Abstract

The rain water recovering and utilizing apparatus for factory area includes production waste water and rain water collecting pipeline connected through regulating water pond to the rain water draining pipeline, deposit tank connected to the rain water draining pipeline, rain water backing and lifting pump inside the deposit tank, rain water backing pipeline with one end connected to the rain water backing and lifting pump and the other end connected to the regulating water pond, the lifting pump in the regulating water pond and connected to the waste water treating unit, and back water pump in the water backing pond and connected to the back water pipeline. The present invention is especially suitable for where water resource is lacked and there is relatively high environment protection requirement.

Description

Technical field: [0001] The invention relates to a rainwater recycling device in a factory area. Background technique: [0002] At present, there are two ways to configure the rain drainage system in the factory. One is to set up the rain drainage system separately and discharge the collected rainwater directly to nearby rivers or lakes; the other is to combine the rain drainage system with production or domestic drainage. The system is jointly built, and interception wells are set at the end of the pipe network, and the production or domestic sewage and the intercepted initial rainwater are sent to the sewage treatment station for treatment. Most of the rainwater and the sewage and waste water mixed in the rainwater are directly discharged to nearby rivers or lake. For the first method, all the sewage and waste water are sent to the sewage treatment station for treatment, which will not pollute the nearby rivers or lakes, but the initial rainwater also contains certain pol...
