Why the septic tanks are congested in rural suppliers is a problem of great concern to the relevant departments. The phenomenon of septic tank clogging, including the fact that the waste food and leftovers are blocking the toilets, and many septic tanks in old areas are more likely to be blocked. Around the Spring Festival, there are especially many septic tanks in communities every year, which makes us very headache.
In fact, at the beginning of each year, it is a busy time for the business department of the municipal environmental sanitation department. Because "in this period of time, the water in the septic tank is more concentrated." The key areas where septic tanks block and overflow frequently are mainly some open residential areas and old buildings in old urban areas. There are also septic tanks with corrosion and other problems due to long use time. At present, plastic septic tanks are widely used. Plastic septic tanks have strong corrosion resistance and other characteristics, so they are relatively practical materials at present.
So what are the main aspects of septic tank overflow?
Some of these problems are related to the design of urban septic tanks. In addition, due to the aging of the facilities, the annual sewage discharge has increased, resulting in this situation.
The second is the blockage caused by oil, which is even worse. Some residents think the toilet drain is thick and like to pour leftovers into the toilet. Along the street, some restaurants also use waste oil septic tanks. The accumulated septic tank oil layer accumulated for a long time, coupled with low temperature at the beginning of this year, is easy to coagulate.
What's more, garbage blocks the septic tank. Every time you clean the septic tank, you will see a large number of sanitary napkins, plastic bags, even brushes, chopsticks, coke bottles, which are not like feces after septic tank sedimentation, fermentation can be discharged, they sink in the septic tank, easy to cause blockage.
It's up to everyone to keep the septic tank. If everyone doesn't realize it, it's too late to complain about the problem.
