The invention relates to the technical field of sewage treatment, in particular to a sewage treatment method using biological activated carbon, which comprises the following steps: selecting corresponding strains according to the types and contents of main pollutants in sewage, and carrying out acclimatization and enlarged culture to obtain composite strains; selecting 4 mm columnar carbon as a filter material in a biochar filter tank, uniformly mixing the treated activated carbon with a composite strain, and culturing the strain to obtain biological activated carbon; then collecting black water and grey water generated on a ship through a drainage system, and carrying out primary filtration and flocculation treatment in advance to obtain pretreated sewage; finally, filling the obtained biological activated carbon into a biological carbon filter tank, then introducing the pretreated sewage into the biological carbon filter tank for adsorption treatment, discharging the treated discharge water into an ultrafiltration membrane assembly for ultrafiltration treatment, and then discharging the treated discharge water into an ultraviolet sterilization assembly for ultraviolet sterilization treatment; and after the detection is qualified, naturally discharging the water or feeding the water into a recycled water recycling system.

    本发明涉及污水处理技术领域,具体为一种利用生物活性炭的污水处理方法,包括以下操作步骤:根据污水中的主要污染物种类和含量选择对应的菌种,进行驯化和扩大培养得到复合菌种;选择4mm柱状炭作为生物炭滤池内的滤料,将处理后的活性炭与复合菌种混合均匀,培养得到生物活性炭;将船舶上产生的黑水及灰水通过排水系统进行收集,预先经过初级过滤和絮凝处理,得到预处理后的污水;将所得的生物活性炭填入生物炭滤池内,然后将预处理后的污水导入生物炭滤池内,进行吸附处理,处理后的排放水排入超滤膜组件内进行超滤处理,然后排入紫外线杀菌组件内进行紫外线杀菌处理,检测合格后自然排放或者进入回用水循环利用系统。
