Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.
[0024] Such as figure 1 , figure 2 and image 3 As shown, the land treatment system is a tank with a trapezoidal cross-section, which can be excavated below the ground, with an anti-seepage film 8 laid around and at the bottom. From bottom to top, there are sand layer 9, water distribution layer 10, biological filler and The water collection layer 11, the soil layer 12, and the water collection vertical pipe 15, the water collection horizontal pipe 5, the water collection branch pipe 6 and the water collection main pipe 13 laid in the biological filler and the water collection layer 11. The anti-seepage membrane 8 is located on the bottom and the hypotenuse of the designed section, and its main function is to prevent sewage from seeping down and polluting groundwater.
[0025] The pretreated sewage passes through the water inlet pip...
