Anti-blocking ecological filter dam for improving denitrifying effect of river

Abstract

The invention relates to an anti-blocking ecological filter dam for improving the denitrifying effect of a river. The anti-blocking ecological filter dam comprises a dam foundation, wherein four steelreinforcing rods are vertically, upwards and symmetrically welded in the middle of the dam foundation, gabion boxes are fixedly installed on the steel reinforcing rods, the cavity formed by the gabion boxes on the upstream face and the downstream face of a dam body and the dam foundation is filled with cobblestones, a gravel filling chamber made from separation nets in the middle of the dam bodyis filled with gravels, a filler frame formed through building wall type building is arranged in the dam body close to the gravel filling chamber and is filled with a plurality of filler balls, the filler balls are filled with ecological matrix particles, double layers of porous water distribution pipes are horizontally installed on the cobblestones on the upstream face and the downstream face ofthe dam body in the waterflow direction, and the water distribution pipes are provided with valves on inlets formed in the upstream face and outlets formed in the downstream face. The anti-blocking ecological filter dam is simple in structure, improves a denitrification effect, can increase the effective volume and prevent blockage and has good economic and social benefits.

Description

technical field [0001] The invention relates to environmental protection of rivers, in particular to an anti-clogging ecological filter dam which can enhance the removal effect of ammonia nitrogen in slightly polluted water bodies such as rivers and prevent clogging. Background technique [0002] Rivers give birth to cities and affect their development. However, with the rapid development of urbanization and industrialization, the discharge of sewage and waste water continues to increase, and the health of rivers is being seriously threatened. Excessive ammonia nitrogen content in rivers and lakes is one of the main problems of surface water environmental pollution. For many years, countries around the world have invested a lot of energy in the treatment of ammonia nitrogen pollution. However, ammonia nitrogen pollution in rivers and the environmental problems caused by it are still unresolved, which is the focus of human attention on water pollution restoration. One of the ...
