Background

The rainwater treatment is a purification treatment process of ground runoff water (rainwater, snow melt water and watering) in urban areas.

According to different drainage systems (split system or combined system) of the pipeline system, the rainwater treatment can be carried out independently or combined with domestic sewage and industrial wastewater for treatment. The water quantity of the rainwater treatment is calculated according to the rainwater channel (according to the dilution multiple or the water quantity of a rainwater pump station), but a rainwater regulating pool is preferably arranged before the rainwater enters the treatment structure. The rainwater quality can adopt: BOD 20-80 mg/L, SS 150-300 mg/L, and oil 8-18 mg/L. When rainwater is treated separately, a rainwater collecting and precipitating pond (pond) is always arranged, a grid is arranged in front of the pond, and a filter pond can be arranged behind the pond. The flow rate of water in the pool is less than 0.01m/s, the retention time is not less than 1-2h (the water volume can reach 2-5 days and nights), and the BOD can be reduced by 50-70% after treatment. When the sewage is combined with domestic sewage and industrial wastewater for treatment, the water quantities of the grating and the grit chamber are calculated according to the sum of the total water quantity, and the retention time in the sedimentation tank is not less than 1 h. The aeration tank can not treat the rainwater or treat partial rainwater according to the calculation, and the volume of the sludge deposition and treatment part is calculated according to the sum of the sludge amount. And if the treated rainwater is used for industrial circulating water, the treatment requirement is calculated according to the quality of the circulating water. The discharge port after the rainwater is treated can be arranged on the bank of the water body according to the condition.
