Abstract

The invention discloses a hydroponic plant and filter dam combined eutrophication water body ex-situ remediation system. The system consists of a water inlet and diversion system, a water dropping platform, a coarse sand-cress composite ecological filter dam, a fine sand-coal ash-ryegrass composite ecological filter dam, a fine sand-bermuda grass filter dam and a water outlet and diversion system; the water inlet and diversion system consists of a water elevator and a water distribution channel; the water outlet end of the water elevator is arranged in the water distribution channel; the water discharge end of the water distribution channel is sequentially provided with the water dropping platform, the coarse sand-cress composite ecological filter dam, the fine sand-coal ash-ryegrass composite ecological filter dam, the fine sand-bermuda grass filter dam and the water outlet and diversion system; the water discharge end of the water distribution channel is communicated with the water inlet end of the coarse sand-cress composite ecological filter dam through the water dropping platform; and the system has a simple structure, and is low in running management cost, and good in effect, can adapt to purifying water in heavily contaminated urban riverway, and remediating the water quality of slightly contaminated riverways, and is strong in adaptability.

Description

[0001] Technical field [0002] The invention relates to a restoration system suitable for eutrophic water bodies in urban rivers, in particular to an ex-situ restoration system for eutrophic water bodies combining hydroponic plants and filter dams. Background technique [0003] The urban river system is an important ecological landscape in cities and towns, which is of great significance to improving the urban ecological environment and the quality of life of residents, and the water quality of the river system will be the key to its effect. Due to the proximity to residential areas, or passing through the city or passing through the city, the water quality of urban rivers deteriorated by long-term interference by residents is a very common phenomenon in large and small cities throughout my country. In some southern cities, such as Wuxi, Suzhou, Changzhou and other cities with dense river networks, their urban rivers have been polluted for a long time, and the water quality has d...
