Sponge type composite ecological side slope water body purification system

Abstract

The invention discloses a sponge type composite ecological side slope water purification system. The system comprises sponge type composite flow artificial rapid infiltration ecological side slope systems and sponge type wetland ecological side slope systems which are arranged at intervals along a side slope, and a water distribution side ditch formed in the tops of the sponge type composite flowartificial rapid infiltration ecological side slope systems and the sponge type wetland ecological side slope systems, wherein each sponge type composite flow artificial rapid infiltration ecologicalside slope system comprises a rapid infiltration filler layer, a geotextile filter screen inverted filter layer, a pebble protective layer, a perforated drainage pipe and a concrete foot groove whichare arranged along the side slope, and the perforated drainage pipe is arranged at the bottom end of the side slope; each sponge type wetland ecological side slope system comprises a concrete foot groove formed in the bottom end of the side slope and a plant substrate layer arranged along the side slope, and landscape greening plants are planted on the plant substrate layer; and a security filterlayer is arranged in the water distribution side ditch, and perforated guide plates are arranged at the joints of the water distribution side ditch and the sponge type composite flow artificial rapidinfiltration ecological side slope systems. The sponge type composite ecological side slope water purification system is arranged along the side slope, does not need extra land occupation, and is highin treatment efficiency, convenient to operate and manage and low in operation cost.

Description

technical field [0001] The invention relates to a sponge type composite ecological slope water body purification system, which belongs to the technical field of water treatment. Background technique [0002] In recent years, the problem of environmental pollution of rivers and lakes has become increasingly prominent. There has been no good treatment ideas and technologies for non-point source pollution such as initial rainwater around rivers and lakes and tail water from sewage plants. The conventional initial rainwater measure is to build a new initial rain storage tank for storage, and later upgrade it to a sewage plant for treatment. This solution requires the construction of a larger storage tank, which has many disadvantages such as high investment, large footprint, and affecting the normal operation of the sewage plant. . The tail water of the sewage plant is still inferior to Class V water, and it will be discharged into rivers and lakes in a concentrated manner, whi...

[0002] In recent years, the environmental pollution of rivers and lakes has become more and more prominent. There has been no good treatment ideas and technologies for the non-point source pollution such as initial rainwater around rivers and lakes and the tail water of sewage plants.

The conventional initial rainwater measure is to build a new initial rain storage tank for storage, and later upgrade it to a sewage plant for treatment. This solution requires the construction of a larger storage tank, which has many disadvantages such as high investment, large footprint, and affecting the normal operation of the sewage plant.

The tail water of the sewage plant is still inferior to Class V water, and it will be discharged into rivers and lakes in a concentrated manner, which will cause great harm to the water environment of rivers and lakes
