Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the initial rainwater is discharged arbitrarily, but the existing drainage system cannot handle the polluting initial rainwater, which causes a lot of pollution. Therefore, a filter device for the buried initial rainwater treatment system is provided

Embodiment Construction

[0018] The present invention is described in detail below in conjunction with accompanying drawing:

[0019] like figure 1 As shown, a buried rainwater purification integrated system includes a casing 7 buried in the ground, a water inlet 1 is provided on one side of the casing 7, and a water outlet 5 is provided on the opposite side. The housing 7 is provided with a filter tank 2 with sand, a filter tank 3 with plastic biological filter material and a permeable grid 4 in sequence along the direction of water flow.

[0020] The biological filter material is fly ash plus activated carbon, and the fly ash is an active oxide SiO 2 and Al 2 o 3 It is mainly a powdery substance with porosity and a large specific surface area. It can remove ammonia nitrogen and phosphorus in domestic sewage through adsorption and ion exchange.

[0021] The biological filter material is fly ash plus carbonized straw. Using straw to make biomass carbon particles, fly ash and carbonized straw have...

Abstract

The invention discloses an underground rainwater purifying integral system, comprising a shell buried underground. A water inlet is formed in one side of the shell, a water outlet is formed in the opposite side of the shell, a filter tank filled with sand, a filter tank filled with a plastic biofilter material and a water permeating grate are sequentially arranged in the shell along a water flow direction. The underground rainwater purifying integral system can effectively reduce solid particles in initial rainwater and ammonia, nitrogen and phosphorus in the initial rainwater; the ammonia, nitrogen and phosphorus can be returned to a field after adsorption of an adsorbant.

Description

technical field [0001] The invention relates to an underground buried rainwater purification integrated system, which is generally installed on urban river pipes or rainwater pipes, and is suitable for the occasion of treating initial rainwater, belonging to the technical field of water treatment. technical background [0002] Due to the prominent contradictions in our country's environmental pollution problems, the phenomenon of smog has become quite common in recent years, and the degree of smog has become more and more serious. The country and the people have begun to attach great importance to it, especially water environment problems, which have a huge impact on people's lives, and some have seriously affected people. health. In the early stage of rainfall, a large amount of acid gas in the air, car exhaust and other polluting gases were dissolved. After landing on the ground, the asphalt concrete road was washed away, and the sewage, sludge and garbage accumulated in t...
