Abstract:
A rainwater sewage interception method based on a membrane separation technique, comprising the following steps: intercepting collected sewage, and discharging the intercepted sewage to a sewage treatment plant; overflowing sewage exceeding the intercepting capacity of an intercepting well, and enabling the overflowing sewage to enter a membrane separation device; filtering the overflowing sewage by means of the membrane separation device to form filtered water, and discharging the filtered water to a filtered water reservoir; and controlling the membrane separation device to discharge the filtered water to the filtered water reservoir when the water level of the filtered water reservoir is lower than the water outlet level of the membrane separation device. The method can be widely applied to municipal drainage, water body protection, water environment restoration, etc., and is used for the removal of pollutants, such as particulates, suspended matters, organics and heavy metals, from water, thus achieving the purpose of water body protection.
