摘　　要：有机磷农药废水COD值高、毒性大、可生化性差、组分复杂,排放前必须进行有效处理。综述了处理机磷农药废水的生化法及其吸附、水解、混凝沉淀等预处理方法,常规化学氧化法、超临界水氧化、电化学氧化、光催化降解法等化学法、物理法和超声波法等处理方法。展望了今后有机磷农药废水降解研究的主要方向,包括新方法、新设备的开发、去除机理及影响因素、动力学模型、新微生物菌种、先进检测技术等。为有机磷农药废水处理工艺的选择和设计提供指导和依据。Organic phosphorous pesticide wastewater is characteristic of high value of COD, strong toxicity, poor biodegradability, complicated constituents. Therefore, effective treatment of the wastewater is required before discharge. The biochemical treatment including pretreatment processes of adsorption, hydrolysis and coagulation sedimentation process, the chemical treatment processes such as conventional chemical oxidation, supercritical water oxidation, electrochemical oxidation, and photoeatalytic oxidation, the physical treatment processes and ultrasonic methods for treatment of organic phosphorous pesticide wastewater were reviewed in this paper. The prospects including the development of new methods and apparatus, removal mechanisms and key factors, dynamic models, microbial strains selection, and advanced detection techniques were also discussed and summarized. This review is helpful and valuable for selecting and designing processes for treatment of organie phosphorous pesticide wastewater.
