A kind of inhibitor and its treatment method for controlling the peculiar smell of polluted soil

Abstract

The invention relates to an inhibitor for controlling the peculiar smell of polluted soil and a treatment method thereof. The raw materials of the inhibitor include component A, component B and component C, and the component A is an aqueous solution of polyaspartic acid or carboxylate Methylcellulose aqueous solution, the component B is an aqueous solution of sodium alginate, and the component C is an aqueous solution of calcium chloride or calcium nitrate. The method of using the inhibitor to control the odor of polluted soil is as follows: mix the component A and component B, spray it on the surface of the polluted soil, and then immediately spray the component C to quickly form a hydrogel on the soil surface film, so as to achieve the purpose of inhibiting the odor of polluted soil. The cost of the inhibitor for controlling the peculiar smell of polluted soil described in the present invention is low, the effective action time is greater than 7 days, and does not produce secondary pollution. The steps to control the odor of polluted soil can be realized.

Description

technical field [0001] The invention relates to the technical field of odor treatment and control in polluted sites, in particular to an inhibitor for controlling odor in polluted soil and a treatment method thereof. Background technique [0002] With the rapid development of industry and the acceleration of urbanization, the problem of site pollution is becoming more and more serious. Among them, site odor pollution is a typical nuisance pollution, and it is also the main complaint category of residents. It mainly acts on people's psychology through people's sense of smell, causing people to have Unpleasant feeling, and has certain harmfulness to human body. [0003] The sources of odor pollution are complex, the types and properties of the substances that produce odors are quite different, and the odor characteristics of different substances have different irritating degrees to the human body. In addition, the odor has the characteristics of short time and suddenness, so i...

Problems solved by technology

[0003] The sources of odor pollution are complex, the types and properties of the substances that produce odors are quite different, and the odor characteristics of different substances have different irritating degrees to the human body. In addition, the odor has the characteristics of short time and suddenness, so it brings great pressure to the environmental management department on the control of odor. Odor control is urgent; the control of odor pollution has always been a worldwide problem. The existing related technologies for odor suppression are high in cost, complicated in operation, short in effective time, and may even cause secondary pollution.
