Rainwater purifying system

Abstract

The invention discloses a rainwater purification system, which comprises a water inlet pipe, a sedimentation tank, a multi-grid filter tank communicated with the sedimentation tank through a U-shaped pipe, and a clear water tank communicated with the multi-grid filter tank through a water outlet pipe. The sedimentation tank includes: biological filler pre-oxidation treatment tank; coarse sedimentation tank; fine sedimentation tank. There is a collection bucket at the bottom of the sedimentation tank, and an automatic sludge discharge valve is installed under the collection bucket. The interior of the multi-cell filter is equipped with a quartz sand layer and a clear water flow pipe pierced through the quartz sand layer. An automatic control cabinet connected to an automatic mud valve is installed on the outer top, and a chemical dosing device is also installed. The chemical dosing device passes through the first A connecting pipe communicates with the water inlet pipe. The rainwater purification system of the present invention has good rainwater purification effect, clear water outlet, and qualified water quality sanitation index. At the same time, it also saves the cost of chemicals, occupies less land, and is convenient for operation, maintenance and management.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rainwater purification system. Background technique [0002] At present, the lack of water resources has become a worldwide problem. When the traditional water resources development methods can no longer increase water resources, recycling rainwater has become an economical and practical way of water resources development. As a precious water resource, rainwater has been recognized by countries all over the world. The rainwater collected and utilized can replace tap water within a certain range to alleviate the shortage of urban water resources, and at the same time reduce the load on urban sewage pipe networks to a certain extent. The pollution of roof rainwater is relatively light, and the treatment cost is low, so it should be the main object of our collection and utilization. [0003] The utilization and resource utilization of urban rainwater are very common in ...
