Continuous pretreatment system and process for pirimiphos-methyl wastewater

The invention discloses a continuous pretreatment system and process for pirimiphos-methyl wastewater. The system comprises a wastewater storage tank, a first water pump, a heater, a three-dimensionalelectrocatalytic oxidation stripping tower, a first cooler, a neutralization kettle, a second water pump and a settling tank which are sequentially communicated, wherein the three-dimensional electrocatalytic oxidation stripping tower comprises a stripping tower and a three-dimensional electrocatalytic oxidation device arranged in the stripping tower. The process adopts the system to carry out continuous pretreatment on the pirimiphos-methyl wastewater. According to the system, the equipment cost can be reduced; meanwhile, the continuous treatment of the pirimiphos-methyl wastewater can be realized, energy is saved, labor intensity is reduced, and the system has the characteristics of remarkable treatment effect, low investment, low operation cost, convenience in engineering popularization and application and the
