摘要

为了评价新型环保液压支架液压液的生物降解性能,以含5%浓缩液的液压液为试验原水,采用一套基于水解酸化+A/O工艺的中试处理装置,测试该中试装置对原水的CODGr降解效果,判定该液压液的生物降解可行性。结果表明:在反应器水温为24～27℃,水解酸化、反硝化、硝化工艺段的停留时间分别为20、20、100 h的条件下,采用水解酸化+A/O工艺处理新型环保液压支架液压液,可将原水的CODGr从6 000～8 000 mg/L降低到300 mg/L以下,最低低于150 mg/L,CODGr总平均去除率达到96.7%,由此可知,该液压液是生物可降解的。提高硝化池的溶解氧浓度有利于降低出水CODGr。该液压液具有环境友好的特点,在液压支架中推广使用对矿区井下水环境影响很小。
Abstract

A set of pilot device was estabilished for assessment of biodegradation feasibility of new environmental friendly hydraulic liquid(5% concentrate in water) by treatment of hydrolysis acidification+A/O process. The feasibility of biodegradation of liquid was determined by removal effect of CODGr.The results showed that tem perature of water in the pilot device was at 24 ~ 27°C, and the retention time of the hydroacidification,denitrification,and nitrification stages were 20,20,and 100 h,respe ctively,under these conditions,the CODGr of the raw water has been reduced from 6 000 ~ 8000 mg/L to less than 300 mg/L,with the minimum of less than 150 mg/L an d the total average removal rate of CODGreached 96.7%. The higher concentration of dissolved oxygen in the nitration tank could increase the removal of CODGr.The b iodegradation of the hydraulic fluid was feasible.Therefore,the hydraulic liquid had the characteristics of environmental friendliness and its application in hydraulic supp ort had lttle effect on mine well environment.
