Research status and trend of rural integrated domestic sewage treatment equipment
Since the beginning of the 21st century,rural domestic sewage treatment has undergone a development period of 20 years.Following the initial stages of anaerobic methane,land percolation,and constructed wetland ecological treatment,research focus has increasingly shifted towards the development of integrated sewage treatment equipment that offers advantages such as high treatment efficiency,reduced investment costs,small footprint requirements,low energy consumption,simplified operation and management processes,and a high degree of automation.Given the challenges posed by large dispersion characteristics,significant water change coefficients,limited water quantities,and low concentrations in treating rural domestic sewage;Combination technologies are currently receiving more attention with integrated sewage treatment equipment becoming an indispensable component within these processes.An analysis conducted on research papers from the CNKI database using scientific metrological visualization techniques reveals that since 2017 there has been substantial growth in research related to integrated sewage treatment equipment.
