Abstract

The invention discloses a sewage treatment system for river ways in a city. The system comprises a sewage pond, a stop net for filtering away suspension and chemical matter in sewage, an adjusting pond, a concrete pond, a settling pond, an anaerobic pond, an aerobic pond, an anoxia pond and a filter device. Microbial flora is added into the anaerobic pond. Nitrosomas and nitromonas are added into the aerobic pond. Denitrification bacteria are added into the anoxia pond. A filter layer, an adsorption layer, a filler layer and a heavy metal absorption layer are sequentially arranged in the filter device from bottom to top. The top of the filter device is connected with a micro-ecological filter pond through a drain pipe. By means of the sewage treatment system and a technology for river ways in the city, water body conditions are analyzed, and ecological regulation and control are achieved; by means of the method of combining exogenous pollution control, endogenous pollution control and micro-ecological system repair, the pollution problem of river ways in the city can be effectively solved, and a good pollution treatment effect is achieved. The invention further discloses the sewage treatment technology for river ways in the city.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and a sewage treatment process for urban inner waterways. Background technique [0002] With the development of the economy and the advancement of urbanization, the discharge of industrial sewage and domestic sewage is also increasing year by year. Generally, there are many enterprises around the rivers in the city, including leather factories, waste engine oil processing factories, electroplating factories and other heavily polluting industries. These enterprises are basically heavy polluting enterprises, such as leather wastewater, with large fluctuations in water quality and quantity, high concentration of suspended solids, easy corruption, large amount of pollution, and wastewater containing toxic compounds such as nitrogen, phosphorus, sulfide and cadmium. The oil spill from the waste engine oil factory also pollutes the water very seriousl...
