The treatment system is simple in procedure and principle; and multiple treatment structures are connected in series, so that redundant matters in the sewage can be effectively and cleanly treated, the treatment effect is good, and the sewage can be up to the national water treatment standard.
Description
Technical field
The utility model relates to a kind of system, especially relates to the one way of life Sewage treatment systems, belongs to the field of Environment Protection that life is processed.
Background technology
Along with the continuous propelling with urbanization that develops rapidly of rural economy, the obvious improvement of life of farmers level and living condition, the domestic sewage in rural areas by using quantity discharged is also in continuous increase.Yet, owing to lacking of capital and environmental protection consciousness thin, domestic sewage in rural areas by using is substantially unprocessed just directly to be discharged, and peripheral natural water has been caused to severe contamination.In sanitary sewage, pollutent be take organism as main, also contain many microorganisms simultaneously, because being decomposed organic pollutant, therefore sanitary sewage is unsettled, biodegradable and perishable, directly be discharged in environment the pollution of removing to cause environment if not treated.Traditional sewage disposal technology developing history is longer, and treatment effect is better, but initial cost is large, and working cost is high, is difficult at the Rural areas spread.Because the pollutent in sanitary sewage is to take organism as main, its biochemical is better, so the generally processing of sanitary sewage is all the method that adopts biological treatment.From processing mode, divide: focus on and dispersion treatment.The method focused on adopts aerobe to process more, and reliable, treatment effect is good, but exist, initial cost is large, power consumption is many, working cost is high, excess sludge is processed the problems such as difficult; The decentralized approach great majority are anaerobic biological treatment, and treatment facility less investment, working cost are low, but quite a few treatment facility exists the problem that treatment effect is unstable, be difficult to reach emission standard.City domestic sewage is processed great majority and is adopted concentrated Wastewater Treated by Activated Sludge Process, but the incomplete suitable rural area of this method.
The utility model content
The purpose of this utility model be to overcome existing domestic sewage in rural areas by using quantity discharged little, disperse, intermittent large, processing rate is low, process inconvenient problem, designed the one way of life Sewage treatment systems, the flow process of this treatment system is simple, principle is easy, by the processing structure by multiple, be together in series, can be effectively that the unnecessary mass treatment in sewage is clean, processing effective, make sewage can reach national water treatment standard.
The purpose of this utility model is achieved through the following technical solutions: the one way of life Sewage treatment systems, comprise sewage collection system, described sewage collection system is connected with solid-liquid separation system, solid-liquid separation system is connected with equalizing tank, equalizing tank is connected with anaerobic digester system, anaerobic digester system is connected with artificial wet land system, and artificial wet land system is connected with outlet system.In the technical program, by a plurality of processing structures are connected together, utilize multiple processing mode, can be by the impurity in water body, organism, nutrient rich is processed clean, makes water body meet national emission request, the sewage after processing can be discharged into artificial aquarium fish canalization, water outlet flow into the villages and small towns pipe network system.
Be provided with some groups of grids in described equalizing tank, and the two ends of grid contact with the symmetrical wall of equalizing tank respectively.Grid is that steel rod intersects the obstruct hurdle formed anyhow, when equalizing tank is regulated in the potential of hydrogen of carrying out sewage, easily occur that sometimes precipitation or floss produce, after the grid of multilayer is set, throw out or floss can be intercepted, prevent from passage is stopped up.
Described artificial wet land system comprises sandy soils, be provided with the fine stone layer under sandy soils, be provided with thick metalling under the fine stone layer, and thick metalling contacts with the fine stone layer, sandy soils is connected with anaerobic digester system, and thick metalling is connected with outlet system; Rubble diameter in described fine stone layer is 15mm to 25mm; Rubble diameter in described fine stone layer is 20mm; The rubble diameter of described thick metalling is 35mm to 45mm; The rubble diameter of described thick metalling is 40mm.Rubble is that the sewage to seeing through sandy soils filters again, rubble is arranged to the level of different diameter, sewage can be carried out to filtration repeatedly, and the impurity in sewage is considered after clean and carried out draining.The diameter of metalling is selected according to concentration of wastewater and other situation.
Be provided with nonwoven layer between described fine stone layer and sandy soils, and nonwoven layer contacts simultaneously with sandy soils with the fine stone layer.Non-woven fabrics claims again tNonwovens, to be formed by orientation or random fiber, be environment-friendly materials of new generation, there are protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, cheap, the capable of circulation characteristics such as use again.Nonwoven layer is set in the utility model, and the water after sandy soils can being filtered appears, and can meet again the ventilative of sandy soils.
Described anaerobic digester system comprises anaerobic treatment pool, is provided with anaerobic bacterium in anaerobic treatment pool, and anaerobic treatment pool is connected with sandy soils.It rationally utilizes anaerobic digester system sewage disposal and its to organically combine, and has realized the resource utilization of sewage.Most of organism in sewage produces biogas after anaerobically fermenting, and the sewage after fermentation has been removed most of organism, reaches the purification purpose; The biogas produced can be used as bathroom and the home-use energy of cooking a meal; Sewage after anaerobically fermenting is processed can be used as watering water and views and admires water.Sanitary sewage purifying biogas generating pit or domestic sewage of villages and small towns purifying biogas generating pit are a kind of small-sized dispersion treatment devices, be applicable to the blowdown pipe network unsound, the economically underdeveloped area that there is no sewage centralized treatment plant, its Sewage treatment systems has decentralization in investment, oneself easily raise, can process nearby, working cost is low, do not need the personal management, adopt the underground reality of reserving for one's own use, the advantage such as do not take up an area, do not consume energy.
In sum, the beneficial effects of the utility model are: the flow process of this treatment system is simple, and principle is easy, by the processing structure by multiple, be together in series, can be effectively that the unnecessary mass treatment in sewage is clean, processing effective, make sewage can reach national water treatment standard.
