Các chỉ tiêu ô nhiễm sau quá trình xử lý nước thải giảm đi khoảng : pH = 6.5, 86% độ đục, 81.3% SS, 60.4% COD, 51.7% BOD ta thấy hiệu quả chitosan tương đối cao.
The only goal the following pollution waste water treatment process reduced range: pH = 6.5, 86% opacity, 81.3% SS, 60.4% 51.7% COD, BOD, we see relatively high chitosan efficiency.
The pollution index after the wastewater treatment process reduced range: pH = 6.5, 86% turbidity, 81.3% SS, 60.4% COD, BOD 51.7% chitosan was found relatively high efficiency.
