Garden rainwater collection system

Abstract

The invention discloses a garden rainwater collection system. The system comprises a primary filter tank, a sedimentation tank, a laminated compounded filter tank; the primary filter tank is internally provided with a first separator plate and an inclined filter grid for separating the primary filter tank into a filtrate collecting zone and a primary sedimentation zone; the filtrate collecting region is internally provided with a base plate and a filter basket, and a sewage zone whose bottom is connected to a sewage pipe is formed at the lower area of the base plate; the sedimentation tank isconnected to the primary sedimentation zone through a first water pump and a pipeline, the sedimentation tank is internally provided with a fixed plate for separating the sedimentation tank into a sedimentation zone and a sludge zone, and the sedimentation zone is internally provided with an inclined tube sedimentation component; the filter tank is connected to the sedimentation zone by a second water pump and a pipeline, the filter tank is internally provided with a second separator plate for separating the filter tank into a filtering zone and a water collecting zone, a water outlet is arranged between the second separator plate and the bottom of the filter tank, and support plates and a composite filter layer are arranged in the filtering zone. The system has the advantages of low operation cost, stable and smooth water outlet, long usage time, good rainwater purifying effects, and reduced water cost of the garden.

Description

technical field [0001] The invention relates to the technical field of garden rainwater recycling and utilization, in particular to a garden rainwater collection system. Background technique [0002] Rainwater is an abundant freshwater resource. At present, when it rains, the surface rainwater on the garden green space directly infiltrates into the soil or is directly discharged into the sewer from the drain outlet after confluence by ditches. The rainwater directly infiltrates into the soil and cannot be stored for a long time, resulting in a great waste of water resources. The rainwater on the surface of the green space contains a lot of sundries such as leaves, branches, weeds, soil, stones and so on. If it is directly discharged into the sewer, it will easily cause the drainage hole of the inspection manhole cover at the sewer mouth to be blocked. [0003] For example, the application publication number CN106638899A, the Chinese patent of application publication date 20...

Problems solved by technology

When the garden collection system is in use, the filtered debris will accumulate on the rainwater filter cover to block the filter holes of the filter cover, resulting in poor water filtration and affecting the filtering effect
