specific Embodiment approach 1

[0012] Specific implementation mode one: (please refer to the attached figure 1 ) The artificially reinforced ecological filter bed of the present embodiment comprises a water inlet area 1, a filter bed 3 and a water outlet area 5, the water inlet area 1 and the filter bed 3 are separated by the first overflow wall 2, and the filter bed 3 and the water outlet area 5 are separated by the first overflow wall 2. The two overflow walls 4 are separated, the water inlet pipe 6 is arranged on the upper part of the side wall of the water inlet area 1, the water outlet pipe 7 is arranged on the lower part of the side wall of the water outlet area 5, and the filter bed 3 is equipped with a volcanic rock filter material 8 with a particle size of 70 mm to 100 mm. The filling height is three-quarters of the height of the filter bed 3, and the filter bed 3 is divided into anaerobic zone 3-1, aeration zone 3-2 and anoxic zone 3-3 along the water flow direction, and the bottom of anaerobic zon...

specific Embodiment approach 2

[0014] Embodiment 2: This embodiment differs from Embodiment 1 in that: the particle size of the volcanic rock filter material 8 in the filter bed is 75 mm to 95 mm. Others are the same as the first embodiment.

[0015] The particle size of the volcanic rock filter material 8 adopted in this embodiment can make the water flow in the filter bed unimpeded and blockage is not easy to occur.

specific Embodiment approach 3

[0016] Embodiment 3: This embodiment is different from Embodiment 1 in that: the particle size of the volcanic rock filter material 8 in the filter bed is 85mm. Others are the same as the first embodiment.

Abstract

The invention relates to an artificial reinforced ecological filter bed, and a method for treating polluted river water through the artificial reinforced ecological filter bed. The invention relates to an artificial reinforced ecological filter bed, and a method for treating polluted river water through the artificial reinforced ecological filter bed. The invention solves the technical problems that the existing river water distribution method and the ecological floating islands have narrow application ranges; the existing aeration method applicable to river ways has a high operating cost; and the existing river water distribution method, the ecological floating islands and the aeration method applicable to river ways are not suitable for treating rural river water polluted seriously. Theartificial reinforced ecological filter bed is divided into a water inlet zone, a filter bed and a water outlet zone through overflow walls. The filter bed is loaded with volcanic rock filter material and is divided into an anaerobic zone, an aeration zone and an anoxic zone. A perforated aeration pipe is arranged at the bottom of the aeration zone. The bottom of the anaerobic zone is provided with a mud bucket and a mud discharge pipe, and so does the anoxic zone. The method for treating polluted river water through the artificial reinforced ecological filter bed comprises building a surfaceplug flow wetland and an artificial reinforced ecological filter bed on a riverbed and introducing river water into the surface plug flow wetland and the artificial reinforced ecological filter bed to carry out a treatment on the introduced river water. The artificial reinforced ecological filter bed has a low building cost, is convenient for running and maintenance and is suitable for treating rural cross-border rivers and river water polluted seriously.

Description

technical field [0001] The invention relates to a filter bed and a method for controlling polluted river water. Background technique [0002] With the development of industry, agriculture and animal husbandry, the waste water produced is directly or indirectly discharged into the river, causing the river to be polluted. At present, the river water distribution method adopted for the treatment of polluted rivers cannot implement source control and water distribution technologies in a certain area for rural cross-border rivers and heavily polluted rivers; and the river aeration method is too expensive to operate and is not suitable for rural areas. The treatment of polluted river water; while the ecological floating island method is only suitable for the treatment of low-pollution river water, and the restoration effect for heavily polluted rivers is not significant. Contents of the invention [0003] The present invention aims to solve the technical problems that the exist...
