Description
Technical field
The utility model relates to a kind of Sewage treatment systems, relates in particular to a kind of earthworm artificial swamp ecological filter.
Background technology
Along with the fast development of China's economy and the growth of population, quantity of wastewater effluent also constantly increases, particularly China's domestic sewage in rural areas by using uncontrollable discharge is one of important factor causing pollution of water and eutrophication, the important and difficult task of of administering of Ye Shi China water pollution.In addition,, along with the development of China's plant husbandry and aquaculture, it is more and more important and urgent that effective processing of agricultural crop straw and breeding waste seems.According to statistics, China produces more than 700,000,000 ton of agricultural crop straw every year, but only there is 30% left and right to be used as the prepared using of paper industry, construction industry and handicraft, remaining more than 500,000,000 tons of stalk is burned or is discarded, not only cause waste, and burn in a large number contaminate environment, soil mineralization, even brings other social loss; Simultaneously, China's livestock and poultry cultivation development in recent years rapidly, particularly develop especially rapidly take milk cow, laying hen, pork pig as main aquaculture, and modern farming is high-density breeding, clustered raising degree is high, breeding pollution thing quantity discharged is large, and a large amount of wastes that produce because of cultivation have caused great pressure to the ecotope of China, the trend of stretching in even oriented city, if do not paid attention to, and solved, will seriously be hindered the developing steps of China's livestock industry.
Constructed wetland waste water treatment technology provides a kind of feasible way for solving China's domestic sewage in rural areas by using.But artificial swamp always produces mud in use procedure, especially, in inlet channel, mud gathers, as cleaning not in time, by the effect that impact is intake and whole wetland is disposed of sewage; Mud itself also needs through harmless treatment.In addition, the function of artificial swamp is comparatively single.
Earthworm is a kind of omnivore, and their organic substances of eating, are decomposed and transformed by the biochemical action in mechanical mill and the enteron aisle of gizzard, excretes with the form of wormcast, forms in soil that business is abundant, colory crumb structure.Research shows, earthworm can significantly increase nitrogen, phosphorus, the potassium available nutrient content in soil, and can improve urase in soil, sucrase and microorganism active, strengthens soil supplying nutrient capability.Therefore, utilize the microorganism synergy in earthworm special biological function and environment, can transfer to the bio-organic fertilizer for comprehensive nutrition such as mud, agricultural crop straw, breeding waste, realize innoxious, the minimizing processing of all kinds of wastes.Therefore, earthworm and ecological filter becomes one of effective way addressing the above problem.
Utility model content
The utility model, for the above-mentioned technical problem existing in artificial marsh sewage treatment system in prior art, provides a kind of earthworm artificial swamp ecological filter, in effectively disposing of sewage, the mud producing is carried out to biological degradation; And can carry out ecology processing to the waste of other agriculturals and aquaculture.
For this reason, the utility model adopts following technical scheme:
Earthworm artificial swamp ecological filter, comprise successively inlet channel, pretreatment pool, constructed wetland bed, discharge channel, between described inlet channel and pretreatment pool, be connected by the first siphon pipe, pretreatment pool is contiguous and higher than constructed wetland bed, some water distributors are layed in the top of constructed wetland bed, water distributor is opened on the bottom of pretreatment pool, on water distributor, offer some water vents, water distributor outsourcing has nonwoven layer, it is characterized in that: the end at described discharge channel is also disposed with earthworm filter tank and fermentation vat, between discharge channel and earthworm filter tank, be connected by the second siphon pipe, earthworm filter tank comprises humic soil layer from top to bottom successively, the first filter screen and gravel bed, in described fermentation vat, be provided with stirring rake.By the combination in constructed wetland bed and earthworm filter tank, comprehensive treating process domestic sewage in rural areas by using, mud and breeding waste, agricultural crop straw etc., can meet the multiple needs of countryside wastes processing, simultaneously, turn waste into wealth, one of important sources providing fertilizer is provided.
Further, described the first filter screen is configured to be inclined upwardly from discharge channel to fermentation vat, and the side in earthworm filter tank near fermentation vat is provided with earthworm separate tank.The first filter screen being obliquely installed can form a water level gradient, the in the situation that, water level more at sewage being higher, offers the place that selection of earthworm is fled from; In the time that sewage exceeds normal ranges, earthworm separate tank can form the place of earthworm escape, in addition, and the vegetable mould after also can separating earthworm and carry out a biological disposal upon for manual intervention.
Further, the bottom of described inlet channel is the inclined-plane tilting to pretreatment pool, is provided with the second filter screen in the bottom of inlet channel.The second filter screen is for filtering the solid matter of sanitary sewage; The bottom that inlet channel tilts utilizes the dry and pre-treatment of mud.
Further, described constructed wetland bed comprises the first gravel bed, aerobic layer of sand, the second gravel bed from top to bottom successively, on the first gravel bed, plants and is implanted with wetland plant.Can make the abundant microbial film adhering to matrix, stromal surface of sewage and the root system of wetland plant contact, strengthen matrix, microorganism and the wetland plant absorption removal effect to pollutent.
Further, described the first siphon pipe and the second siphon pipe are respectively one and fall " U " shape pipe, respectively have water-in, top and water outlet.Realize automatic drainage; And preliminary blowdown.
Therefore, the utlity model has comprehensive treatment capability strong, the advantages such as low maintenance cost, in addition, it is simple in structure, also low to the requirement of topographic structure, is adapted at rural area and promotes the use of.
