background technology
Along with the sustainable development of urbanization progress, the city size Rapid Expansion, new samll cities and towns continue to bring out, and handle to municipal wastewater and bring very hang-up.Some samll cities and towns are because small scale, and financial burden is big, are difficult to covered by the WWT pipe network, and it is commonplace that sewage arbitrarily enters the phenomenon in river course; Though large size city continues to increase input aspect WWT, often only can reach the second-stage treatment emission standards to municipal wastewater, the advanced treatment of sewage is because technical requirements and cost are high, and is still difficult at present by universal.According to national standard, in the sewage of municipal wastewater treatment plant second-stage treatment, still contain 0.5-1 mg L -1Full phosphorus, 30 mg L -1Nitrate salt, concentrations of nutrient is still higher.This present situation brings very big threat for the fragile aquatic ecosystem of China.
Because China's size of population is big, live and concentrate, big to the pressure of environment, make that the environmental capacity of aquatic ecosystem is little, relatively more responsive to input with nutrient essence such as materials such as N, P.It is reported that in the lake, content of tatal phosphorus reaches 0.05 mg L -1Just be enough to cause the outburst of wawter bloom.According to the statistics of national environmental protection portion, the adjacent small-sized lake pollution in China and cities and towns is serious, and water quality such as large-size lake such as Dian Chi, Taihu Lake also allow of no optimist, and the lake eutrophication area still has increase trend.The water quality deterioration in these lakes brings threat for local water resources safety, algal bloom even generate a panic for some geographic Drinking water supplies.
Municipal wastewaters high with cost requirement to the advanced treatment of municipal wastewater second-stage treatment plant effluent technology, samll cities and towns are handled the problem of difficulty; Carried out a large amount of research both at home and abroad; Wherein, The artificial swamp technology is considered to a kind of low cost, municipal wastewater treatment system efficiently, is recommended by United Nations.Limit the very big reason that this technology popularizes and be, this technology mainly relies on the nitrogen of the effect of wetland plant and soil microorganisms in purifying waste water, and through plant absorbing and precipitating action dephosphorization, these processes depend on the local climate condition; In addition, for surperficial flow pattern artificial swamp, be prone to grow problems such as mosquitos and flies; And for subsurface constructed wetland, then be prone to cause stop up.China has also carried out a large amount of research aspect artificial swamp, and has set up some exemplary artificial wet land systems, and once the floating material of floating bed technique-a kind of utilization is carried plant; Make floating plant at the sewage water surface, utilize a large amount of research of the absorption of plant and the technology of root table microbially decontaminate sewage-carried out, above problem is had overcoming to a certain degree; But; How to overcome the restriction of weather condition, improve the purification efficiency aspect of wet land system, still report is less.Municipal wastewater purification system anniversary last effect based on wetland technology is poor, and efficient is low.On the other hand, the growth of wetland plant is the efficient important mechanisms of removing of nutritive salt in the sewage, therefore how to handle the wetland plant body of raised growth results, also is a big factor of restriction wet land system.Research in China person attempts to draw municipal wastewater as the water planting nutrition source through utilizing cash crop water planting pattern, realizes that the purification and the resource utilization of sewage combines, and solves the problem of wetland plant body how to handle the raised growth results.Wherein, mainly be rye grass by what extensively adopt, still, be the agricultural-food supply the market of nutrition source water planting with the municipal wastewater, even there is not the pollutent problem that exceeds standard, on consumer psychology, often also be difficult to accept, this approach is not really walked logical.Terrestrial plant also makes terrestrial plant aspect processing efficiency, be not so good as waterplant with respect to the deficiency of aquatic plants growth amount.And wetland plant is especially like Herba Eichhorniae, these plants of water lettuce, low to the nutrient concentration demand; Growth is that plant is removed in a kind of ideal nutritive salt absorption rapidly, but also just because growth is rapid; Plant materials is handled difficult, and more worry flows into environment and had a mind to avoid by people.Therefore, popularizing of artificial swamp technology receives the influence of two technical barriers to a great extent: how 1 overcome the weather condition restriction in low temperature season such as late autumn, early spring, winter; How 2 overcome the wetland plant body is handled a difficult problem.
Municipal wastewater is rich in the nutritive salt this point and is concerned by people always, yet because the popularizing of cities and towns bathroom facility, even make that harmful substance contents is very low in the municipal wastewater, also because nutrient concentration is low excessively, agricultural value is little, and is difficult to really used by agriculture field.Both at home and abroad to the plain recovery of phosphorus in the municipal secondary treatment process; Carried out big quantity research, wherein reclaimed the phosphorus element, set up technological line in theory through producing struvite; The success of achieving success experimental scale; But at the lower municipal secondary effluent of relative concentration, reach the plain recovery aspect of common life phosphor in sewage to how, do not report at present.The phosphorus of this type sewage reclaims, and can adopt anionite-exchange resin to carry out in theory, but on cost, often has any problem, and this also is the difficult reason of popularizing of municipal tertiary treatment.
In sum; At present aspect the municipal wastewater processing; Especially the deep purifying problem of municipal sewage plant's second-stage treatment, not by the aspects such as resource utilization recovery of nutritive salt in the sanitary sewage disposal of municipal wastewater pipe network coverage area, the sewage, lack economical and technical all feasible technical solution scheme.
