According to the composting principle and the correlation between the forms of heavy metals and biological efficiency, combining with the controlling means of heavy metals' activity, this test studied the effect of passivation reagents including fly ash, phosphorate rock, zeolite, peat and lime on the forms and the biological efficiency of heavy metals; and the different perception of different passivation reagents were screened and optimized. Basing on the study, the adsorption mechanism of passivation reagents on heavy metals in sewage sludge composting was discussed, and the transformation mechanism of organic forms of heavy metals was also studied through some methods including dialysis and G-75 gel chromatogram separation etc.

The results of batch experiments showed that the anaerobic biodegradation kinetics of 2-CNB and 4-CNB by granular sludge were follwed by first-order reaction. The nitro groups of 2-CNB and 4-CNB were more easily attacked by electron than chlorines and they were reductively biotransformed to amino groups under anaerobic conditions. The acclimated anaerobic granular sludge, which could dechlorinate 4-chloroanline to aniline, showed that it had the ability of para-dechlorinating. The anaerobic biodegradating on pathway of 2-CNB and 4-CNB were suggested as follows:AbstractIn ZVI(zero-valent iron, Fe0)-reduction system, the nitro groups of 2-CNB and 4-CNB were reductively transformed to amino groups.
