Coffee processing wastewater is one of the major agro-processing wastes that put high pollution pressure in coffee growing and exporting countries affecting water, soil, and human health. The processing industries apply no or low efficient technologies for management due to a lack of economic and technological feasibility. The purpose of this review was to assess ever practiced and studied management options of coffee processing wastewater and design feasible alternatives suitable for coffee-producing and agrarian regions. Treatment/management efficiencies of the advanced oxidation process, coagulation-flocculation, adsorption, wetland system, anaerobic digestion and fertigation along with their limitations were considered in this review. Most importantly, this work demonstrates fertigation as the first choice of coffee effluent management for agrarian coffee-producing countries due to low cost, additional nutrient value and ease of technological application.

咖啡加工废水是主要的农业加工废料之一，对咖啡种植国和出口国造成了巨大的污染压力，影响了水，土壤和人类健康。由于缺乏经济和技术可行性，加工业没有采用或采用低效率的技术进行管理。这篇评论的目的是评估咖啡加工废水的实践和研究管理方案，并设计出适用于咖啡生产和农业地区的可行替代方案。在这篇综述中考虑了先进氧化工艺，混凝-絮凝，吸附，湿地系统，厌氧消化和施肥的处理/管理效率及其局限性。最重要的是，
