Rainwater filtering treater

Abstract

The invention relates to the technical field of water treatment and discloses a rainwater filtering treater. The treater comprises a filter cylinder and a precipitation cylinder, an abandoned flow pipe is arranged on the bottom of the filter cylinder, and the filter cylinder is connected with the precipitation cylinder through a flow guide pipe; a filter screen is arranged at the end, located in the filter cylinder, on the flow guide pipe, a water inlet pipe is arranged on the side surface of the filter cylinder, a water outlet pipe is arranged on the side surface of the precipitation cylinder, and the water inlet pipe and the water outlet pipe are higher than the flow guide pipe; a bearing plate is arranged in the filter cylinder, the top surface of the bearing plate is connected with theside wall of the filter cylinder through three springs, and a water outlet sleeve is arranged at the inner end of the water outlet pipe; an opening of the water outlet sleeve is toward the top surface of the bearing plate, a sliding rod is arranged in the center of the bearing plate, and the upper end of the sliding rod penetrates through the bearing plate and is slidingly connected with the bearing plate; a limit ball is arranged at the upper end of the sliding rod, and a counterweight ball which is used for sealing the abandoned flow pipe is arranged at the lower end of the sliding rod. Therainwater filtering treater has the advantage of filtering treatment of rainwater abandoned flow and rainwater.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a rainwater filter processor. Background technique [0002] The shortage of fresh water resources is a serious problem facing the world at present, and fresh water resources are highly valued by various countries. Rainwater is a very good freshwater resource. The natural rainwater has good water quality. During the rainfall process, the rainwater falls on the surface and scours the surface. Therefore, the initial rainwater contains a large amount of pollutants. As the rainfall continues, the rainwater runoff The pollutant content gradually decreased and tended to be stable. Taking advantage of this rule, the current rainwater treatment system usually uses a rainwater discarding device to discard the rainwater with more pollutants in the early stage, and collect the rainwater in the middle and late stages for domestic water use. At present, the rainwater abandonment devi...

AI Technical Summary

Problems solved by technology

At present, the rainwater abandonment device is mechanically discarded based on the principle that the initial rainwater flow is small. However, the common abandonment device cannot filter the pollutants in the middle and late rainwater. After the abandonment, the rainwater needs to be filtered again deal with
