Description
Technical field
The present invention relates to sanitary sewage disposal technical fields, and in particular to a kind of processing method of country sewage.
Background technology
Gradually urbanization is said in life in the countryside, and sanitary sewage is essentially from the lavatory flushing water, kitchen water, washing machine of farmers'
Draining, shower drainage and other drainings, for country sewage since area disperses, the size of population is larger, collects the reasons such as difficulty and causes agriculture
Village's sewage becomes the main compositing factor of water pollution, also has the inorganic salts such as a large amount of organic matter and nitrogen, phosphorus in country sewage,
Odorant is also easy to produce under the action of anaerobic bacteria, wastewater treatment in China industry development is later, with the rapid development of the national economy,
People's living standard significantly improves, sewage disposal increase in demand, and the water pollution caused by China's country sewage discharges is suitable
Seriously, paid much attention to by environmental protection administration；
Treatment method for rural sewage mainly has High-Rate Algae Pond, oxidation pond, contact oxidation method etc. at present, High-Rate Algae Pond compared with
Traditional stabilization pond residence time is short, and floor space is small, and it is easy to build, and easy maintenance, capital expenditure is few, and operating cost is low；Ammonia
Nitrogen and pathogen removal efficiency are high, but it is easily by such environmental effects such as temperature and ph；Oxidation pond removal efficiency is low, easily leads
Ecological disruption is caused to become black and odorous water, catalytic oxidation treatment effect is preferable, but sewage disposal capital cost and sewage disposal operating charges
With larger, it is therefore desirable to find a kind of method of suitable rural sewage treatment, make rural sewage treatment effect stability, operating cost
It is relatively low, and pass through rational sewage water treatment method and country sewage is maximized into comprehensive utilization.
Invention content
The purpose of the invention is to overcome the problems of the prior art, a kind of processing method of country sewage is provided.
The present invention provides a kind of processing methods of country sewage, include the following steps：S1, country sewage is introduced into grid
Well cleans, and the water outlet of grille well enters primary sedimentation basin, and pulverized limestone is put into primary sedimentation basin, carries out preliminary sedimentation,
The water outlet of primary sedimentation basin enters aeration tank, and aeration tank water outlet enters secondary sedimentation tank；The sludge reflux of secondary sedimentation tank extremely exposes
Secondary sedimentation tank remaining sludge after the sludge concentration in aeration tank reaches demand, is introduced eco-filtration bed by gas pond；
The water outlet of S2, secondary sedimentation tank enter artificial swamp, and artificial swamp includes planting soil layer from top to bottom, soil and
Vinegar grain compound layer, gravel layer and Flyash Layer, planting plants on artificial swamp；
The water outlet of S3, artificial swamp enter eco-filtration pond, and eco-filtration pond includes inlet channel, ecological filter bed and draining
Pipeline, it is ecological filter bed to be followed successively by the soil horizon for earthworm movement, wooden slag layer, cobblestone and biological ceramic particle from top to bottom, it is described into
Waterpipe is located between soil horizon and wooden slag layer, and drainage pipeline is located at the lower section of biological ceramic particle；
Remaining sludge is transported to eco-filtration in S4, the house refuse that step S1 grille wells are filtered out and step S2
Pond by dealing with earthworm house refuse and sludge, obtains the fertilizer for being suitble to crop growth, and eco-filtration pond drainage pipeline goes out
Water is used for crop irrigation.
Preferably, in soil and vinegar grain compound layer, the weight ratio of soil and vinegar grain is 30~45：1~8.
Preferably, the processing time of primary sedimentation basin is 8~12h.
Preferably, the pH value of artificial wetland effluent is 5~9.
Preferably, the grain size of cobblestone is 4~7cm, biological ceramic particle grain size is 2~4cm.
Preferably, drainage pipeline road includes helix tube, permeable cloth and antiseepage cloth, the permeable helix tube periphery that is laid in
Upper surface, antiseepage cloth are wrapped in the outer surface of helix tube bottom.
Preferably, planting plants are one or more of Semen Coicis, reed, cattail, hybrid giant napier and Scirpus tabernaemontani on artificial swamp.
Compared with prior art, the beneficial effects of the invention are as follows：The processing method of the country sewage of the present invention, using activity
The mode that sludge, artificial swamp method and earthworm and ecological filtering ponds method are combined carries out multistage purification processing, earthworm to country sewage
The gastral grinding of earthworm and metabolism cause the organic matter in rubbish and sludge in sewage disposal gradually to degrade, and release
Can be by nitrogen, phosphorus, potassium that plant utilizes etc., the nutty structure earthworm excrement of discharge is a kind of biological organic fertilizer of high-quality, can be used
In rural area crop growth fertilizer, there is fertility foot relative to chemical fertilizer, pollute the characteristics of small；Inlet channel is located at soil
Between layer and wooden slag layer, the high-hydroscopicity of wooden slag layer is that the breeding activity of earthworm improves enough humidity, at the same through cobblestone and
Biological ceramic particle carries out adsorption filtration again so that purified water quality is more preferably stablized, and drainage pipeline uses helix tube, gas permeability
Well, flow velocity is fast, and permeable cloth is filtered water outlet, and wooden slag or rubble is avoided to enter drainage pipeline, the antiseepage of drainage pipeline bottom
Cloth can prevent the infiltration of moisture from being lost in, and improve water yield, for the irrigation water of rural area crops, increase the utilization of sewage
Rate, water-saving fertilizer-saving turn waste into wealth, and are suitble to be widely popularized in rural area.
