Abstract

The invention discloses a methyl ester wastewater treatment device in saccharin production, and relates to the technical field of wastewater treatment equipment. Comprising an adjusting cylinder, a coagulation cylinder, a biological reaction cylinder, two particle separators and a plurality of groups of delivery pumps. Waste water enters the adjusting cylinder after being subjected to primary impurity removal through the particle separator I, and the PH of the waste water is adjusted through cooperation of the circulating stirring structure and the acid-base property adjusting mechanism; the wastewater is subjected to secondary impurity removal through a second particle separator and then enters a coagulation cylinder to be mixed with a flocculation agent to generate flocculate, and a turbidity detection sensor is matched with a liquid extraction branch pipe to screen qualified wastewater; qualified wastewater enters the biological reaction cylinder, deep degradation is realized through the MBR and the aeration system, and a floating ball drives a shaking frame and a vibrating inner plate to prevent membrane blockage; after flocculate is separated by the treatment box, wastewater is recycled and reused; the device is compact in structure and high in automation degree, can efficiently remove wastewater impurities and refractory pollutants, ensures that wastewater reaches the standard and is discharged, and meets the large-scale wastewater treatment requirement of saccharin production.
