Problems solved by technology
[0005] Based on the background technology, but the current township sewage treatment is not perfect, there is no targeted treatment of sewage according to the characteristics of township sewage flow and water quality with large seasonal fluctuations, resulting in poor sewage treatment effect or heavy load on weekdays It still operates normally when it is small, and there are technical problems such as huge waste of energy consumption and high treatment cost. The present invention proposes a sewage treatment process based on the seasonal fluctuation of sewage flow and water quality

The invention belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment process based on seasonal fluctuation of sewage flow and water quality. The sewage treatment process comprises a normal mode, an SBR mode and an emergency mode. The normal mode is suitable for areas with small water quantity fluctuation, and the normal mode an AAO operation mode. The SBR mode is suitable for areas with small daily flow and sharp water increase in holidays and festivals. The emergency mode is suitable for areas where the daily flow is sufficient and the water volume is sharply increased in festivals and holidays. The normal mode is characterized in that each module device is integrated in an independent module, and a device control box body does not need to be additionally arranged. By setting the normal mode, the residence time of each process section can be adjusted according to the water quality and water quantity of inlet water, the denitrification efficiency can be improved as required, and according to the actual water quality and water quantity of the inlet water, required modules are added for capacity expansion by utilizing the redundancy processing capability of the modules, and the processing capacity and the impact load resistance of equipment can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment process based on seasonal fluctuations of sewage flow and water quality. Background technique [0002] Township sewage is very different from urban sewage. First, towns and cities have great differences in social, economic and technical conditions; second, the physical and chemical indicators of township sewage and urban sewage are also different. Therefore, the relatively mature urban sewage treatment process is not applicable to townships. [0003] The rural economy develops rapidly, and the living standard of farmers improves rapidly, but the development of the rural economy brings environmental pollution, and the water environment pollution is particularly serious. Untreated domestic sewage is discharged randomly, causing the water quality of ditches and ponds to turn black and smelly, breeding mosquitoes, affecting the living environment in rura...
