Abstract

The invention discloses a desalination method for synergistically treating edible mushroom saline water based on halophilic microbial compound bacterial agent and three-stage membrane technology. The method of the present invention is to add microbial composite bacterial agent I to edible fungus saline water, aerate and cultivate for 5 days; then desalinate the saline water through three-stage membrane treatment; Add microbial complex agent Ⅱ, aerated culture for 4 days. The method of the invention not only reduces the cost, but also the treatment method is more ecologically safe, and the desalination rate of the finally obtained edible fungi saline water can reach more than 97%.

Description

technical field [0001] The invention relates to the technical field of high-salt wastewater treatment, in particular to a desalination method based on a halophilic microbial compound bacterial agent and a three-stage membrane technology for cooperatively treating edible fungus saline water. Background technique [0002] Salting of edible fungi is a widely used way of processing and preserving edible fungi. Edible fungi can be processed into canned food or bagged convenience food that is convenient for storage and consumption. The amount of salt added in the salting process of edible fungi is as high as 20%-35%. Therefore, a large amount of high-salt wastewater is produced in the salting process of edible fungi and the subsequent desalination process, and its salt concentration is about 22%. The salt content is very high, its biodegradability is poor, it is difficult to handle, and direct discharge produces serious environmental pollution problems. Traditional desalination m...
