Embodiment Construction

[0022] The present invention aims to build a systemic and efficient sponge wetland system, which organically combines source control and interception, internal source treatment, water quality purification, and ecological restoration, taking into account both landscape effects and ecological benefits, and improving the purification effect of urban water bodies. It also increases the landscape of the artificial wetland and forms a comprehensive wetland garden project.

[0023] Such as figure 1 and figure 2 As shown, the sponge wetland system of the present invention includes a rainwater wetland garden 2, a grass planting ditch 3, a rainwater collection adjustment pond 4, an intensive treatment deep water area 5 and a shoal ecological area 6. The rainwater wetland garden 2 is built on a higher overall terrain in the entire sponge wetland system (wetland garden), and is connected to each other through the grass planting ditch 3 . The grass planting ditch 3 is connected with the...

Abstract

The invention discloses a sponge wetland system. The sponge wetland system comprises rainwater wetland gardens, grass planted ditches, rainwater collecting and adjusting tanks, an enhancement treatment deepwater area and a shallow ecotope, wherein the rainwater wetland gardens are connected with one another through the grass planted ditches, the grass planted ditches are connected with the rainwater collecting and adjusting tanks, the building terrains of the rainwater wetland gardens are higher than those of the rainwater collecting and adjusting tanks, the rainwater collecting and adjustingtanks are connected with the enhancement treatment deepwater area, effluent valves are arranged at the communicated positions, and the shallow ecotope is arranged on the periphery of the enhancement treatment deepwater area. According to the sponge wetland system, measures of penetration, retention, impoundment, purification, recycle, stabilization and the like are integrated, water yield and water quality impact of rainfall runoff on a constructed wetland is reduced, retention time of rain sewage is prolonged, the treatment efficiency is improved, meanwhile, a seasonal sponge wetland landscape is created, and not only are purposes of aquatic environment purification and aquatic ecological rehabilitation achieved, but also the landscape performance of a wetland garden is improved; source controlling, sewage intercepting, endogenous treating, water quality purifying and ecological rehabilitating are conducted on a target water body, and the rainwater storing, throttling and purifying capability and the wetland stability are improved.

Description

technical field [0001] The invention relates to an artificial wetland system for rainwater treatment, belonging to the technical field of ecological environment water treatment. Background technique [0002] Constructed wetlands are artificially designed systems that purify receiving water bodies through physical, chemical, and biological treatments. According to different water distribution methods, they are generally divided into three types: horizontal subsurface flow wetlands, vertical subsurface flow wetlands, and surface flow wetlands. Compared with the traditional water treatment process, the constructed wetland sewage treatment system has low construction and operation costs, has a certain buffer against hydraulic and pollution load impacts, and is easy to maintain, but at the same time has a low concentration of influent pollutants and a large footprint. shortcoming. Constructed wetland ecosystems have been widely used in recent years to treat rural domestic sewage...
