Description
Technical field
This utility model relates to a kind of Multi-level deflector formula Rain Garden system for processing early-stage rainwater.
Background technology
Along with the continuous quickening of Development of Urbanization, urban waterlogging, early-stage rainwater pollute and the black smelly problem in river course is increasingly severe, and these problems severely impact the life of resident with healthy.Being primarily due to High-speed Urbanization, city internal water system constantly reduces, and the coverage rate of waterproof pavement gradually rises, and causes oozing under rainfall runoff face impenetrably, causes serious urban waterlogging at urban inner after forming hydrops.Simultaneously because city surface source pollution problem is serious, rainfall runoff washes away the problem that road surface also can cause early-stage rainwater to pollute, and there are some researches show, pollutant levels in runoff: COD meansigma methods is 242mg/L, NH3-N meansigma methods be 323.5mg/L, TN meansigma methods be 419mg/L, TP meansigma methods be 10.9mg/L.Its pollution level is significantly larger than the elementary item standard V class water quality of water environment quality standard (GB3838-2002), belongs to bad V class water；If early-stage rainwater effectively not being purified and just entering natural water, it will natural water is brought severe contamination, thus aggravates the black smelly problem in river course.The pollution of urban waterlogging and natural water has become the subject matter of restriction Chinese Economy Development, take appropriate measures strengthen the retaining of rainwater, reuse, under ooze recharge of groundwater and to prevent natural water from polluting imperative.
