Study On The Utilition Of Industrial Area's Collected Rainwater

With fast development of chinese ecomomy and large scale construction of industrialization,large amounts of hardened ground appeared, so the osmosis of rainwater was reduced,and the appearance time of flood peak ahead, the increase of quantity of flood peak, the polluted water,water sources shortage,ground subsidence and so on. As a kind of cheap and clear water sources,if the rainwater were collected and used,it has become a promising subject.This subject not only has some economic benefit,but also has greatly environmental and social benefit.Based on a lot of abroad and domestic references, the actuality of rainwarter usage overseas and interiorly are introduced, significance of rainwarter usage in industrial area was discussed, general step in design of rainwarter usage engineering in industrial area was discussed:first, to assemble all the relevant industrial area's information was carried out, and industrial area's condition was analyzed, based on practical condition rainwarter pollution is predicated by model or is monitored on-the-spot; then it's need to analyse quality and quantity requirement of rainwater which is reused by industrial area, then the collecting and using system's scale of rainwarter was cimformed to divide industrial area into several rainwarter collection sections; it's necessary to reconstruct a variety of underline surfaces,and then a suitable technology treatment was selected to meet the requirements of the reuse rainwater quality and quantity; what's more the modularization process design for technology equipment and technology treatment was discussed,reuse rainwarter engineering's administration and monitoring method was conformed; after presenting several plans, through comprehensive evaluation, the best scheme was choose.This paper gives an example of rainwater treatment engineering design by using technology and equipment of reusing rainwater. In the end, the research results and deficiency was summarized, the further Development of the industrial area's reusing rainwarter was given.
