Water quantity balancing and water quality improvement system for garden landscape water body

Abstract

The invention relates to a water quantity balancing and water quality improvement system for a garden landscape water body. The system comprises a rain sewage interception unit, an underground water storage unit, an artificial wetland purification unit and an ecological clear water recycling unit. The rain sewage interception unit conveys intercepted rain sewage to the underground water storage unit for storage, and meanwhile water in the rain sewage interception unit is conveyed to the constructed wetland purification unit for purification. The underground water storage unit conveys rain sewage to the constructed wetland purification unit for purification, and ecological clear water obtained after purification treatment is conveyed to the ecological clear water recycling unit for use. Rainwater is intercepted through constructed wetland treatment, and pollutants entering the landscape water body are reduced from the source; effluent of the constructed wetland can be recycled in the garden, so that the water balance of the whole garden water system is guaranteed, and the trouble of frequent water supplementation is avoided; the underground water storage unit can be used for storingwater for buffering, and rainwater is collected for treatment in rainy days.

Description

Technical field [0001] The invention relates to the technical field of landscape water treatment, in particular to a water balance and water quality improvement system for garden landscape water bodies. Background technique [0002] As a landscaping element, the landscape water in the garden not only has ecological value, but also can adjust temperature and humidity, purify the air, and enhance comfort. However, the garden landscape water body is a closed water area, which generally has the characteristics of small water area, easy pollution, small water environment capacity, and low self-purification ability of the water body. Landscape water bodies usually still have water leakage. Coupled with evaporation, it is often necessary to use river water or tap water as a supplementary water source, which increases maintenance costs. The existing garden landscape water treatment technologies mainly include aquatic animal and plant restoration, sterilization and algaecide, microbes, a...

AI Technical Summary

Problems solved by technology

The existing landscape water treatment technologies mainly include aquatic animal and plant restoration, bactericidal algaecide, microorganisms, and rainwater interception treatment; the in-situ treatment of aquatic animals and plants has little effect, and the application of chemicals can have a weak effect for a short time, but not for a long time. , The rainwater interception technology cannot solve the problems of poor circulation and pollutants in the water body itself

These technologies usually only solve one of the problems of poor circulation or high pollutant load in the landscape water body, and cannot comprehensively and systematically solve the problem of water quality and water volume balance in the landscape water body
