Problems faced by sewage treatment

As the equipment optimization stage, the electronic scale removal instrument can prevent the formation of carbonate scale, and can effectively kill bacteria and algae, rust and corrosion prevention, but also has a good scale removal effect, to ensure that the equipment with the lowest power consumption continuous operation;

Living water:

Domestic sewage treatment

Domestic sewage treatment equipment is mainly used for the purification of domestic sewage in hotels, restaurants, schools, organs and factories, so that the treated sewage can meet the discharge standards stipulated by the state.

Process features:

1, the use of water acidification and biological contact oxidation combined method, effectively improve the treatment effect, completely up to the standard discharge.

2, the amount of sludge generated is small, the sludge generated at each stage can be reflux digestion, and the final sludge is regularly extracted.

3, the equipment can be organically combined, located under the surface or in the basement, can also be buried. When buried in the ground, the top of the equipment can be used as a parking lot or green lawn, in harmony with the surrounding environment.

4, high degree of equipment automation, reduce the workload of operation.

5, low noise, no odor, no impact on the surrounding environment.

Boiler water:

Processing characteristics

Boiler water treatment does not require complex equipment, so the investment is small, the cost is low, and the operation is convenient.

Boiler dosing treatment is the most basic water treatment method, and it is also the continuation and supplement of chemical water treatment outside the pot. After the external water treatment may also have residual hardness, in order to prevent boiler scaling and corrosion, still add a certain water treatment agent.

Boiler water treatment can not completely prevent boiler scaling, especially the generated dirt scale, which is easy to form secondary scale when the sewage is not timely.

Boiler dosing treatment method has no pollution to the environment, it is not like ion exchange and other water treatment methods, how many impurities are treated in natural water, how many impurities are discharged after regeneration, and also discharge a large number of remaining regenerants and regenerated products. The boiler dosing treatment method is to turn the main impurities in the water into insoluble dirt, which will not cause pollution to nature.

The formula used in the boiler dosing method needs to match the feed water quality. When the feed water hardness is too high, a large amount of water slag will be formed and the scaling speed of the heat transfer surface will be accelerated. Therefore, it is generally not suitable for high hardness water.

Analysis of problems:

1, water treatment technology is not advanced enough

China's water treatment technology is backward, in addition to the slow development of reasons, there is a certain gap between the level of science and technology and advanced countries, and the effective use of water resources is not as good as developed countries. For example, in the 1990s, China's industrial water recycling rate was only about 40 percent, only equivalent to the level of the United States in the early 1970s. Moreover, China's sewage treatment rate is below 40 percent. Backward water treatment technology makes our country unable to effectively use the limited water resources, resulting in a lot of waste.

2. Serious water pollution

According to the investigation, nearly 80 percent of China's rivers have been polluted to varying degrees, and the vast majority of rivers flowing through China's large and medium-sized cities are polluted, and nearly 80 percent are seriously polluted. What's more, the groundwater pollution in most large and medium-sized cities of our country is also very serious. With the improper use of pesticides, the source of some rivers is polluted, which in turn causes the entire river to escape, causing pollution from the point to the surface, from the main stream to the tributaries in a spider web.

3, the lack of water treatment technical personnel

Water treatment has become an issue of global attention, however, China has not set up relevant majors to train professional water treatment technical personnel. The reason is that water treatment technology involves too many disciplines and fields, such as chemistry, physics, biology, environment and so on. Moreover, water treatment technology needs to be combined with practice and dependent on high-tech science and technology, so it is difficult to clearly give basic theories, and it is difficult to teach and improve students' cognition.

The prospect of water treatment technology in China

As environmental problems become more and more serious, environmental protection has gradually entered the country's vision. At the same time, a lot of water treatment technology has also been made great progress, in general, that is high efficiency, simple and convenient, low energy consumption.

1. Adhere to the path of sustainable development

While it is important to protect the environment, we should not put the economy on hold and hinder its development. In order to coordinate the relationship between the two, government departments can actively encourage enterprises to raise funds, and vigorously build sewage treatment plants and increase the intensity of sewage purification while ensuring economic development.
