Drainage health without ignores
At present, the residential sewage pipes in our country also have serious health risks. According to the investigation by the Shanghai Center for Disease Control and Prevention, household sewers contain a large number of germs of various types, which may cause diarrhea, food poisoning, pneumonia and other diseases. In addition, cockroaches, mosquitoes, butterfly flies and other pests can inhabit the sewer, further spreading the spread of germs. Odors from the drainage system mainly include hydrogen sulfide, methane, ammonia and nitrogen. In addition to producing foul odors, these gases can also cause damage to the human respiratory tract and lungs.
