Abstract

The invention provides a toxic organic chemicals-contaminating soil emergency rapid device and a treatment method. A fixed amount of contaminated soil is added into a reaction tank via a feed hopper with the feeding amount accounts for 1/2 of the volume of the reaction tank, and water is added in accordance with a soil-water ratio of m:V=1:1 to uniformly mix the soil with the water under the rotary agitation of the reaction tank, pH of the soil in the reaction tank is regulated to be neutral; in the adding period of the treatment process, an oxidizing agent is added into the reaction tank to fully and uniformly mix the oxidizing agent with the contaminated soil under the rotary agitation of the reaction tank; then in the process of the reaction period, contaminants in the soil are fully reacted with the oxidizing agent under the rotary agitation of the reaction tank, and a heating mechanism is started when necessary; and in the final sludge discharge period, a rotation adjusting button on the reaction tank is turned off and the treated soil is discharged via a sample hole. The device and the method can be used for on-site rapid emergency treatment for the contaminated soil caused by leakage of toxic organic chemicals, diffusive contamination accidents, oil spillage accidents, etc.

Description

(1) Technical field [0001] The invention relates to a method for treating pollutants, in particular to a method for quickly treating polluted soil. The invention also relates to a device for rapidly treating polluted soil. (2) Background technology [0002] With the increasing use of chemical substances in industry, the industry is becoming more and more prosperous and developing, but it also brings huge risks. Sudden pollution accidents occur from time to time. Such accidents have various forms, occur suddenly, are difficult to deal with, The harm is serious, and it is one of the unstable factors that constitute society. The harm of sudden environmental pollution accidents to society has become one of the most concerned issues in the world today. Environmental pollution accidents are sudden in time, uncertain in form, serious in harm and difficult to deal with. If they are not handled in time, they will not only cause harm to the environment, but also bring harm to the pr...
