What methods are used to solve clogged sewer drains?

1. Use another well for wastewater discharge. 2. The first option cannot be used; only cleaning is possible. The internal contents can be removed using a sludge pumping pump, or by clearing it with bamboo strips. Because bamboo blanks have a certain degree of flexibility and are not easy to break. But there’s a convenient way: a clog remover! This thing is quite useful! It’s just that this kind of equipment is usually only available in property management companies, and it’s used to clear drains in residents’ homes; it seems that chemical plants don’t have such equipment.

First, determine what is blocking the passage. If it is an oil with high viscosity, such as crude oil, steam heating can be used, by increasing the number of steam supply points.

As mentioned on the second floor, first determine what is causing the blockage. If it’s oil or naphthalene, use steam to clear it; while doing so, make sure to insert a pipe into the tube at regular intervals. With patience, the blockage can definitely be removed. In our factory, there was a 50-meter-long blockage. During desulfurization, large amounts of wastewater flowed into the drainage pipes, causing backflow all the way to the ammonium sulfate production area. The supervisor in charge of desulfurization reported to the workshop, saying, “The drains are blocked – the blockage is so severe that nothing can get through it.” It’s true that once naphthalene and tar block it, it can’t be pried open. Just as the workshop supervisor was about to inform the engineering department to dig the sewer again, the supervisor in charge of ammonium sulfate came over and said, “It won’t take long to clear it out once steam is applied.” The benzene workshop supervisor said, “It’s completely impossible.” Later, because of this, the two foremen started arguing in front of the workshop supervisor. Eventually, they made a bet: once the task was completed, the foreman in charge of crude benzene would give 300 yuan to the foreman in charge of ammonium sulfate. If the sulfur ammonium cannot be blown through, the foreman will also give 150 yuan to the crude benzene foreman. The workshop supervisor was of course the happiest at this point, as having someone to do the work was a good thing anyway. Later, the ammonium sulfate supervisor found someone in the workshop and told him how to do it; he didn’t do it himself. Indeed, it took just one day to clear all the more than 50 meters of pipelines. The ammonium sulfate supervisor received 300 yuan from the manager; he gave 200 yuan to those who were doing the work, and kept the remaining 100 yuan to treat us, who were there, to a meal. It’s interesting to think about it. Later, I heard from the supervisor in charge of ammonium sulfide that it was naphthalene and tar that blocked the sewers; at a certain temperature, they would melt away quickly. He knew there would be no problem, which is why he dared to take that gamble. What remarkable skill and boldness.

Generally, mud, oil residues, and the like can be blown away with steam; if that doesn’t work, blowing in the opposite direction can help, and it’s best to do it under pressure.

Different devices are not the same; we once blocked it and cleared it out using rebar, but later we still carried out technical upgrades and replaced the sewer pipes

Using a high-pressure water cannon vehicle designed for cleaning underground pipes, the problem can be solved easily.
