Description
Technical field
The utility model relates to a kind of rainwater-collecting recycling system, and particularly a kind of zero energy consumption roof rain water reclaims Waste water utilization system.
Background technology
China is a water scarcity, and flood, waterlogging, drought evil be country frequently.The population of China accounts for 22% of world population, and the fresh water occupancy volume is only 8%, and per capita water resources quantity is only 2500m
3/ year, be about world occupancy volume per person's 1/4, be equivalent to 1/6 of the U.S., Canadian 1/58, occupy the 110th, the world, be listed in one of 13 poor-water states in the world.China's water resources shortage not only simultaneously, and spatial and temporal distributions is uneven, the lack of water city mainly is distributed in North China, northwest, northern Shandong and coastal area, and the imbalance between supply and demand of the north and coastal area is more outstanding.
In China, urban water shortage mainly contains three basic forms of it: Engineering-type lack of water, contamination type lack of water, resource-type lack of water.The Engineering-type lack of water refers to cause city the pressure of water to occur lacking because of the deficiency of water intaking, water supply project, facility.The contamination type lack of water refers to lose the urban water resource deficiency that value causes because urban water resource is contaminated, and the water supply gets situation that occurs.The resource-type lack of water refers to that existing water resources quantity is not enough to support the water requirement in city and the water supply, the short water supply situation that occur.In reality, for a city, often there is the water shortage problem of two three types to exist simultaneously.
By contrast, what the most easily solve is the Engineering-type lack of water,, as long as strengthen fund input, increases and builds water intaking, water facilities, just can obtain the effect of getting instant result.The contamination type lack of water solves more complicated.The improvement of surface water pollution is relatively easy, and the time used is also relatively shorter.The improvement of groundwater pollution is very difficult, and needs long time, needs supreme a century decades when serious.Process not only technical sophistication of contamination type water shortage problem, large and related non-fund, the technical factor of fund input is also a lot, therefore comparatively complicated.For the resource-type lack of water, the one, should make great efforts to seek new water source, the 2nd, on the basis of city water resource research evaluation result, scientific and reasonable formulation urban planning and developing goal, so that the water demand in city does not exceed the ability to bear of city water resource.
The Chinese city rainwater utilization is started late, and some small-sized, local nonstandard parasexuality application are mainly arranged in water-deficient area at present.The situation is tense due to lack of water, and the work paces of Beijing are very fast.Calendar year 2001 State Council approved comprise " the early 21st century capital water sustainable use planning " of making use of rain and flood planning content.Beijing Inst. of Civil Engineering ﹠ Arch and Beijing city water saving office are studied since project verification in 1998, and April calendar year 2001, are tested and appraised, and start to apply with demonstration project in city; Beijing municipal administration designing institute starts project verification establishment design for rainwater utilization guide; Beijing Municipal Government's 66 commands also explicitly call for the rainwater utilization engineering of carrying out urban district in (on December 1st, 2000).
Originally, the Application of Urban Rain Water of China is only to have some small-sized rainwater harvestings to utilize engineering in some water-deficient areas.The ground such as the jade tablet island in Changdao County, Dalian in Shandong and Zhoushan Huludao City, Zhejiang Province are more typically arranged.Along with increasing substantially of China's production in recent years, domestic consumption, the contradiction of water resource anxiety, various places excessive exploitation underground water, cause groundwater table to descend, Groundwater Resources Depletion, the utilization of urban rainwater resources just causes relevant expert scholar's attention all the more, and the utilization that also in succession conducts a research of many metropolis such as Beijing, Shanghai, Dalian, Harbin, Xi'an, demonstrate good growth momentum.
