Method for automatically treating high-concentration toxic organics in soil or water

Abstract

The invention provides a method for automatically treating high-concentration toxic organics in soil or water, which comprises the following steps that: (1) a certain number of pollutants to be treated are added into a reactor, wherein the quantity of the pollutants accounts for 1 / 4-1 / 2 of the effective volume of the reactor, the reactor is rotated, a potassium ferrate oxidant is continuously added into the reactor, the pH value of the system is adjusted to 7.0-9.0 by 2 percent of sulfuric acid, the reactor degrades the pollutants under rotating and mixing, and the content of the pollutants is detected; and (2) after an oxidizing reaction is completed, a product is neutralized by 2 percent of sulfuric acid. The method for treating soil and water point sources polluted by toxic organics can achieve a good removing effect in a short time so as to effectively degrade toxic pollutants and eliminate toxicity harms in time, and secondary pollution is reduced to the maximum extent. The method can be used for fast treating soil / water point source pollution caused by sudden pollution accidents due to the leakage of toxic organic chemicals.

Description

technical field [0001] The invention relates to a method for treating pollutants, in particular to a method for removing toxic organic substances in soil or water through chemical oxidation. Background technique [0002] With the development of the economy, the types and quantities of organic chemicals continue to increase. During the production, storage, transportation and use of organic chemicals, leakage accidents sometimes occur, resulting in point source pollution of soil and water environment. Some organic chemicals, such as pesticides and phenol, are toxic organic substances that are extremely harmful to the environment and human health. Such pollutants must be dealt with quickly, otherwise secondary pollution accidents may be caused, and the scope and degree of harm may be expanded. [0003] At present, the treatment methods for point source pollution of toxic organic substances in soil / water mainly include: physical method, biological method, chemical method, etc. ...
