Detailed ways

As shown in Figure 1, the practical sewage treatment system includes an oil separation sedimentation tank, a rainwater collection device, a biofilm processor, a vortex separator 20 and a fire-fighting water storage tank; an oil separation sedimentation tank, a biofilm processor, and a vortex separator 20 It is connected to the fire storage tank in turn through pipelines; the rainwater collection device is connected to the biofilm processor through pipelines. The utility model processes and reuses domestic sewage, sewage generated by the system and rainwater, improves the utilization efficiency of water resources, and realizes the recycling of water resources.

The working process of this utility is as follows:

As shown in Figure 2, the domestic sewage enters the oil separation sedimentation tank through the sewage water inlet 1, and the coarse and fine screens (2, 3) intercept the solid waste in the sewage, remove some large suspended solids in the sewage, and settle in the sludge Slope 4 sedimentation, the turbulent flow of sewage in the oil-separating sedimentation tank can make the floating matter in the sewage such as floating oil float to the liquid surface, and then be removed through the floating matter removal port 5, and the lower sludge discharge port 7 is passed through the sludge pump The role of the sludge can be quickly discharged from the system. After flowing through the oil-separating sedimentation tank, the sewage is initially purified and flows into the biofilm processor through the outlet 6 of the oil-separating sedimentation tank through the pipeline.

As shown in Figure 3, water flows in through the biofilm processor water inlet 8 of the biofilm processor. After the water passes through the front flap 10, the suspended solids are removed through the scum removal port 9. After that, the water passes through the overflow weir 11, and then passes through the After the aeration pipe 12 is aerated, it passes through the biofilm and the packing layer 13, and the effluent flows into the vortex separator 20 through the outlet 14 of the biofilm processor. The mud is discharged from the system, and the separated effluent enters the water inlet 15 of the fire storage tank.

As shown in Figure 4, the wall of the fire storage pool is coated with a photocatalytic coating 19, and an ultraviolet lamp 18 is arranged in the pool to irradiate to carry out double disinfection, sterilization and deodorization measures of ultraviolet rays and photocatalysis, and the overflow port 17 on the upper part can control the water level at a specified limit Inside, the fire-fighting water suction pipe is connected with the water pump, and the water in the storage tank is extracted out by the fire-fighting water suction port 16, and is delivered to the pipelines for car washing, toilet flushing, greening and fire-fighting water respectively.

This practical sewage treatment system occupies less land and requires less investment, and can be applied to small-scale areas such as residential areas and schools to meet the sewage treatment needs of areas such as residential areas and schools; the system is simple and efficient, and can reduce the amount of existing urban sewage. The burden of the treatment plant; the utilization efficiency of water resources is improved, the recycling of water resources is realized, and the treated sewage can be used as water for car washing, toilet flushing, greening and fire protection, which is very economical and environmentally friendly.
