Device for simulating and predicting water resource pollution in extreme rainfall weather and method thereof

Abstract

The invention discloses a device for simulating and predicting water resource pollution in extreme rainfall weather. The device comprises a water sucking pipe, a water pump, a water pressing pipe, at least one spraying head, a soil layer box, a collecting box, a water collecting trough for draining water in the soil layer box into the collecting box and a control box for starting or stopping the water pump in time and adjusting the lift and the flow of the water pump. The water sucking end of the water pump is connected with the water sucking pipe, the water outlet end of the water pump is connected with the spraying head through the water pressing pipe, the control box is connected with the water pump, the spraying head is arranged over the soil layer box, the collecting box is arranged on one side of the soil layer box, and the water collecting trough is arranged between the collecting box and the soil layer box; draining holes are formed in the lower end of the collecting box, and a plurality of water outlet faucets with different heights are arranged on the collecting box. The invention further discloses an implementing method of the device for simulating and predicting water resource pollution in extreme rainfall weather. The device is good in prediction effect, simple in structure and low in manufacturing cost, and the operating method is simple, practicable and easy to practice.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a device for simulating and predicting water source pollution under extreme precipitation weather and a method thereof. Background technique [0002] With the acceleration of urbanization in our country, the problem of water pollution has become increasingly prominent. Because of the advantages of excellent water quality and sufficient water volume, lakes and reservoirs and other types of water sources account for the proportion of domestic water sources such as lakes and reservoirs in urban water supply. Gradually rise. [0003] However, precipitation in most parts of my country is unevenly distributed in time and space, and extreme precipitation is not uncommon. On the one hand, thunderstorms, strong winds and strong convective weather often occur. These heavy precipitations will carry the surface sand, humus and other pollutants into the water source, causing serious ...

Problems solved by technology

[0004] The impact of this kind of extreme precipitation on the water quality of water source is not only during the occurrence of extreme precipitation weather, its impact time will last for several days or even more than a week, which seriously disrupts the normal operation of the waterworks, and it is difficult to ensure the long-term stability and comprehensiveness of the water quality of the waterworks. up to standard

Generally, there will be advance forecasts before the arrival of heavy precipitation. Before the arrival of extreme precipitation, the waterworks will have the opportunity to make full preparations to deal with it. The deterioration is serious. It often happens that the dosage of water treatment chemicals is not accurate, which makes it difficult for the effluent of the waterworks to reach the standard stably. It may even happen that the inappropriate selection of water treatment chemicals has no effect on water quality purification. After heavy rainfall occurs, due to lack of time or roads Blocked and can no longer call effective water treatment agents from other places
