Description
Technical field
The present invention relates to the technical field for the treatment of tank, relate in particular to a kind of storage pond of tape handling function.
Background technology
Since reform and opening-up, Shanghai City government has dropped into huge fund, successively build up combined sewage and administered the engineerings such as first phase of construction, waste water control two, the third stage of the project, Suzhou River comprehensive improvement, by cutting the means such as dirty pollution treatment, make whole city's water surrounding looks have obvious improvement, basically eliminate is black smelly in central city river course at present, and central city point-source pollution has 85% to obtain damming.But quality of water environment is after the improvement obtaining to a certain extent, the difficulty improving strengthens, traces it to its cause, and be mainly that city early-stage rainwater pollution of area source is lacked to effective governing measure, cause early-stage rainwater also to become increasingly conspicuous to the contradiction of river course water environment pollution, it is very fragile that water surrounding maintains.
According to statistical information in recent years, in whole city's Main river, still have suitable river water quality unstable, especially rainy season, in time, has repeatedly, jeopardize the achievement of water environment treatment, be mainly reflected in three aspects, the one, because the interception ratio of combined system is low, the amount of damming is only equivalent to the rainfall amount of 1.25mm, cause rainy day overflow frequent, according to monitoring materials, the combined sewage pollutent COD concentration of rainy day overflow reaches 350mg/l, cause and approximately have the COD of 10,000 tons to enter river course, polluted-water every year; The 2nd, the dirty hybrid junction of rain of separate sewage system is serious, sewage enters river course by storm sewer, cause the pollution level aggravation of water body, according to relevant monitoring materials, the mean concns of separate system row river pollutent COD is between 50～300mg/l, every year approximately there is the COD of 20,000 tons to enter river course, polluted-water; The 3rd, conduit running water level is higher, is difficult to reach from clear stream speed cause alluvial during drought stream, and rainy season, settling rose again because flow velocity increases, and caused the dirty mixing water pollution load of overflow rain high, large to the impact of river course water surrounding.According to Shanghai City combined sewerage overflow pollution control countermeasure achievement in research, show, it is also one of main source of the rainy day pollution of river that pipeline settling rises.
The developed countries such as America and Europe, as far back as the seventies and eighties in last century, just the attention of water environment protection has been invested to the non-point pollution fields such as city rainfall runoff, Germany last century the seventies just start regulating and storing of combined sewer overflow to launch research, and widespread use, the U.S. also last century the seventies start rainwater runoff pollution and combined sewer overflow to pollute and administer, EPA (EPA) has proposed rainwater " optimal management method " (BMPs), target is from source, to start to control the runoff water yield and pollution load thereof, by reducing waterproof underlay area, increase infiltration facility, be detained, hold back equalizing tank, the measures such as wetland and perviousness paving, reduce the pollution of early-stage rainwater, alleviate heavy rain ponding, reduce the investment cost of system reconstruction.According to EPA (EPA) environmental statement in 2000, the domestic point-source pollution of the U.S. solves substantially, but river water quality still can not reach federal government or each state water quality standard, and tracing it to its cause is mainly pollution of area source.According to statistics, the U.S. still has the The Great Lakes area of 39% river, 46% lake, 51% river mouth and 78% still can not reach federal government or each state water quality standard.The improvement of polluting for early-stage rainwater, the U.S., also still in the starting stage, there is no the plan of putting things right once and for all, and difficulty of governance is very large and have a chronicity.
Domestic early-stage rainwater is administered at present also in the exploratory stage, owing to starting late, built and lag behind, to implementing to have increased many difficulties.Especially the ultra-large type city as Shanghai, superstructure stands in great numbers, underground utilities are intricate, Infrastructure land used is in short supply, draining system shunting with collaborate and deposit, water exhaust system builds up substantially, as planning control in addition as early as possible not, enforcement difficulty is from now on less by leeway larger, that adjust.Therefore, control early-stage rainwater (city surface source) pollution and become the Shanghai task of top priority of present stage, Shanghai takes the lead in carrying out the project study in early stage of early-stage rainwater improvement, the scope of improvement to more extensively, more deep future development, be conducive to improve the integral level of water environment treatment.
Therefore, those skilled in the art is devoted to develop a kind for the treatment of facility and pond type of can not only making and combines closely, also can realize irrigation channel distribution, reduce head loss, reduce energy consumption, be easy to management operating, effluent quality is good, produce mud few, save the area, the storage pond of the tape handling function of the feature such as operational management is more convenient.
