Abstract

The invention discloses a recycling method of circulated cooling water of industrial wastewater with carbinol, which comprises the following steps: adopting hydrolytic adjusting pond; proceeding microbe contacting to oxidize; proceeding aerobic biological contact to oxidize; concreting; sedimenting; filtering through active charcoal; sterilizing through UV; adopting elastic cubic fill and microhole aerating system as fill of biological contact oxidizing course; decomposing organism with DO under 0.5-1. 0mg / l; removing CODcr, suspension and organism effectively.

Description

technical field [0001] The invention relates to the treatment and reuse of methanol industrial waste water, in particular to a method for treating methanol-containing waste water discharged from the production of methanol by a methanol plant and recycling it into circulating cooling water. Background technique [0002] Methanol is an important raw material in the production of pharmaceuticals, chemicals and pesticides. In the process of methanol production, the distillation raffinate discharged from the bottom of the rectification tower is usually called methanol wastewater. Methanol wastewater has a strong pungent odor, and its main components are methanol, ethanol, higher alcohols and aldehydes; it also contains some long-chain compounds. [0003] At present, the common methanol wastewater treatment methods include physical and chemical methods, chemical methods and biochemical methods, and these methods can treat methanol wastewater to varying degrees. Physicochemical a...
