Embodiment Construction

[0037] The present invention will be further described below through specific examples.

[0038] As shown in Figure 1(a) and Figure 1(b), the present invention is a device for automatically adding coagulant to the downpipe of a building to treat high-pollution runoff from the roof. High pollution load rain (snow) water runoff includes upper standpipe 3, lower standpipe 15, and the dosing cartridge 6 connected to the upper and lower standpipes obliquely, and is located above the dosing cartridge 6 and is connected to the upper standpipe 3 and the dosing pipe respectively. The evaporation tank body 25 connected to the dosing cylinder 6 is provided with a brake lock valve body 27 connected to the dosing cylinder body 6 below the evaporation tank body 25, and the brake lock valve body 27 passes through the connecting rod of the trapezoidal lock valve 20 The evaporation tank body 25 connected with 21 brakes the drug feeding cartridge 6 .

[0039] Among them, the cartridge 6 is arr...

Abstract

The invention relates to a device for automatic adding of a coagulant for treatment of roof high pollution runoff in a building downpipe. The device comprises a downpipe, an upper standpipe and a lower standpipe that are connected to the downpipe, a chemical dosing cylinder inclinedly communicated with the upper standpipe and the lower standpipe, and an evaporation tank that is disposed above the chemical dosing cylinder and is communicated with the upper standpipe and the chemical dosing cylinder respectively, and a brake lock valve body communicated with the chemical dosing cylinder is arranged below the evaporation tank. According to the invention, a rainwater collection pipe of an evaporation tank chamber and a chemical dosing cylinder water collecting chamber inclined plate are disposed in the standpipes, the evaporation tank is internally equipped with a piston, a connecting rod and a one-way braking system, wherein the one-way braking system depends on the cooperation of a spring leaf, a brake pin and a connecting hinge to complete chemical dosing control. The device provided by the invention can effectively treat overflow rainwater falling into the downpipe, and can completely rely on the falling water gravitational potential energy to complete initial rainwater water recognition and coagulant adding. The device has the characteristics of simple structure, convenient processing and manufacture, complete autonomic regulation, convenient replacement of coagulant and good treatment effect.

Description

technical field [0001] The invention relates to a device which utilizes the gravitational potential energy of precipitation runoff in a downpipe of a building to realize the identification of roof rainwater or runoff with high pollution load at the initial stage of snowmelt and the automatic addition of coagulant. Background technique [0002] Rainwater resource utilization can not only effectively reduce the harm of urban waterlogging, but also significantly alleviate the pressure of water shortage in urban development, which is one of the main contents of sponge city construction. Studies have shown that rainwater, as a water resource with relatively good water quality, can be used as urban miscellaneous water for road irrigation, greening and toilet flushing after preliminary treatment. However, the high pollution load of rainwater in the early stage of rainfall is one of the bottlenecks in the current use of rainwater. . Based on the characteristics of rainwater product...
