How to eliminate the stench gas treatment of urban sewage sludge?Central Plains Environmental Protection R & D domestic leading deodorization system "breaks the problem"

Elephant News reporter Xia Ping

Slim stinky gases can be produced in urban sewage sludge treatment. Smelting can cause smell damage to the human body. It is one of the public harm that causes vomiting and causes disease.

On June 20, the reporter was informed that in response to the evil stinky gases generated during the treatment of sewage sludge, the Central Plains environmental protection continued to carry out technological innovation, technical research, and technical applications. The fundamental solution of Qi problem provides technical solutions.

As of now, the system has obtained 5 national practical new patents and 1 national computer software copyright. It has been identified as "leading domestic" through the evaluation of the scientific and technological achievements of the China Chuangchuang Science and Technology Evaluation Research Institute in Henan Province.

The reporter learned that during the processing of sewage treatment and sludge treatment, carbohydrates, protein, fat and other substances were easily used by anaerobic microorganisms for synthesis and decomposition, thereby forming a stench gase and divergent to the surrounding area. These evil odors are harmful to the health and ecological environment of the human body. At the same time, the odor is also corrosive after dissolving water, which is not conducive to the long -term safe and efficient operation of the sewage treatment plant equipment.

In order to maximize the impact of odor on the environment and ensure the efficient and stable operation of the sewage treatment plant, the Central Plains environmental protection and deep cultivation areas are deeply cultivated in the field of odor treatment. Provincial and municipal -level R & D platforms such as provincial sewage efficiency and low consumption treatment and sludge resource use engineering research centers "have continued to strengthen technological innovation.

Since the beginning of 2020, the Central Plains Environmental Protection R & D personnel have clearly established the needs of the front line from visiting and investigating first -line needs, and the analysis of the diversity of the flora, the full -component analysis of the odor, and then the installation design and construction. Exploration and innovation finally developed a set of replicable low -cost and efficient and precise biomedic deodorization systems. The biological fillers and deodorizing microorganisms in this system are independently developed by the Central Plains Environmental Protection. The filling performance is superior and long life. The microbial specificity is strong and the treatment effect is better.

According to the relevant person in charge of the Central Plains Environmental Protection, the system uses the equipment accurate deodorizing process, and the odor is easy to produce a gas hood, sealing or pipeline in the place where no person is required and the odor is easy to produce places. Select the equipment, reduce the air volume of the system, moderate investment, and simple management.

At present, this efficient and precise biomedic deodorization system has been promoted and applied to the commissioned operation project of the second sewage treatment plant in Zhengzhou Air Port Area and the commissioned operation projects of the sludge disposal of Jiyuan City. Social benefits and economic benefits. In addition, the system has also been carefully designed, rationally configured dust removal, condensate, spray and deodorization, which will be applied in places that need to be deodorized in garbage treatment, livestock and poultry breeding, food and drug processing.
