Initial rainwater separation and purification integrated device and using method thereof

Abstract

The invention discloses an initial rainwater separation and purification integrated device and a using method thereof, and belongs to the field of ecological environment. A rainwater collection pipeline and a subsequent rainwater treatment pipeline are arranged on the two sides of a double-layer stainless steel filter screen of the device respectively, and a floating ball is placed in a sewage storage tank. The double-layer stainless steel filter screen can intercept solid impurities in rainwater, and meanwhile, a mixture of activated carbon and alkaline substances in the filter screen can play a certain role in purifying the collected rainwater. The storage water level of initial rainwater in the sewage storage tank drives the floating ball to rise, and finally the floating ball blocks asewage inlet of a hose to prevent rainwater from entering in the middle and later periods. The rainwater in the middle and later periods can be further purified or directly discharged into the environment after flowing into the subsequent rainwater treatment pipeline, so that the initial rainwater and the rainwater in the middle and later periods can be automatically separated. The device is simple in structure, can normally work without other external power, reduces the times of manual maintenance, and is suitable for various ways of rainwater recycling.

Description

technical field [0001] The invention belongs to the field of ecological environment, and in particular relates to a device system integrating initial rainwater separation and purification without external power for automatic separation and purification. Background technique [0002] my country's water resources are scarce, and the current situation of water environment pollution is severe. Both resource-related water shortages and water-quality water shortages are equally important, and both of them restrict the sustainable development of economy and society at the same time. In addition, rainwater is a high-quality fresh water resource, which has a large amount, is easy to collect, and has low purification costs, so it has gradually been valued by people. Recycling rainwater has become an economical and practical way to develop water resources, and it is an important measure to solve urban water shortage and flood control problems. However, with the rapid development of Ch...
