Abstract

The invention relates to a preparation method of a low-carbon environment-friendly snow melting agent, and relates to the field of fermentative hydrogen production and snow melting agents. The snow melting agent is generated through an acid-base neutralization reaction at suitable temperature with commercial calcium carbonate and metabolic products (organic mixed acid) generated when fruit and vegetable waste is subjected to anaerobic fermentative hydrogen production at medium temperature (35-38 DEG C) or high temperature (53-55 DEG C). The product is low in price, convenient to use, free of toxicity and corrosion and biodegradable, has no adverse effect on the growth of plants and is the efficient low-carbon environment-friendly snow melting agent. In addition, a liquid component generated after the operation of a solid-liquid separation unit is a liquid product of the low-carbon environment-friendly snow melting agent; a solid component is a substance containing cellulose, hemicellulose and lignin of calcium phosphate and other mineral fertilizer, serves as a raw material of biochar production and is used for soil improvement.

Description

technical field

[0001] The invention belongs to the field of snow-melting agents, and relates to a method for producing snow-melting agents by utilizing the tails of hydrogen production by biological fermentation, in particular to a method for producing low-carbon and environment-friendly snow-melting agents by using the tails of hydrogen production by dark fermentation. Background technique

[0002] At present, there are two main types of deicing agents used in my country, non-chlorinated deicing agents and chlorinated deicing agents. The main component of non-chlorine deicing agent is potassium acetate. Chlorine deicing agent is divided into two types: chlorine salt type and mixed type. Chlorine salt deicing agent includes sodium chloride (salt), calcium chloride, magnesium chloride, chlorine Potassium etc. Mixed deicing agents are mixtures of chlorinated and non-chlorinated salts, some of which are added with rust and corrosion inhibitors.
