Problems faced by sewage treatment

2. Build an environmentally friendly and efficient sewage treatment plant

Perhaps many people do not know that sewage treatment plants also produce waste gas and sludge. If we ignore it, it will cause secondary pollution. Therefore, we can take certain treatment methods to remove the exhaust gas. For example, we can purify the exhaust gas produced by treating sewage by means of deodorizing burners. Perhaps wait three or five years, or ten years later, when the environmental protection technology becomes mature, the treatment method of waste gas sludge is more scientific and reasonable, so that the sewage treatment plant becomes the number one role in eliminating pollution!

In the construction of sewage treatment plants, we can not but consider the cost, can not not consider the speed of resource consumption. Therefore, we should also vigorously develop water treatment technology, hoping to research low energy consumption, high efficiency treatment technology. This will not only reduce costs, but also improve the water quality, thereby improving the environment in which we live.

3. Change the operation mechanism of sewage treatment plants

Although the construction of sewage treatment plants is inseparable from improving the water resources environment, if the factory is always allowed to operate regardless of the cost, it is estimated that no one is willing to. Therefore, if we transform the institutional mechanism of sewage treatment plants into a business model, so that they can also have certain economic benefits, will the treatment effect of sewage treatment plants be improved? Because once converted to a business model, sewage treatment plants will certainly find ways to improve their sewage treatment methods and improve water quality. In this way, they will be stimulated to actively participate in the improvement of water treatment research, and actively promote the improvement of water treatment technology.

4. Improve the reuse rate of recycled water

Sewage treatment does not have to meet the requirements of drinking, because some production water standards are not so high. Therefore, when the sewage has been treated, it can be used if it can meet some use requirements, and there is no need to purify it. This can not only realize sewage reuse, but also save treatment costs and improve water treatment efficiency. With the continuous updating of science and technology, the technology of sewage treatment will surely be more mature, and the scope of application will be broader, and it may be applied to many aspects such as agriculture, industry, and life.

5, proper disposal of sludge

After sewage treatment, a certain amount of sludge is often produced. Some of this sludge may contain toxins such as heavy metals, but it is not without merit. As long as we analyze the components of the sludge, we can naturally find a proper treatment method, so that they also have the value of use, to achieve the purpose of effective use and resource conservation.
