Abstract:

The urban characteristics, regional characteristics, and sewage treatment system of a city in the lower reaches of the Yangtze River are analyzed and evaluated. The comprehensive measures to improve the quality and efficiency of sewage are put forward based on the problem. The urban sewage environment, drainage system, sewage collection pipe network, sewage treatment plant and other sewage treatment status are comprehensively analyzed. The "three-elimination", "three-treatment" and "three-improvement" implementation schemes are put forward. "Three eliminations" include the elimination of urban black and odorous water bodies, straight sewage outlets and empty areas in the pipe network. "Three treatments" include the treatment of industrial and enterprise drainage, "small scattered" drainage, and balcony and unit courtyard drainage. "Three improvements" include the improvement of the comprehensive capacity of urban sewage treatment, the quality control of the sewage pipe network, and the detection, repair and maintenance management levels of the pipe network.
