Novel multifunctional sewage treatment system

[0038] as attached Figure 7 As shown, the bottom of the sealed box is provided with a water inlet pipe 17 for injecting sewage into the box, and one end of the water inlet pipe 17 is fixedly connected with a seepage pipe 18, and the seepage pipe 18 is laid on the bottom of the sealed box in a serpentine bend. At the bottom, the amount of laying of seepage pipe 18 at the bottom of the sealed box and the inflow of sewage have been increased.

[0040] as attached Figure 8-9 As shown, small holes 20 are drilled at intervals of 40cm-50cm on the seepage pipe 18, and sleeves 21 are arranged at the small holes 20 on the seepage pipe 18. The setting of the small holes 20 can effectively control the inflow of sewage, and the sleeve 21 The setting can prevent the sediment from flowing into the seepage pipe 18 with the sewage. After a long period of deposition, it will block the seepage pipe 18 and the small hole 20, affecting the inflow of sewage. The groove 22 and the setting of the diversion groove 22 can increase the inflow of sewage within the controllable range of the inflow of sewage.

[0042] Such as Figure 11 and 12 As shown, the lower part of the sealed box is provided with a deflector 29, and the deflector 29 divides the sealed box into a water inlet chamber 30 and a filter chamber 31 from bottom to top. The water inlet pipe; the filter chamber is laid with a variety of filter substrates, and the multi-layer filter substrate in the filter chamber is laid with large bluestone, small gravel, fine sand, modified zeolite, nanocomposite materials and soil layers in sequence from bottom to top; The top of the sealed box is provided with an outlet pipe 19 for draining and collecting the treated sewage water that has passed through various filter media from bottom to top; And the guide hole 32 of the filter chamber 31.
