Description

A kind of green building sub-district rainwater is collected the dirty system that cuts
Technical field
The utility model belongs to municipal engineering, environmental protection technical field, is specifically related to a kind of green building sub-district rainwater and collects the dirty system that cuts.
Background technology
Rainwater be municipal water circulation with the regional water circulating system in important step, to regulate, replenish regional water resource, improving the ecological environment plays a part very key.China is in the fast-developing stage of urbanization at present, and along with the raising and the rapid economy development of the urbanization level, the urban rainwater problem just more shows especially out.Mainly show as: rainfall runoff is seriously polluted; Flood risk in city strengthens; Rainwater resource runs off in a large number; Urban ecological environment destruction is serious etc.How the planning and designing of China's urban sewerage and drainage system directly discharges urban rainwater and to rely on simply on the traditional concepts such as " the dirty shuntings of rain " as soon as possible if much also only resting on, this can not satisfy the requirement of Modern Urban Development and ecological environmental protection.The urban rainwater problem is not only the key factor of the restriction national economic development, and is the serious social concern that threatens the people ' s health and the security of the lives and property.
The nineties in 20th century, U.S. heavy rain managerial expert has developed a kind of simulating nature hydrologic condition principle, based on the multiple spot microcosmic heavy rain control strategy of source control, i.e. and low influence exploitation (LID).LID pays attention to suiting measures to local conditions; Through a series of protectiveness designs; Measures such as biological delay, filtration and infiltration, clean runoff storage are carried out the ecology processing to rainfall runoff, and the natural hydrology before the recovery exploitation circulates as far as possible, accomplishes the control to the urban rainfall runoff water yield and water quality.Advantages such as in addition, the low more traditional rain flood of the development technique control technology that influences also has construction cost low, and operational management is simple.
At present, the LID technology is in the starting exploratory stage at home, does not form perfect theory and technology system as yet.The application that storm runoff is controlled at China also only limits to the some areas in city, and range of application is little, and the planning that advanced technology is supported has caused the effect of practical applications also not obvious with the design tool application level is lower or do not use.In the urban planning aspect, also not having special is the urban storm runoff management planning of purpose with flood control, water quality protection and view comprehensive effect, also seldom considers the Comprehensive Control to storm runoff in the master planning.
China's most city population density is big, lack of water, rainfall runoff are seriously polluted, and waterlogging takes place frequently, and ecological environment pressure is big, and therefore, exploitation has exigence based on the correlation technique of LID theory.In addition, domestic flourish sub-district exploitation and urban renewal also provide good opportunity and condition for the LID The Application of Technology.
Summary of the invention
The purpose of the utility model is based on the rainwater source region of low influence exploitation (LID) technology and urgees to ooze, cut dirty theory, provides a kind of green building sub-district rainwater to collect and cuts dirty system.During rainfall; The rainwater that collect City Green building sub-district inserts the water inlet of this system; Afterwards rainwater in this system by being accumulated, stored, permeate and adsorb, is filtered, finally reach to rainwater in the source region, urge to ooze, section dirt, the purpose of promptly the rainwater water yield and water quality being controlled.This system is applicable to can not provide large stretch of rainwater to concentrate the green building sub-district in the used greenery patches of Ecological Disposal; Each subsystem floor space is few, permeates exhaust system on the way with son between the subsystem and connects, and connects flexible relatively; Suit measures to local conditions, can confirm relative position between the subsystem according to actual conditions; Operating cost is low, and certain landscape effect is arranged.
The described a kind of green building of the utility model sub-district rainwater is collected and cut a dirty system, it is characterized in that: a plurality of subsystems by being located in the low gesture greenery patches are composed in series, and said subsystem cuts dirty osmosis system and son by son and permeates exhaust system on the way and form.
