waste water rate

Using FeCl 2, the protein recovery rate could reach over 80% and COD in waste water could be lowered by 77%.

使用它，蛋白质的回收率可达80%以上，且废水的COD可下降77%左右。

Using AC1 as catalyst, factors affecting COD decreasing rate in treating molasses alcohol waste water by internal electrolysis-catalytic oxidation process were studied, such as reaction time, waste water concentration, initial pH value, temperature.

在内电解&催化氧化法处理糖蜜酒精废液的研究中，以AC1作为催化剂，考察了反应时间、废液浓度、废液初始pH值、反应温度四因素对废液COD去除率的影响规律。

The output of materials increases at the rate of 11% every year, and waste water and waste gas make up the great part.

物质输出量以平均11%的比例逐年增长，废水和废气是其主要输出部分。
