NOVELTY - Biochemical process method of acrylic ester industrial wastewater involves adding water and alkali to wastewater; transferring wastewater into primary anaerobic tank (3); adding EMO microorganism strain with anaerobic function and active carbon carrier; processing hydrolysis, acidification and methanation biological reactions; transferring into primary aerobic tank; adding EMO microorganism strain; processing aeration operation; and removing organic pollutants and transferring sewage into primary water collecting tank to be buffered.    USE - Method for biochemically processing acrylic ester industrial wastewater.    ADVANTAGE - The method utilizes special sieved and tamed efficient biological microorganism strain to process acrylic ester wastewater. The strain can be degraded completely and there is no secondary pollution. In the flocculation step, the clean water processed purified process system reflows to the pre-treating system to be used for the second time. The method can save a large amount of fuel and steam compared with the combustion wastewater process method, thus providing obvious economic benefit.
