Primary filtering device for environment-friendly rainwater treatment and using method thereof

Abstract

The invention discloses a primary filtering device for environment-friendly rainwater treatment and a using method thereof. The primary filtering device comprises a device base, and a filtering box body is installed on the device base; and two groups of partition plates are arranged in the filter box main body, wherein the interior of the filter box main body is divided into three groups of first filter tanks, second filter tanks and third filter tanks with the same size and structure by the two groups of partition plates, and filter screens are arranged on the first filter tanks, the second filter tanks and the third filter tanks, and the diameters and densities of filter holes of the three groups of filter screens are different. According to the invention, the three groups of filter screens are arranged in the filter box main body to perform multi-stage filtration on rainwater, so that the rainwater filtration and purification effect is gradually improved; meanwhile, three groups of pipeline filters corresponding to the filter tanks are arranged to further perform filtration and purification on the rainwater, and chemical reagents are respectively added into the three groups of filter tanks to perform reaction and purification on the rainwater. Therefore, physical and chemical purification of rainwater is realized, and the primary filtration and filtration treatment efficiency of rainwater is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection and filtration, and in particular relates to a primary filter device for environmental protection rainwater treatment and a use method thereof. Background technique [0002] In the modern urban landscape, natural approaches and artificial measures should be considered comprehensively in terms of water resource recycling. We need to maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and waterlogging, and promote Utilization of rainwater resources and ecological environment protection, coordinate the systematic nature of natural precipitation, surface water and groundwater, coordinate water supply, drainage and other water recycling links, and consider its complexity and long-term nature. Collect and purify the rainwater through the rainwater purification device to meet the design and use standards...

AI Technical Summary

Problems solved by technology

[0003] After the rainwater is collected, it needs to be purified. Before the purification, the rainwater is generally filtered to remove the sundries that are easy to remove in the rainwater. However, the existing filter device has poor purification and filtration effect on the rainwater, and there is no cleaning device in the filter device. The component cleans the inside. When the device is used for a period of time, there are filtered debris inside, and it cannot be cleaned in time, which will affect the filtering effect on water quality.
