A compact purifying tank to treat sewage in rural area of China: lab-scale and field-scale study

摘要

In China, the conditions of rural areas are quite different. The dispersed household and terrain difference allow the centralized system of sewage treatment being a challeng. Thus, it is urgent to set up the new mode of sewage treatment by buiding the highly efficient dispersed in-situ treatment engineering, which should be gauranted a long life time. Our group develop a novel purifying tank system based on the scientific research and enginnering experence, and propse the guidance of sewage treatment in rural area of China as well. Besdies the scientific work in the laboratory, several enginnering are carried out for various living modes in rural aerea. Specifically, the purifying tank combined with hydrolysis tank show a good performance in treating the sewage from single household, multi housholds, villa, apartment and small enterprise. The discharged water is prove to satisfy the discharging standard of Chinese goverment.
