Abstract:

Dsingikernsis chwright wastewater is highly concentrated organic wastewater. The alcohol is extracted fromthe first course water, and the second course water. The other wastewater is handled by biological treatment and physical and chemical technology. Anaerobic-aerobic technology is mainly used in biotechnology. UASB and anaerobic filters are adopted in anaerobic technology. Aerobic technology adopts contact oxidation. In physical and chemical technology, medical neutralization and deposition are used.

Key words: dsingikernsis chwright, wastewater, alcohol recycle, biological treatment
