The indigenous microorganisms existed in the contaminated soil could degrade low concentration of chlorophenol 00mgg^(-1, however, their degradative capacity was limited when chlorophenol concentration was high about 500mgg^(-1, which may be caused by the toxic effect of high concentration of chlorophenol on the indigenous bacteria.

土壤中存在的土著的氯酚降解菌可以对低含量的氯酚100mgg^(-1进行降解；但是当土壤中氯酚含量较高500mgg^(-1时，土著微生物的降解能力受到限制，这可能是高浓度的氯酚对土著的氯酚降解菌会产生毒性作用。

And the culturable bacterial degraders were increased from 10^6CFUg^(-1) soil to 10^8CFUg^(-1) soil after inoculating with the degrader. Moreover, the bacterial population increased faster in 100mgg^(-1) microcosoms than in 500mgg^(-1) microcosoms, revealing that the inoculated bacteria could survive and enhance the biodegradation of chlorophenol in cuntaminated soil.

接种外来微生物后，土壤中可以培养的氯酚降解菌的总数从开始的10^6CFUg^(-1)增加到10^8CFUg^(-1)，并且，在氯酚含量为100mgg^(-1)的土壤样品中，微生物数目的增加比在氯酚含量为500mgg^(-1)土壤样品中更快。

In the detection experiments, the scan rate is set at 0.3 V/s under the analysis of linear sweep voltammetry. On the cyclic voltammetry plot, each pair of clear redox peaks was observed for 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), and penta- chlorophenol. The potentials of the redox pairs were 1.218 and -0.460 V for 4-CP, 1.128 and -0.448 V for 2,4-DCP, and 1.037 and -0.473 V for PCP.

在侦测污染物的实验之中，使用0.3 V/s做为线性扫描伏安法的最佳扫描速度，利用循环伏安法扫描可测得4-氯酚、2，4-二氯酚及五氯酚水溶液中氧化与还原波峰，4-氯酚的氧化与还原电位为1.218与-0.460 V、2，4-二氯酚之氧化与还原电位为1.128与-0.448 V及五氯酚之氧化还原电位为1.037与-

Ozonation could not reduce TOC completely, the results of HPLC and GC-MS showed that p -CNB was mainly transformed into p -chlorophenol, p -nitrophenol, 2-chloro-5-nitrophenol, etc ., and carboxylic acids with low molecular weight.

HPLC和GC-MS结果表明，ClNBs主要被转化为氯酚、硝基酚、氯代硝基酚、硝基苯、氯苯和低分子的羧酸等物质。

More and more attention is focusing on the safty of drinking water suply. In this paper, firstly, chloramine formation and the characteristics and kinetics of monochloramine autodecomposition were studied. Secondly, considering the high concentration of ammonia and the complication of organic matters in Shanghai Huangpu River, formation characteristics and rules of disinfection byproducts were reviewed during the breakpoint chlorination process, and on the basis of grading and clssification of organisms, the control effects of chloramination on DBPs formation were studied. Finally, the formation rules of 2-monochlorophenol, 2,4-dichlorophenol and 2,4,6-trichlorophenol from phenol chlorination were investigated, and related influencing factors and kinetics were analysed.
