Abstract

The invention relates to a method for preparing a basic green treating bio-adsorbent from baijiu vinasse and aims to solve technical problems of poor removal effects and proneness to secondary pollution in existing biological treatment. The technical scheme includes that the method for preparing the basic green treating bio-adsorbent from the baijiu vinasse includes steps: 1) steaming and boiling;2) ultrasonic assisted salting-out treatment; 3) alkali soaking; 4) hydrogen peroxide soaking; 5) ethyl alcohol soaking; 6) drying, to be more specific, drying filter residues in a constant-temperature blast drying oven at 60-80 DEG C to a constant weight; after drying, storing the filter residues in a sealed environment to keep for standby application. The method has advantages of waste recycling, no secondary pollution and great adsorption effects.

Description

technical field [0001] The invention relates to a method for preparing a biosorbent for treating alkaline green by using distiller's grains, which belongs to an environment-friendly production method of the original ecological green biosorbent. Background technique [0002] The printing and dyeing industry is a large discharge of industrial wastewater in my country, and its wastewater discharge is about 35% of the total industrial wastewater discharge. Dye wastewater has become an important source of pollution because of its complex composition, high concentration, deep color, and large discharge. Basic green is a kind of organic dye, which is weakly alkaline and widely used in the printing and dyeing industry. In addition, alkaline green has a very significant killing effect on fish parasites and molds in fish eggs, so it is also widely used in aquaculture. Basic green and its metabolites have been recognized as having potential carcinogenic, teratogenic, mutagenic and ot...
