The mode of sewage recovery has certain defects that firstly, rainwater and sewage cannot be split, particularly when the rainwater and the sewage enter a sewage treatment station together, so that the storage space of a sewage pool is occupied, and the treatment burden of the sewage station is increased; and when the rainfall is large, the storage capacity of the polluted water station is affected, so that the sewage pool overflows into a catch basin, and environmental pollution is caused. The existing rain and sewage diversion system is mainly used for urban buildings and is rarely proposed in the chemical industry field.

By adopting three sets of drainage pipelines of rain, sewage and waste, the sewage is strictly classified according to water quality, the septic tank effluent of the building unit enters an independent sewage pipe and is not communicated with a domestic waste water pipeline, so that the problem that the odor of the septic tank flows backward into a room is effectively solved.
CN112962753a discloses a rain and sewage diversion system, which comprises a ground matrix, a diversion discharge assembly arranged in the ground matrix and a rain water collection assembly connected above the diversion discharge assembly, wherein a plurality of groups of rain water collection assemblies are distributed on the top surface of the ground matrix, and the lower end of the rain water collection assembly penetrates through the ground matrix and is communicated with the diversion discharge assembly. The rain and sewage diversion system effectively protects and prevents corrosion to the outer sleeve, prolongs the service life of the whole diversion pipe, improves the rainwater discharge quality, effectively removes surface impurities, and avoids blocking meshes.
