Abstract

The invention discloses a desalination method for cooperatively treating edible fungus salinizing water based on halophilic microorganism complex inoculants and a three-stage type membrane technology. The method comprises the following steps: adding a microorganism complex inoculant I into the edible fungus salinizing water, and aerating and culturing for 5 days; then, carrying out three-stage type membrane treatment on the salinizing water to realize desalting; and finally, adding a microorganism complex inoculant II into the salinizing water subjected to three-stage type membrane treatment, and aerating and culturing for 4 days. The method disclosed by the invention has the advantages that the cost is reduced, the treatment method is more ecological and safer; a desalination rate of the finally obtained edible fungus salinizing water can be over 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...
