Kitchen sewage is mainly leftovers, detergents, etc., these are non-toxic substances, a small amount of water into the pond can be quickly decomposed, but too much can cause eutrophication.
Be hygienic and clean.

There is sewage flowing out of the ceiling of the building, most likely due to the iron pipes used in the old house, and the leakage of the upper and lower sewer pipes on the upper and lower floors. It is best to disassemble the ceiling of the kitchen to see, you should be able to see that there is a leakage, just replace it with a section of PVC pipe.
Domestic pollutants belong to pollution, air pollution, and environmental pollution.
Of course, that's not good, it affects the environment, you talk to your uncle and ask him to pay attention not to do this.
The sealing ring butted between the toilet drain and the toilet drain is misaligned or poorly sealed, resulting in sewage overflowing through the gaps. If the toilet is not fixed with expansion screws, scrape off the sealant that is in contact with the brick surface of the toilet, lift the toilet, re-dock, and re-apply the sealant after placing the toilet.
