Embodiment 1

[0047] (1) Preparation of inoculated sludge: Take 500ml of sludge and pour it into a fermentation bottle, heat it in a constant temperature water bath at 85°C for 30min. The sludge comes from the sludge dewatering room of municipal sewage treatment plants or industrial wastewater treatment plants (stations), with a water content of 80% and an organic matter content of 55% in the sludge. Under anaerobic and high temperature (55°C) conditions, the organic load (glucose concentration) was 5g / L, enriched and acclimated for 24h, or until gas production stopped.

[0048] (2) Preparation of the substrate: After washing fruit and vegetable wastes such as apples, bananas, and cabbage, beating is performed to obtain nutrients for fermentation and acid production. The solid content is 10.5%, the volatile components account for 94.3%, and the pH is 6.0.

[0049] (3) Preparation of low-carbon organic mixed acid crude product: Add 500ml of fruit and vegetable slurry to a 1000ml fermentation...

Embodiment 2

[0054] (1) Preparation of inoculated sludge: Take 500ml of sludge and pour it into a fermentation bottle, heat it in a constant temperature water bath at 90°C for 25 minutes. The sludge comes from the sludge dewatering room of municipal sewage treatment plants or industrial wastewater treatment plants (stations), with a water content of 85% and an organic matter content of 70% in the sludge. The organic load (glucose) is 10g / L, and the anaerobic enrichment and acclimatization at 35°C for 40h, or until the gas production stops, the obtained anaerobic activated sludge is the inoculum for the fermentation of fruit and vegetable waste to produce hydrogen.

[0055] (2) Preparation of the substrate: After washing fruit and vegetable wastes such as pineapples, oranges, yams, potatoes, etc., beating is carried out to obtain nutrients for fermentation and acid production. The solid content is 9.5%, the volatile components account for 95%, and the pH is 6.0.

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. [0003] Snow disasters will c...
