A kind of rainwater is collected and treatment system
Technical field
The utility model relates to water treatment field, particularly relates to a kind of rainwater and collects and treatment system.
Background technology
Water is human society one of the most important material conditions of depending on for existence, and China's water resources ownership per capita is about 1/4 of the world, and water scarcity has become the key factor of restriction China urban sustainable development.If can rationally utilize rainwater, abandon the rainwater commentaries on classics for receiving the back as living water uses such as green area irrigation, road surface flushing, Landscape River waters, improve the utilization rate of rainwater, limited resources are used crucial point to greatest extent.Common rainwater treatment device is general to adopt a rainwater collecting box to collect rainwater earlier; Collect Deng rainwater and to unify again to fully utilize after the filtration treatment after a certain amount of; But like this potential energy of rainwater has just wasted; Need to use electronic water treatment procedure, increased the cost of water treatment procedure virtually.
Water is the most valuable human resource, but because human waste and environment pollution cause clean water resources to reduce day by day.Along with society and rapid economic development, the city process is accelerated simultaneously, and water resource is exacerbated more, groundwater table decreasing; The water difficult problem in city also is on the rise, and in 600 cities of China 300 lacks of water is arranged, and having more than 100 of serious water shortage is individual, and just in rising trend; For this reason, country spends huge sums and carries out project of South-to-North water diversion, yet can only satisfy some areas problem of water consumption, can not fundamentally solve water shortage problem; Urbanization makes original vegetation and soil replaced by waterproof ground in addition, and a large amount of soil erosions have destroyed the natural, ecological hydrological environment, and underground water can not get effectively replenishing; Reduce year by year, urban ecological environment worsens year by year, and water content reduces in the soil, the heat island effect aggravation; Dryness of air, during rainfall, because the urban rainwater permeability is not strong, the rainwater aggravation compiles to the river course in city; Flood peak forms rapidly, and the load of urban sewerage and drainage facility is strengthened, and waterlogging disaster is taken place frequently, and rainwater is as a kind of water source of cleaning; If can obtain comprehensive utilization and control, will play positive role aspect environment and water resource utilization and the control, our human settlement, water conservancy ecology is also had profound significance.
A lot of in the world countries have had realized that the value of rainwater, begin to explore the Rainwater Resources utilization, adopt various technology, equipment and measure that rainwater is collected, utilizes, controlled and manages.In many resident families of Japan rain collector has been installed all, with rainwater water flowers, watering, carwash etc.Rainwater utilization is in China's stage in the early stage still, accepted by people and approves.Along with the wide-scale distribution of environmental protection concept and advocating of national energy-saving and emission-reduction, the collection of rainwater and recycle are in industry, agricultural with in living more and more widely.
Rainwater compiles common employing roof, ground level road, greenery patches, natural hillside etc., is being mingled with a large amount of pollutants, silt, impurity in the early-stage rainwater, and COD is up to 2000---3000mg/L; SS is up to 500--800mg/L, and colourity is nearly 100, therefore; Early-stage rainwater is answered the abandoned stream discharging; Collect clean rainwater of intermediary and later stages, simultaneously the contaminant filter of rainwater is got rid of, guarantee the normal operation of later stage water storage system; And guarantee draining safety, can reach the standard of industrial water use through the cleaning rainwater after processing and the evaporation filtration.
Traditional collection method has various combination ways such as early-stage rainwater stream abandoning device, catchpit, shunting well, early-stage rainwater filtration, grit chamber; Drawback is to have high input, and construction is complicated, and floor space is big; Management difficulty is high, is unfavorable for that rainwater resource utilizes extensive use.And for the discharge water of some industrial working rainwater, reclaimed water system, because of often containing a large amount of suspensions in the water, and the basicity of rain draining and hardness are all higher, and general civilian rainwater Collecting and dealing device is just inapplicable.
The utility model is to provide a kind of water that can be applicable to the discharge water of rain in factory area and reclaimed water system to collect and treating apparatus; And it is big to handle the water yield; Specified disposal ability is 500 tons/hour, rain draining after the processing and industrial water drainage industrial circulating water supplementing water, condensed water and the industrial water of being applied to capable of circulation.
The utility model content
The technical problem that the utility model mainly solves provides a kind of rainwater and collects and treatment system, can satisfy the water of rain in factory area and discharge water and collect and treating apparatus, and drop into lowly, and construction is simple, and operational administrative is convenient.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: provide a kind of rainwater to collect and treatment system; Comprise rainwater collecting pit, buffering regulating reservoir and clear water reserviors; Wherein cushion the regulating reservoir bottom and have the gradient, the buffering regulating reservoir is provided with the sand setting district, and clear water reserviors are provided with automatic tank level control system.
Preferably, in the said rainwater collecting pit diving mixer is set.
Preferably, said buffering regulating reservoir is pressed the flat flow design, and the pond bottom sloping is the 2-8 degree.
Preferably, bottom the said buffering regulating reservoir mud scraper is set.
Preferably, the water side of said buffering regulating reservoir is provided with the sand setting district.
Preferably, said sand setting district sidewall is provided with sludge pump.
Preferably, said clear water reserviors are provided with the overflow electrically operated valve.
Adopting the beneficial effect of the utility model technical scheme is in the rainwater collecting pit, diving mixer to be set, prevent solid impurity such as silt particle in the pond bottom sediments; The buffering regulating reservoir is pressed the flat flow design, guarantees certain gradient at the bottom of the pond, and mud scraper is set, and the water side is provided with the sand setting district, regularly body refuse is evacuated to sludge-tank through sludge pump; Clear water reserviors are provided with two electrically operated valves, and respectively by liquid level control, overfall is arranged on the delivery port top, when liquid level arrives overfall, starts the overflow electrically operated valve.This rainwater is collected with the treatment system floor space little, and applicable to containing plant area's rain draining, construction is simple, and it is convenient to manage.Produce water after treatment, the supplementing water or the factory industry water that can be used as recirculated cooling water use.
