Description
Technical field
The invention belongs to the dirty water decontamination handles technical field, be specifically related to a kind of gravity abandoned stream defecator.
Background technology
Rainwater has become the primary pollution source of urban water pollution, and the pollutant of water environment are mainly brought by rainwater.This pollution is referred to as non-point pollution (pollution of area source), is more difficult to prevention and control for relatively conventional point-source pollution.Developed country just had started to explore " green building " or the development strategy of " Sustainable Building " and technology in the sixties in 20th century.Britain BREEAM, i.e. English architecture academy environmental assessment method, it mainly includes water saving (rainwater reuse), Water-quality control (runoff pollution) and water rate control (runoff, flood) content.China gradually payes attention to rainwater management and utilization, sets up modern city rain flood Comprehensive Control and utilizes system extremely the most urgent.
The important lakes such as China Taihu Lake, Dian Chi, non-point pollution has become the one of the main reasons of water quality deterioration, and rainwater runoff pollution the most gradually causes the attention of people.Meanwhile, China's storm sewer design capacity is the most backward, and pipeline amasss silt for a long time and causes pipeline obstruction, and rainwater is not directly discharged into pipeline through prime pretreatment, blocks pipeline so that impeded drainage, cause Urban Flood Waterlogging, meanwhile, contained harmful substance severe contamination subsoil water.At present, market is badly in need of this type of sewage disposal device, it is possible to collection floating thing, silt separate with rainwater, and dmp filter, rainwater collection is integrated in one, thus reduces generation and the rainwater pollution impact on water environment of Urban Flood Waterlogging.But, there is unreasonable structure in this kind equipment of the prior art, filter efficiency is low, and filtering medium layer is difficult to the problems such as cleaning.
Summary of the invention
The present invention is to solve above-mentioned technical problem, provide a kind of gravity abandoned stream defecator, solve the problem of pipe blockage that in rainwater, floating thing and silt cause, and the silt after precipitating can be discharged in time, dirt is taken out without power, meanwhile, collecting, before storing, the harmful substance in rainwater has been done filtration and adsorption treatment, defecator reasonably designs while solving pipeline obstruction, dmp filter collection problem, improve filter efficiency, and having energy-conservation, the life-span is long, feature easy to use.For achieving the above object, present invention employs techniques below scheme: a kind of gravity abandoned stream defecator, including the water inlet arranged on device cavity and its, outlet, overfall, sheathed inner barrel in described device cavity, described inner barrel lower half is furnished with through hole, inner barrel bottom is installed in the bottom of device intracavity, annular housing is formed between device cavity and inner barrel, described annular housing middle section position is filled with filtering medium layer, the rain sewage via through holes flowing into precipitation intracavity flows into annular housing, and through drain pipe discharge after filtering by filtering medium layer；The bottom of described device cavity is additionally provided with and is connected externally to the abandoned stream pipe led to.
Described device cavity and inner barrel are concentric circular tube structure, and the water inlet pipe that described water inlet is provided with extends through cylinder sidewall and bottom cylinder, and described overfall is higher than outlet.
The time relay that the electrically operated valve that described abandoned stream pipe is provided with is provided with device containment portion by cable is connected, and described precipitation intracavity is provided with in the circuit of float switch, float switch relay turn-on time and electrically operated valve.
Being provided with backwashing pump, Backwash pipeline and back flushing nozzle in described device cavity, described back flushing nozzle is evenly arranged in the top of filtering medium layer, and the spout of back flushing nozzle is straight down.
The outside of described device cavity is additionally provided with collecting pit, the drain pipe that described water outlet is provided with, and is connected with collecting pit by filter chamber.
It is provided with well lid at the top well head of described device cavity.
Described filter medium is sand or activated carbon, and particle diameter is at 0.5-10 millimeter.
Compared with prior art, the method have the advantages that
(1) present invention collects floating thing, silt separates discharge, and rainwater harmful substance Filtration Adsorption and rainwater collection are integrated in one, and solves pipeline obstruction, dmp filter collection problem, decreases the harmful substance impact on water environment in sewage；
(2) present invention is in use for some time, and the silt being deposited in bottom of device can be discharged in time by the flushing of the follow-up rainwater of water inlet pipe, it is not necessary to power takes out dirt, efficient energy-saving；Meanwhile, the electrically operated valve that is provided with by described abandoned stream pipe, the time relay, the cooperation of float switch so that abandoned stream and blowdown more convenient to operate；
(3) the rain sewage via through holes flowing into precipitation intracavity in the present invention flows into annular housing, and logical filtering medium layer filter after discharge through drain pipe, before collecting storage, the harmful substance in rainwater is done filtration and adsorption treatment, decrease harmful substance and enter runoff, alleviate the pressure of environmental pollution, wherein annular housing coordinates with the through hole of laying, increases filter area, improves filter efficiency；
(4) back purge system that the present invention is provided with at filtering medium layer, cleans filtering medium layer periodic reverse, decreases the foreign material being blocked in filter medium, improve the service life of device.
