Water quality improvement method of static landscape water system

Abstract

The invention discloses a water quality improvement method for a static landscape water system. The water quality improvement method comprises the following steps that 1, dredging work is conducted on the bottom of a riverway; 2, new riverways are formed or culvert pipes are buried between the adjacent and independent riverways so as to allow all the riverways to communicate with each other; 3, aeration devices are laid at the bottoms of the riverways; and 4, a fountain is arranged in a scenic spot with a large pedestrian volume to improve the ornamental value and enhance the oxygen content and water fluidity of a water system; 5, submerged plants are planted at the bottoms of the riverways, fir piles are arranged along river banks to form revetments used for planting emergent aquatic plants, and after the submerged plants and the emergent aquatic plants are planted, water is returned to the riverways, an ecological floating bed is added to a river surface, and aquatic animals and microorganisms are put into the river surface; and 6, rainwater purification wetlands are arranged on the riverway located at a lower terrain in the length direction of the riverway. According to the invention, single riverways are allowed to communicate with each other to form a complete dynamic water system, so the whole water system is in single water quality, the self-purification capacity of the water body is improved, and water purification difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of landscaping and environmental protection, and in particular relates to a method for improving water quality of a static landscape water system. Background technique [0002] Water body is an important element of garden design. Landscape water body can not only decorate the environment, give people a sense of beauty, but also maintain ecological balance. Due to limited conditions, most of the landscape water bodies in gardens are formed by artificial excavation, and often exist in the form of static water features. The fluidity of static water features is not enough. A large amount of such pollutants and nutrients are also deposited in the silt at the bottom, which further increases the nutrient and pollution load of the water body. [0003] At present, there are physical methods, chemical methods and microbial methods to control the pollution of landscape water bodies. The above methods cannot improve th...

Due to limited conditions, most of the landscape water bodies in gardens are formed by artificial excavation, and often exist in the form of static water features. The fluidity of static water features is not enough. A large amount of such pollutants and nutrients are also deposited in the silt at the bottom, further increasing the nutrient and pollution load of the water body

[0003] At present, there are physical methods, chemical methods and microbial methods to control the pollution of landscape water bodies. The above methods cannot improve the self-purification ability of water bodies, and cannot fundamentally solve the pollution of landscape water bodies. The cost of treatment is high, and a large amount of manual participation is required. philosophy
