Copper-ammonia complex wastewater treatment system and process

The invention provides a copper-ammonia complex wastewater treatment system and process. The system comprises an adjusting tank, a first reaction tank, a second reaction tank, a first sedimentation tank, an acid adjusting tank, a Fenton tank, an alkali adjusting tank, a second sedimentation tank, a neutralization tank, a third reaction tank, a third sedimentation tank, a fourth reaction tank, an A/O tank, a fourth sedimentation tank, a disinfection tank and a discharge tank which are sequentially arranged according to the wastewater treatment process. According to the wastewater treatment process provided by the invention, a chemical method, a biological method and a microbial method are combined, trimercaptotriazine trisodium salt is used as a heavy metal trapping agent, the wastewater issubjected to advanced oxidation by using a Fenton reagent, and nitrogen and copper in a water body are absorbed and removed by using chlorella vulgaris; eichhornia crassipes and pistia stratiotes areused for adsorbing ammoni
