Abstract

The invention relates to processing equipment and a processing method for methyldopa sewage. The equipment comprises a regulating tank, a Fenton oxidation reaction tank, a primary sedimentation tank, a hydrolysis acidification tank, an anoxia tank, an aerobic tank, and a secondary tank, wherein, the regulating tank, the Fenton oxidation reaction tank, the primary sedimentation tank, the hydrolysis acidification tank, the anoxia tank, the aerobic tank, and the secondary tank are connected in sequence and form integrated processing equipment. The processing equipment and the processing method for methyldopa sewage combine the advantages of advanced oxidation and biological processing together. Ammonia and nitrogen of methyldopa sewage processed by the processing equipment can be effectively degraded, and chroma and COD are decreased. Therefore the methyldopa sewage is processed to meet the demand of discharging into a pipe net. The processing equipment and the processing method for methyldopa sewage have the advantages of low processing cost, simple operation and easiness in control.

Description

technical field [0001] The invention relates to waste water treatment equipment and a treatment method thereof, in particular to a methyldopa waste water treatment equipment and a treatment method thereof, and belongs to the technical field of pharmaceutical waste water treatment. Background technique [0002] Methyldopa is a receptor-blocking cardiovascular drug, which has been identified as a national Class B basic medical insurance drug for the treatment of hypertension and has a good market prospect. Methyldopa production wastewater mainly comes from the process mother liquor and washing wastewater in the production process. The water quality and quantity fluctuate greatly, the water quality is complex, there are many types of organic matter, and it contains high concentrations of dichloroethane, methyl chloropropyl ester, ammonia, and alcohol. , methyldopa and other pollutants, COD Cr It is as high as tens of thousands of mg / L, but B / C is low, even lower than 0.2, the ...
