造纸废水处理中厌氧颗粒污泥钙化的案例分析

An analysis on a case of calcification of anaerobic granular sludge in the treatment of papermaking waste water

通过对某废纸制浆造纸企业废水处理中内循环厌氧反应器中颗粒污泥钙化的案例分析,发现厌氧颗粒污泥快速钙化的直接原因是厌氧塔进水Ca^2+浓度持续偏高。给出了降低厌氧颗粒污泥钙化速度的一些具体措施,可供有类似问题的废纸制浆造纸企业参考。

After analyzing of the case of granular sludge calcification in an internal circulation anaerobic sludge reactor in the wastewater treatment for a paper enterprise producing with waste paper,it can be found that the constantly high Ca^2concentration is the direct reason of the anaerobic granular sludge calcification.Some concrete measures to reduce the rate of calcification of anaerobic granular sludge were given in this paper,which could be used as the reference for paper enterprises with such problems.
