China is short of water resources, urban waterlogging is frequent in recent years, and rainwater utilization is gradually paid social attention. Urban rainwater is a natural resource, is very precious and should be collected and utilized. A building rainwater collection and utilization system is a general name of a system for collecting, distributing, purifying, storing and using rainfall accumulated on the roof of a building, the hardened ground surfaces of roads, squares and the like. The rainwater is used as a supplementary water source for greening, landscape water and cleaning water, and has positive significance for relieving urban inland inundation, controlling environmental pollution and improving groundwater level.
However, in the early stage of rainfall, a large amount of polluting gas and dust in the air are dissolved in the rainwater, the rainwater of the first 2-5mm is generally seriously polluted, and the rainwater can cause serious water pollution if the rainwater is directly used without being treated. At present, rainwater collection can be roughly divided into two types, namely roof rainwater and ground rainwater. Roof rainwater is relatively clean relative to ground rainwater, and impurity, silt and other debris are also few, can get into the retaining system after abandoning class and simply filtering. The ground rainwater has more sundries and complex pollutant sources, and before utilization, the rainwater must be disinfected after certain flow discarding, filtering and precipitation, so that the rainwater can be gathered into a water storage system. As mentioned previously, roof rain is better than ground, but is equally polluting. In the rainwater collection and utilization system, the flow discarding effect of the initial rainwater flow discarding device is directly related to the rainwater collection effect. If the initial rainwater discarding is not good, impurities in the sewage flow into equipment such as a rainwater treatment well and a water storage tank, the working strength of the filter is increased, the filter is blocked, the impurities accumulated for a long time are deposited and blocked at the bottom of the pool, the later-stage cleaning load is greatly increased, the maintenance cost is increased slightly, and the whole system is paralyzed seriously.
