Description
Technical field
The utility model relates to rainwater processing technology field, relates in particular to a kind of buried rainwater biological aerated filter system.
Background technology
Rainwater is the important step in nature water circulation system, to regulating, supplement the ecological ring of regional water resource and improvement and protectionBorder plays a part very crucial. Because China's problem of environmental pollution is particularly thorny, air pollution is serious, causes the rainfall initial stage,Rainwater has dissolved the pollution gas such as airborne a large amount of sour gas, vehicle exhaust, behind rainwater landing ground, again owing to washing awayAsphalt felt roofing, asphalt concrete road, construction site etc., make to contain in early-stage rainwater a large amount of organic matters, pathogen,The polluters such as heavy metal, grease, suspended solid, pollution level is very high, impact load is large, therefore should make purified treatment.
The domestic collection and use engineering for early-stage rainwater is at home also in the elementary step at present, and particularly arrange in existing cityWater system also cannot effectively filter contaminative early-stage rainwater, Collection and use; This not only cannot bring into play rainwater to regulate,The effect that supplements regional water resource and improvement and preserve the ecological environment, and along with the circulation of contaminative rainwater, cause widerPollution, be therefore necessary to design a kind of buried early-stage rainwater filtration system.
Utility model content
The utility model object is exactly in order to address the above problem, and has proposed a kind of buried rainwater biological aerated filter system, pinCannot effectively process contaminative early-stage rainwater to existing drainage system, use Modern mechanical design theory and theory, be intended to design onePlant buried rainwater biological aerated filter system, thereby effectively process contaminative early-stage rainwater.
To achieve these goals, the utility model adopts following technical scheme:
A kind of buried rainwater biological aerated filter system, comprises casing; The two ends of described casing are respectively water inlet and delivery port;In described casing, be provided with at least 2 and filter double-edged fine-toothed comb; Described filtration double-edged fine-toothed comb divides box house to be divided into successively sand setting district, filtrationDistrict and catchment; The top of described sand setting district and filtering area is designed with access hole; In described filtering area, be added with biofilter material; InstituteState filtering area bottom aeration tube is installed; Described aeration tube is connected with air blast.
Described casing is cement or steel or plastic preform; Described casing is installed in the drainage system in city.
Described water inlet is sand setting district to the region of filtering between double-edged fine-toothed comb;
Described sand setting is provided with flexible hanging ladder in district, and the hanging ladder that will stretch in the time that staff overhauls puts down, and overhauls with clearDeposit in reason sand setting district; After having overhauled, the hanging ladder that will stretch is packed up.
On described access hole, protective cover is installed, prevents that pedestrian from falling in casing accidentally, ensure pedestrian's safety.
Described filtration double-edged fine-toothed comb effectively filters the particulate pollutant in early-stage rainwater.
Region between described filtration double-edged fine-toothed comb is filtering area.
Preferred described biofilter material is made up of stalk-coal ash fiber haydite; Flyash and stalk collocation are used ammonia nitrogen, phosphorusAbsorption property better effects if; The source of described stalk is abundant, and cheap, it is required that the stalk after use contains plant growthThe nutrients such as nitrogen, phosphorus, potassium and calcium, therefore the fiber haydite after absorption can also use by as fertilizer sources.
Described aeration tube one end is connected with air blast, and the other end is connected with oxygen outlet.
On described aeration tube, check valve is installed, prevents that the rainwater in filtering area from flowing out from aeration tube.
Described aeration tube is that many perforated pipes are layed in bottom, biofiltration district, for the aerobic microbiological on biofilter material provides oxygen.
The beneficial effects of the utility model are:
The utility model is a kind of buried rainwater biological aerated filter system, by filtering double-edged fine-toothed comb, casing is divided into sand setting district, mistakeFilter district and catchment, can realize the notch cuttype processing to early-stage rainwater; By design hanging ladder, access hole in sand setting district, sideJust staff clears up maintenance to sand setting district; By be designed with biofilter material and aeration tube in filtering area, effectively remove rainPollutant in water, thus the treatment effect to rainwater improved.
