Abstract

The invention discloses an emergency disposal method for a water source polluted by arsenic trioxide. The emergency disposal method is safe and efficient and comprises the steps that a large amount of lime is added into polluted water to carry out neutralization and sedimentation; a dam is built on the upstream position of an accident point for closure, an artificial stream is excavated, the stream is changed to go around the accident point, polluted sand stone is mechanically shoveled, a large amount of cement and lime is poured into a bed bottom of the accident point to be stirred, and the polluted sand stone which cannot be cleared away in the bed bottom is solidified. The method can be widely applied to water quality protection, and guarantee is brought to drinking safety of downstream residents.

Description

A kind of for by the emergence treating method after arsenic trioxide polluted source
Technical field the present invention relates to the emergence treating method after a kind of pollution of waterhead, is specially a kind of for by the emergence treating method after arsenic trioxide polluted source.
Background technology arsenic trioxide also claims arsenic to have severe toxicity; the important industrial chemicals of industrial production and agriculture pharmacy, of many uses, along with the development of transportation; also the protection in seedbed of feeding water brings potential safety hazard, once its polluted source will the safe drinking water of serious threat downstream resident.
Summary of the invention the present invention is a kind of can solve the problem effectively for by the emergence treating method after arsenic trioxide polluted source, aims to provide one emergence treating method safely and efficiently.
Object of the present invention is achieved by following technical proposals; It is included in polluted water body and adds a large amount of limestone vegetation precipitations, build a dam in accident point upstream and dam, excavation artificial canal, current are changed its course and walks around accident point, with power shovel except contaminated sandy soil stone, a large amount of cement and lime to be poured at the bottom of accident point bed and to stir, the contaminated sandy soil stone cannot removed at the bottom of solidification process bed.
Below detailed description of the invention, the invention will be further described, after confirmation is by arsenic trioxide polluted source, takes rapidly above-mentioned measure, and detect downstream variation of water at any time, once change, notifies downstream water demand unit immediately.
The present invention can be applicable to the water quality protection of various water head site widely, brings guarantee to the safe drinking water of downstream resident.

Claims (1)
