technical field

The utility model belongs to the technical field of rainwater collection and reuse, in particular to a water tank capable of adjusting the discharge flow of primary rain.

Background technique

Due to the increasing shortage of fresh water resources, the collection and utilization of rainwater resources have been paid more and more attention. In some cities and regions where fresh water resources are scarce, various systems are constantly being used to collect and utilize rainwater. Rainwater utilization is increasingly becoming an important measure to alleviate the urban water crisis and improve the urban water environment in the process of urbanization in my country. When rainwater is harvested and utilized, because the initial rainwater is polluted when it flows through the atmosphere, the surface of buildings, outdoor roads and the ground, there are more pollutants in this part of the rainwater, and the pollution degree is higher. Higher, collected together with later clean rainwater, the water quality treatment process is uneconomical. Therefore, in the process of collecting rainwater, it is very necessary to discard the initial rain runoff. Therefore, it is an important aspect of the utilization of rainwater resources to adopt an appropriate way to discard the initial rainwater.

Germany is the country with the best rainwater utilization in Europe. At present, the rainwater utilization technology has entered the stage of standardization and industrialization. The roof rainwater storage in Germany is to use simple treatment of rainwater to make it meet the water quality standard of miscellaneous water, which is used for urban greening , toilet flushing, garden watering, industrial cooling, etc. The United States restricts the direct discharge and loss of rainwater, controls the pollution of rainwater runoff, encourages the interception, storage, utilization or recharge of rainwater underground, and improves the urban water environment and ecological environment.

The utilization of urban roof rainwater is conducive to improving the ecological environment of the city and alleviating the increasingly serious water resource crisis. The water quality of roof rainwater runoff directly affects the use of rainwater, and the main pollutants of runoff are organic matter, nutrients and suspended solids. The main influencing factors of roof runoff pollution are: air pollution status, roofing materials, accumulation of atmospheric sediments on roofs during non-rainfall periods, rainfall, rainfall intensity, interval between two adjacent rainfalls, seasons, etc. The pollution of roof rainwater runoff is serious in the early stage, and it tends to decrease with the duration of rainfall. After the rainfall reaches 2-3mm, the water quality is better. In some cities, rainwater resources can be used to relieve water pressure. Therefore, the roof rainwater The development and research of sewage interception tanks and water tanks that can adjust the discharge of primary rainwater are of great significance. At present, my country has carried out research and application on this, and has achieved remarkable economic benefits, social benefits and ecological benefits, among which,
