摘要:

水产养殖尾水中悬浮颗粒物含量是重要的水质参数,悬浮颗粒物的去除对水产养殖和减少尾水排放污染具有重要意义。悬浮颗粒物的主要来源是残饵、鱼类粪便和微生物等,悬浮颗粒物的粒径、比重和沉降速度是重要指标,针对不同的悬浮颗粒物的特性,本文介绍了目前常用的处理技术,主要包括沉淀、筛网过滤、介质过滤、泡沫分离、臭氧氧化、电絮凝和生物过滤等,并对今后的水产养殖中悬浮颗粒物的控制和处理技术革新进行了展望,为水产养殖业内人士提供参考和借鉴。

Abstract:

The content of suspended solids in aquaculture effluent is a critical water quality parameter. Their removal is significant for aquaculture operations and reducing pollution from wastewater discharge. The primary sources of these suspended solids include uneaten feed, fish feces, and microorganisms. Key characteristics such as particle size, density, and settling velocity serve as important indicators for treatment design. In response to the varying properties of suspended solids, this paper reviews current treatment technologies, including: sedimentation, screen filtration, media filtration, foam separation, ozonation, electrocoagulation, and biofiltration. Future prospects for innovation in controlling and treating suspended solids in aquaculture are discussed, providing reference and insights for industry professionals.

Key words: aquaculture, water treatment technology, suspended solids, screen filtration, foam separation
