Problems solved by technology

[0006] However, a zinc catalyst is added to this deodorant, which increases the production cost of the deodorant virtually. At the same time, after a large amount of zinc enters the soil along with the flushing solution, the soil enzymes will lose their activity. , the number of bacteria is reduced, and the function of microorganisms in the soil is weakened, which eventually affects the normal growth of vegetation and is not conducive to the protection of the environment

Abstract

The invention relates to an environmental-friendly high-efficacy deodorant. The environmental-friendly high-efficacy deodorant comprises the following components in parts by weight: 7 parts of itaconic acid copolymer, 3 parts of ethylene diamine tetraacetic acid, 3.5 parts of sodium carbonate, 1.5 parts of sodium fatty alcohol polyoxyethylene ether sulfate, 1.6 parts of sodium dodecyl benzene sulfonate, 3.7 parts of glycol, 1.5 parts of corrosion inhibitor, 2.6 parts of edible essence, 2.6 parts of polyquaternary salt and 73 parts of distilled water. The environmental-friendly high-efficacy deodorantnot only can remove hydrogen sulfide and ammonia nitrogen, but also can remove common malignant odors such as thiol and amine in the petroleum industry, does not contain heavy metal ions such as manganese and chromium, chlorine ions, phosphorus and other toxic and harmful components, is highly biodegradable, does not produce toxic and harmful gas in a construction process such that personal injuries and environmental pollution are avoided, and does not jeopardize equipment, can effectively prevent ferrous sulfide from being spontaneous combusted and can remove hydrogen sulfide.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an environment-friendly high-efficiency deodorant and a preparation method thereof. Background technique [0002] In the process of petrochemical and crude oil processing, harmful odorous substances such as hydrogen sulfide and ammonia nitrogen are commonly found in hydrogenation units, hydrocracking units, catalytic units, coking units, and sewage stripping units. These malodorous substances are mainly transformed from sulfur-containing compounds and nitrogen-containing compounds in crude oil. In particular, hydrogen sulfide is a harmful substance that can paralyze human nerves and even cause death instantly. It is a substance strictly regulated by the environmental protection management department. Ammonia gas in the gas and ammonia nitrogen in the liquid are also important harmful substances, and the sewage needs to be strictly treated before being discharged. Ammonia in the at...
