Complete technology for resource utilization of rainwater

Abstract

The invention relates to a complete technology for resource utilization of rainwater. The complete technology comprises the steps of: purifying rainwater from different underlaying surfaces by adopting split-flow and filtering methods, disinfecting, and combining the clean rainwater with a tap water or reclaimed water supplying system so as to realize resource utilization of the rainwater. According to the invention, pipelines/channels are used for sequentially connecting a rainwater overflow well, a rainwater grid well, a rainwater sedimentation tank, a rainwater split-flow tank, an inspection well, a regulation and storage tank and a clean water tank; a lift pump lifts rainwater in the rainwater clean water tank to an elevated water tank, the bottom of the elevated water tank is connected with the bottom of a mechanical filter through a pipeline, the top of a mechanical filter is sequentially connected with a filter pump and the regulation and storage tank through pipelines, and a disinfecting tank passes through a tee pipe and is respectively connected with the clean water tank and the mechanical filter by related pipeline systems so as to jointly form a rainwater colleting system, a high-efficiency purifier, a rainwater recycling system, a rainwater treatment system and a chemical feeding disinfection system.

Description

technical field [0001] The invention relates to a complete set of technology for resource utilization of rainwater, which adopts the method of discarding and filtering to purify rainwater on different underlying surfaces, and after disinfection, the clean rainwater is combined with tap water or a reclaimed water supply system to realize resource utilization of rainwater. The utility model belongs to the technical field of rainwater recycling and environmental protection. Background technique [0002] From the existing research results, we can see that the rainwater purification technology mainly includes coagulation sedimentation and filtration. [0003] The coagulation-sedimentation technology mainly has the following problems: First, the technology itself has many steps. In order to achieve a good purification effect, the structure of each equipment is complex, difficult to manufacture, difficult to clean and maintain, which is not conducive to technology promotion. Secon...

Problems solved by technology

[0003] The coagulation-sedimentation technology mainly has the following problems: First, the technology itself has many steps. In order to achieve a good purification effect, the structure of each equipment is complex, difficult to manufacture, difficult to clean and maintain, which is not conducive to technology promotion

[0005] At present, the research time on rainwater in China is relatively short, and each researcher only studies one aspect of rainwater resource utilization. Sheng Mingjun researched and developed the water quantity, water quality and combined regulation, storage and treatment facilities for the west trunk line system in Shanghai. Coagulation and sedimentation process of rainy day overflow sewage in dry cleaning system and on-site efficient treatment device for overflow sewage
