Cause of Hechi Sewer Explosion Accident

The cause of the Hechi sewer explosion accident may be caused by a variety of composite factors. The following are some possible reasons:

1. Aged and damaged sewer pipes: The Hechi sewer system was built earlier and the pipes Due to their long service life, sewer sewage pipes are aging and damaged, leading to pipe leaks and the production of harmful gases.

2. Failure to treat sewage in time: Pollutants in the sewer, such as organic waste, will decompose to produce harmful gases. If not treated in time, more and more harmful gases will accumulate, increasing the risk of explosions. .

3. Incomplete sewer cleaning: If sewer cleaning is not complete, residues and scale can gather with organic matter to create explosive conditions.

4. Rainwater and temperature: When rainwater flows into the sewer, the temperature difference between the hot air and the cold air may also cause an explosion. In addition, the accumulated water in the sewers will generate steam during hot weather. If it is not discharged in time, it will easily cause explosion conditions.

5. Human factors: As a public facility, sewers may cause explosion accidents if they are damaged or involve illegal dumping of garbage. For example, if hazardous materials such as toilet water and pesticides are accumulated in sewers, they may explode if they are accidentally collided or deliberately damaged.

In short, the cause of the Hechi sewer explosion accident may be a combination of multiple factors, including natural factors, human factors, aging facilities and other factors. It is necessary to strengthen the maintenance and management of facilities, eliminate hidden dangers in a timely manner, and ensure public safety. *Safety.
