A slow-release coagulant and a device using it for initial rainwater treatment

Abstract

The invention discloses a slow-release coagulant and a device for treating initial rainwater by using it, comprising a device body and a drug storage tank erected on a middle compartment of the device body, and the side wall of the device body is composed of a water-permeable material layer , The upper sides of the device body are provided with a suspension mechanism for hanging the device body on the rainwater outlet, and the bottom of the device body is provided with a groove for sludge deposition. The slow-release coagulant includes: 10 parts of aluminum salt; 1-1.5 parts of adsorbent; 2-3 parts of diatomaceous earth / clay; 2.5-3.5 parts of paraffin chips. The device can effectively collect the rainwater falling on the ground surface, especially on the road, and treat it without affecting its normal discharge, so as to reduce the concentration of suspended matter in the water. Treat initial rainwater. Its manufacture is simple, the replacement of medicines is convenient, and the treatment effect is good. It is of great significance in building a resource-saving and environment-friendly society today.

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
