Description
Technical field
The present invention relates to the cleaning treatment system of a kind of waste water, sewage, rainwater, the tandem rainwater ecological particularly relating to a kind of organic waste water and rainwater treatment field that are applied to city domestic sewage, foodstuffs industry and agricultural filters and clean catch device.
Background technology
At present, urban surface rainfall runoff carries a large amount of earth's surfaces pollution substance and enters collection storm-water system, due to Urban Rainwater Runoff Pollution thing conveying there is discontinuity and burst, its pollution load can raise in a short time at double, can on city converge receive impacting property of water body impact.
Natural rainfall water quality is generally better, principal pollutant are wherein suspended solid (SS), generally substantially can be purified by the method (precipitation, filtration) of physics, but when rainwater, (rainwater falls and the surface contacted with city underlying surface, as roof, walkway, driveway etc.) contact time, by the contaminants on underlying, water degradation can be caused; Secondly, because in rainwater, BOD and COD content ratio is lower, biodegradability is poor, adopts general biochemistry pool technology to be not suitable for; Moreover, for the occasion such as driveway, motor pool, the greasy dirt in rainwater and heavy metal content higher, pollutant removal difficulty, the cost of process is higher, limits the reuse of rainwater.
The technique means of existing rain collector many employings initial Split-flow, namely the 2-5mm rainwater of initial rainfall is discharged by the dirty pipe of draining that low level is uncovered by initial Split-flow device, then closes draining dirt pipe, collects rainwater afterwards, purify.But, initial Split-flow has larger randomness and uncontrollability: on the one hand, if rainfall underlying pollutant load is more, 2-5mm precipitation cannot be washed away totally, the rainwater then collected subsequently still containing more pollutent, so not only can strengthen the strainer working strength of rain collector, cause filter stoppage, and impurity leaves standstill at the bottom of rear sedimentation basin long-time, cleaning work directly to the later stage brings very large trouble, even causes whole rain collector to be paralysed; On the other hand, be that rainfall appears in the place that greenery patches or pedestrian's pavement etc. comparatively clean in city underlying surface, initial rainfall water quality pollutant content is less, and initial Split-flow has wasted the initial rainfall of 2-5mm, wastes water resources.
Existing rain collector is more employing physical filtering device also, namely adopt specific surface area large, active large porous filter-material carries out adsorb to pollution substance contained in rainwater and fixes, porous filter-material is as zeolite, haydite, coral sand etc., above-mentioned filtrate has stronger filtration capacity really to rainwater within a certain period of time, but along with filtrate hole, contaminated thing blocking or filtrate upper surface are blocked by the material such as rubbish, fallen leaves gradually, its filtration efficiency also continues to reduce, and causes the rainwater quality collected to be guaranteed.
Because above-mentioned defect, the design people, actively in addition research and innovation, to found a kind of novel texture rainwater treatment, collection device with adaption demand, have more using value.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one to avoid initial Split-flow, carry out ecological purification, improve research advances and large particulate matter can be avoided to block physics filter, the tandem rainwater ecological increased the service life filters and clean catch device.
