Example Embodiment

[0038] like figure 1 , figure 2 As shown, the present invention provides a regenerated water replenishment channel system based on river bank infiltration, including a rainwater discarded flow collection unit, a rainwater purification unit, a regenerated water replenishment unit, and a bank infiltration-biological treatment unit.

[0039] The rainwater waste flow collection unit includes a vegetation isolation section 7 , a rainwater waste flow device 33 , a rainwater collection green space 8 , a wire 55 , a first solenoid valve 52 , a second solenoid valve 53 , and a rainwater waste flow cavity 56 .

[0040] The vegetation isolation section 7 is composed of a soil layer 34 and arbors 28 . The lower stratum of the vegetation isolation section 7 is the undisturbed riparian soil layer 34, the upper part of the vegetation isolation section 7 is planted with arbors 28, and the vegetation isolation section 7 can initially intercept surface runoff. The rainwater collection green sp...

Abstract

The invention provides a reclaimed water supplementing riverway system and method based on river bank filtration. The system comprises a river bank filtration-biological treatment unit. A vertical anti-seepage layer is arranged on the side, away from a riverway, of the river bank filtration-biological treatment unit, revetment bricks are laid on the side, close to the riverway, of the river bank filtration-biological treatment unit, and an organic pollutant efficient removal layer, a denitrification layer and an aerobic nitrification layer are sequentially arranged between the revetment bricksand the vertical anti-seepage layer from bottom to top. The aerobic nitrification layer comprises a first multifunctional tube and mixed and laid gravels and modified zeolite. The denitrification layer comprises a second multifunctional tube and ceramsite, volcanics and iron-coated quartz sand symmetrically distributed from outside to inside. The organic pollutant efficient removal layer comprises a third multifunctional tube and mixed and laid gravels and modified zeolite. It can be avoided that eutrophication is caused when reclaimed water is supplemented to the riverway, and the underground water pollution risk caused by the supplementing of reclaimed water is reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a reclaimed water supply river channel system and method based on river bank infiltration. Background technique [0002] With the population growth and rapid economic development in our country, the demand for water resources is gradually increasing, and the situation of water resources is becoming increasingly severe. The frequent interruption of rivers in the north has caused a series of ecological environmental problems such as water pollution and ecological environment degradation. The water body that meets certain usage requirements after the sewage generated in production and life is treated is called "reclaimed water". Reclaimed water has great utilization potential and has become a reliable and stable water source to maintain the ecological water demand of northern rivers. As a new source of urban water supply, recycled water has a wide range of uses, such as agricultural...
