In-situ ecological purification module and system for polluted water treatment

Abstract

The invention discloses an in-situ ecological purification module and system for polluted water treatment. The in-situ ecological purification module comprises a planting groove system, a suspended filler system and a fixed filler system. The planting groove system comprises a planting groove and a first filler, and hygrophytes or aquatic plants are planted in the planting groove system. The suspended filler system comprises a supporting frame, a second filler and a mounting auxiliary material. The fixed filler system comprises a gabion net and a third filler. The supporting frame is fixed in river sediment, the planting groove is formed in the top of the supporting frame, and the fixed filler system is arranged at the bottom of the supporting frame. The in-situ ecological purification module and the in-situ ecological purification system can be applied to in-situ water purification of a seriously polluted river channel or a broken river channel without water source supply, have an ecological landscape effect, adopt modular design, and are simple in structure and convenient to assemble, disassemble, transport and operate, maintain and manage.

Description

technical field [0001] The invention relates to the technical field of purification of polluted water bodies, in particular to an in-situ ecological purification module and system for treating polluted water bodies. Background technique [0002] With the acceleration of urbanization, the problem of water pollution has become more and more prominent. It threatens people's production and life. Uninterrupted sewage and non-point source pollution flow into natural water bodies such as rivers. The pollution load of rivers increases and exceeds the capacity of the water environment. The system is damaged, the self-purification ability is poor, and the water quality has been polluted for a long time. Water resource protection and water pollution control must be carried out simultaneously. [0003] At present, in-situ restoration technologies for river courses include ecological floating islands, adding microbial agents or enzyme preparations, and plant ecological restoration. Each...

AI Technical Summary

Problems solved by technology

[0003] At present, in-situ restoration technologies for river courses include ecological floating islands, adding microbial agents or enzyme preparations, and plant ecological restoration. Each technology has its own advantages, but there are also deficiencies. Due to the influence of environmental conditions, the purification ability of some plants is limited or the plants cannot grow normally under low temperature conditions, resulting in poor purification effect on water pollutants; adding microbial agents or enzyme preparations, because the river is flowing, non-stationary water, free Microorganisms or enzyme preparations flow downstream with the water, failing to guarantee a certain residence time, and the purification effect is not ideal; plant ecological restoration, a single ecological restoration measure has limited effect on the treatment of heavily polluted water bodies
