Problems solved by technology

Part of the sludge in the secondary settling tank flows back to the front of the aerobic tank, and part of it is discharged to the sludge tank; (4) The sludge generated in each stage can be transported to landfill or incineration after centralized sludge filtration and dehydration. The process provided by the invention still has room for improvement in the removal effect, especially the removal rate of dissolved organic matter and the removal rate of turbidity

Abstract

The invention discloses an alcohol wastewater treatment technology. The alcohol wastewater treatment technology comprises the following operation steps: (1) after removing relatively large impuritiesfrom alcohol wastewater through a grille, conveying the alcohol wastewater into an adjusting tank; (2) then lifting the alcohol wastewater through a pump into a primary sedimentation tank and carryingout pre-treatment; adding an alcohol wastewater treatment agent; (3) then conveying the wastewater into a hydrolytic acidification tank and a contact oxidization tank and carrying out biochemical treatment; conveying output water into a secondary sedimentation tank and carrying out mud-water separation, wherein the alcohol wastewater treatment agent is prepared from: Powdered carbon, ferric sulfate, ammonium chloride, aluminum chloride, hydrogen peroxide, a zeolite molecular sieve, iron powder, formic acid, polyacrylamide, sucrose acetate, tartaric acid and sodium caseinate. According to thealcohol wastewater treatment technology disclosed by the invention, the tartaric acid, the sodium caseinate and the sucrose acetate are used as a reinforcing system, so that a flocculation capabilityof the alcohol wastewater treatment technology is improved and the removing rate of dissolved matters of organic matters is improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an alcohol wastewater treatment process. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Since the composition of industrial wastewater is more complex, and some are toxic, industrial wastewater treatment is more difficult and more important than urban wastewater treatment. Alcohol wastewater is organic wastewater with high concentration, high temperature, and high suspended solids. The treatment technology started earlier and developed rapidly. The waste residue in the waste liquid contains crude fibers such as crushed cassava skin and rhizomes, which are insoluble COD in wastewater; cellulose and hemicellulose in cassava are polysaccharides, which cannot become yeast in alc...
