Accident waste water treatment and collection system

Abstract

An accident waste water treatment and collection system belongs to the technical field of waste water treatment devices and comprises a rain water pipe network and a municipal rain water pipe network connected therewith through a pipeline. A first control valve mechanism is arranged between the rain water pipe network and the municipal rain water pipe network in a matched manner; the rain water pipe network is connected with an accident emergency pool, a waste water treatment station, and a purified water collection pool sequentially; a second control valve mechanism is arranged between the rain water pipe network and the accident emergency pool; and the accident emergency pool comprises a collecting well, an oil isolation and sedimentation pool, and an accident collection pool. After adopting the above technology, the waste water receives emergency treatment before entering into a waste water treatment station, and explosive liquid is separated to prevent explosion and other hazards.The accident waste water can be completely collected, and after primary treatment, most water-insoluble hazardous chemicals are separated, so the whole system can realize linked control and high safety performance, and the accident emergency pool does not need to be buried deep, so the construction investment is reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment devices, and in particular relates to an accident sewage treatment and collection system for collecting and treating accident sewage produced by fire fighting and fire extinguishing after dangerous chemical accidents such as fire and explosion occur. Background technique [0002] Hazardous chemicals are prone to fire, explosion and other accidents in the process of production, use and storage. A large amount of fire-fighting water and foam are needed in the accident disposal, and these fire-fighting water and foam are mixed with dangerous chemicals, which generate a large amount of water in a short period of time. Accident sewage, causing secondary pollution to the environment. [0003] At present, although there are accident emergency pools in hazardous chemical production, use, and storage enterprises, because there is no complete and effective treatment method, the function of the acci...

Problems solved by technology

[0002] Hazardous chemicals are prone to fire, explosion and other accidents in the process of production, use and storage. A large amount of fire-fighting water and foam are needed in the accident disposal, and these fire-fighting water and foam are mixed with dangerous chemicals, which generate a large amount of water in a short period of time. Accident sewage, causing secondary pollution to the environment

[0003] At present, although there are accident emergency pools in hazardous chemical production, use, and storage enterprises, because there is no complete and effective treatment method, the function of the accident emergency pool is limited to collection, and there is no emergency treatment function. The capacity of the pool needs to be very large, and the floor area and investment also need to be very large.
