Description
Technical field
The utility model belongs to technical field of sewage, be specifically related to a kind of simple in structurely, technical process is easy, and soil physico-chemical property is better improved, prevent that the land treatment system upper layer of soil from stopping up, the ecological filling-material structure of the artificial soil Sewage treatment systems of efficient dephosphorization.
Background technology
Along with high development of social economy, people's environmental protection consciousness progressively strengthens.The source of sewage of rural area, city suburbs and motorway satellite regions can't be incorporated municipal sewage pipe network into because of high dispersing and handles, and often directly externally discharging has had a strong impact on surrounding enviroment.Especially the sewage in some rivers, lake, extra large peripheral village enters river course, lake especially directly or indirectly, causes natural water to pollute, and causes many lake eutrophications serious, a large amount of hydrobiont death.The water body of severe contamination has influenced people's ordinary production, life.But these sewage are often away from municipal sewage pipe network, and centralized collection pipe network cost is too high, build sewage works operation maintenance inconvenience on the spot, and cost are too high.Therefore, seek a kind of low cost, high-level efficiency, the sewage disposal mode that is suitable for the high dispersing polluted source is the present technical issues that need to address.
Artificial land treatment system has unique advantages aspect the processing dispersion type domestic wastewater, can effectively remove BOD, COD, SS, ammonia nitrogen, phosphorus etc., and build flexibly, cost is lower, operational management is simple, free from extraneous odour, build up and then can not have a negative impact to surrounding environment, just used more and more.Artificial land treatment system is to the purification of sewage, rely on plant the absorbing of planting in the artificial soil on the one hand to pollutent, absorption by soil on the other hand, hold back filtering contaminants matter, main then is the microorganism that utilizes wherein, promptly pollutent is decomposed, transforms, pollutent is removed by the effect of aerobic, the oxygen of holding concurrently, anaerobion.The removal of phosphorus mainly relies on the adsorption of filler in the artificial soil, and only account for about 20% by the amount of plant absorbing and microorganism absorption, natural soils are relatively poor to the phosphoric acid salt adsorptive power, and saturated easily, press for the ecological filler of seeking a kind of new and effective dephosphorization and make up high-efficiency artificial soil Sewage treatment systems.Because the characteristics of artificial soil Sewage treatment systems self, cause the obstruction and the aerobic zone reoxygenation deficiency of system in the operational process easily, aerobic microbiological is because of the oxygen deficiency causes active decline, do not cause wastewater treatment efficiency good even system is blocked and can not normally move.In addition, because of each regional natural soils physico-chemical property difference, be difficult to all be applicable to land treatment system.Along with the operation of system, the soil sclerosis of hardening easily, the inner slit that easily produces causes dwell time of sewage to shorten, and is difficult to guarantee treatment effect.Yunnan soil belongs to red soil, and its pH value is on the low side, is acid, and organic less, and this situation is unfavorable for the existence growth of microorganism.Therefore, the physico-chemical property of how to improve the soil prolongs the blocked time of soil, and becomes artificial land treatment system key of success for microbial growth provides good environment.
Chinese patent CN 1765769A discloses a kind of Sewage treatment systems of utilizing haydite and perlite for main stuffing.Though this method has certain treatment effect to micro-polluted water, wherein the filler degree of compactness is low, and dwell time of sewage is short, and treatment effect is not good, and does not relate to the improvement problem of soil physico-chemical property.
Chinese patent CN1583609A discloses a kind of one deck of setting up and has had permeable, the gas-pervious hollow material of the solid phosphorus function of reinforcement deamination as filler on the basis of traditional land percolation treatment process, though this method has removal effect preferably to phosphorus, but because of needs are made brick shapes with hollow material, and need to add material such as artificial zeolite, increased laid down cost.This patent is not made improvement to the physico-chemical property of soil equally, and the cavity filling layer is in the mid-way of land treatment system, to the not improvement effect of upper system that results in blockage easily, in case the upper strata is stopped up, then this Sewage treatment systems is difficult to reach treatment effect well.
The inventor is at above deficiency, developed a kind of artificial land treatment system that is suitable for, and soil physico-chemical property is improved, prevent the too fast obstruction of soil, improve the economical and practical new packing structure of phosphor-removing effect, evidence, effect is good.
The utility model content
It is a kind of simple in structure that the purpose of the utility model pin is to provide, and technical process is easy, and soil physico-chemical property is better improved, and prevents that the land treatment system upper layer of soil from stopping up, the ecological filling-material structure of the artificial soil Sewage treatment systems of efficient dephosphorization.
The purpose of this utility model is achieved in that and comprises plantation layer, water distribution layer, reoxygenation layer and catchment layer and distribution successively from top to bottom; Described water distribution layer is provided with the haydite layer, between described water distribution layer and the reoxygenation layer dephosphorization layer is set, and is mixed with ecological filler respectively equably in described reoxygenation layer, catchment layer and the dephosphorization layer.
The utility model adds a certain proportion of gac and plant ash formation novel ecological filler according to the composition of soil particle particle diameter in soil, the major ingredient of gac is a silicon-dioxide, stable in properties, can improve the porousness of soil, regulate the temperature of soil, keep the matter pine property of soil; The plant ash pH value is greater than 7, include K+, both can regulate the pH value of soil, increase soil alkalescence, guarantee carrying out smoothly of nitration reaction, can increase the organic matter of soil again, improve the physico-chemical property of soil, improve the sedimentation of soil, avoid the too fast sclerosis of hardening of soil, for microorganism provides good living space, guaranteed treatment effect.
