On the other hand, with the rapid development of science and technology, the mass rise of buildings and impervious roads gradually separates water from people's control, the problem of waterlogging continuously occurs in cities, and the property and life safety of people are seriously influenced.
The sponge city can solve the problems well, and aims to enable people to reasonably regulate and control rainwater so as not to be out of control, such as green buildings, permeable road pavement, rainwater gardens and the like. The rainwater is regulated and reasonably utilized, the utilization rate of rainwater in the first-line cities such as the wide north and the wide north in China can reach 10%, the utilization rate of rainwater in other cities, particularly villages and towns is almost zero, and compared with 20% or even 50% in developed countries, a harmonious mode of water symbiosis needs to be actively searched.
Compare in surface runoff rainwater, roofing runoff rainwater is cleaner, changes in the utilization ratio of the rainwater that improves. When rainfall falls on a roof, rainwater washes air and the roof, a large amount of dust and pollutants are mixed in water, and if the rainwater is directly discharged into natural water, serious pollution is caused, so that initial rainwater must be subjected to flow discarding treatment. The initial abandon flow is mainly influenced by rainfall scouring strength and rainfall interval, which also causes the change range of water quality to be larger, is difficult to determine the uniform abandon flow, and has important influence on the collection of roof rainwater. Meanwhile, the quality of the rainwater which is abandoned to flow through reaches the use standard, the rainwater is fully collected and reasonably utilized, and the problem of water resources can be effectively relieved.
Chinese patent application CN206245378U discloses a roof rainwater collecting, storing and recycling system, which comprises a roof rainwater collecting pipe network, a filtering system, a water using end and an electromagnetic valve control system. This patent technique can carry out stage filter with the rainwater to store respectively in different storage tanks, but the different water environment requirements of adaptation. The following problems still remain: 1) the initial rainwater discarding of the roof is not considered, and the subsequent treatment operation and cost of the rainwater runoff can be increased when the pollution concentration is high; 2) the system is complex in collection, carries out decentralized processing on rainwater, is low in efficiency and high in cost, and initial roof rainwater runoff which does not reach the standard is conveyed to a sewage pipe network, so that rainwater is prevented from being processed dispersedly independently, the efficiency is high, and water resource pollution is reduced.
Chinese patent application CN113152586A discloses a roof rainwater automatic collection system based on-line water quality monitoring, which comprises a water quality on-line monitoring device, a signal transmission and control device and a rainwater collection device. This patent can realize that initial stage rainwater abandons a class according to quality of water to roofing runoff quality of water on-line monitoring: however, two problems still exist: 1) the water sample measuring chamber of the system can influence the monitoring of the sensor due to the existence of initial-stage flow-discarding rainwater, so that the monitoring is deviated, the occupied area and the cost are increased, the system can be directly connected with a rainwater vertical pipe, and the precision of online water quality monitoring is improved by arranging a water quality monitoring pipe with a small pipe diameter and a rainwater branch pipe; 2) the water quality monitor is not accurate enough only by a turbidity meter, when the turbidity of rainwater in the measuring chamber floats, the electromagnetic valve can be repeatedly opened and closed, and the loss is large.
