| 化工行业一直是公认的工业污染大户。据统计， 化工污水 占我国工业污水的 21% ， 居第一位， 化工污水排放达标率仅有 52. 9% 采 仍是首选的方法。 Chemical industry has been recognized as a major industrial polluter. According to statistics, chemical wastewater accounts for 21% of China's industrial wastewater, ranking first, and only 52.9% of the discharge rate of chemical wastewater is still the preferred method. 但由于高含盐化工污水的可生化性能差， 用单一的好氧生物工艺处理难度较大。水解（ 酸化） 处理方法是 一种介于好氧和厌氧处理法之间的方法， 它广泛地应用于有机 污水的预处理。 However, due to the poor biodegradability of chemical wastewater with high salinity, it is difficult to treat it with a single aerobic biological process. Hydrolysis (acidification) is a method between aerobic and anaerobic treatment, which is widely used in the pretreatment of organic wastewater. |
