Sustain-released coagulant and device using same to process initial rainwater

Abstract

The invention discloses a sustain-released coagulant and a device using the same to process initial rainwater. The device comprises a device body and an agent storing groove, which is arranged on the middle interlayer of the device body. The lateral wall of the device body is made of a water-penetrating material layer. Hanging mechanisms are arranged over the two sides of the device body and used to hang the device body on the rainwater opening. The bottom of the device body is provided with a recessed groove for settling the sludge. The sustain-released coagulant comprises 10 parts of aluminum salt, 1 to 1.5 parts of absorbent, 2 to 3 parts of diatomite / clay, and 2.5 to 3.5 parts of paraffin fragments. The provided device can effectively collect the rainwater on the earth surface especially on the roads and process the rainwater to reduce the suspension concentration without affecting the normal discharge of rainwater. The initial rainwater can be processed by the device. The manufacturing is simple, the agents can be changed easily, and the processing effect is good. The provided device and coagulant have an important meaning for establishing a resource-conserving and environment-friendly society.

Description

technical field [0001] The invention relates to an initial rainwater treatment device, in particular to an initial rainwater treatment device for granulating and growing suspended matter particles in initial rainwater based on a slow-release coagulant and finally realizing solid-liquid separation. technical background [0002] Water is an important natural resource essential to human survival and an integral part of the entire earth's ecological cycle. Since the industrial revolution, with the continuous development of the economy and society, water resources have been continuously consumed, while the fresh water resources that human beings depend on are constantly being consumed, and at the same time, they are also facing increasingly serious pollution problems and the availability of fresh water resources is becoming scarcer. At the same time, the pollution produced by modern society not only pollutes the fresh water resources we depend on for life. [0003] In recent yea...

AI Technical Summary

Problems solved by technology

[0012] (1) The cost is high. Generally, only the electric valve and program control need about 150,000 yuan;

[0013] (2) Due to various reasons, this automatic control system is prone to failure. Once the valve fails, automatic rainwater switching becomes empty talk;

[0014] (3) It is difficult to operate. Due to the use of time control, there is a large difference in the amount of water between heavy rain and light rain, and there will be a lot of trouble when using it

[0019] Application number: CN201310693703.2, the name of the invention is a kind of urban rainwater collection irrigation system, this system also needs to add rainwater collection pipelines, storage tanks and other facilities on the existing roads, there are many parts that need to be transformed, and the cost is relatively high , not suitable for large area applications

And it does not have the ability to treat initial rainwater pollutants
