Abstract

Pond water of silver catfish (Pangasius sp) has high color value, turbidity, and organic compound with the color concentration 250 Pt-Co, turbidity 13.5 NTU, and organic concentration 197.56 mg/L. High concentration of color, turbidity, and organic compound in pond water of silver catfish caused the water should be treated. One of the treatment method is chemical treatment with coagulation-flocculation method. Pond water of silver catfish was treated into clean water using powder of Moringa seed (Moringa oleifera) as organic coagulant using coagulation-flocculation method with Jar-Test system. The aim of this research is to purify water with knowing the removal efficiency of color, turbidity, and organic compound by treating pond water of silver catfish using coagulation-flocculation method and determining optimum dose of coagulant. Jar-Test result showed the color removal efficiency as 86.00% in day 1; 90.75% in day 2; and 88.77% in day 3 with 60 ppm as optimum dose. Turbidity removal efficiency was 84,52% in day 1 and 87.80% in day 2 with 60 ppm as optimum dose. Organic compound removal efficiency was 73.87% in day 1; 77.13% in day 2, and 77.29% in day 3 with 60 ppm as optimum dose.

辣木对peasius SP塘废水的净化效果研究

银鲶鱼池塘水色值高，浊度高，有机物含量高，色浓度250 Pt-Co，浊度13.5 NTU，有机物含量197.56 mg/L。银鲶鱼池水颜色、浑浊、有机化合物浓度高，应进行水质处理。其中一种处理方法是混凝法化学处理。以辣木籽粉为有机混凝剂，采用混凝-絮凝法制备罐子试验系统，对鲢鱼池水进行净化处理。本研究的目的是通过混凝-絮凝法处理鲢鱼池塘水，确定混凝剂的最佳投加量，了解对水体的色度、浊度和有机物的去除率。Jar-Test结果显示，第1天的去色效率为86.00%;第2天90.75%;以60ppm为最佳剂量，第3天达到88.77%。在最佳投加量为60ppm的条件下，第1天和第2天的浊度去除率分别为84,52%和87.80%。第1 d有机物去除率为73.87%;以60ppm为最佳剂量，第2天77.13%，第3天77.29%。
