Which water quality is not conducive to the normal treatment of sewage treatment plants? How to solve it?

In today's highly developed industry, although people enjoy all kinds of happiness brought by industrial development, they also suffer from all kinds of misfortunes brought about by environmental damage. In order to increase people's happiness index, and for the country to In the long-term and healthy development, various countries have issued corresponding sewage treatment policies. In the process of industrial sewage treatment, it is necessary to fully understand and classify the types of sewage. In the process of sewage treatment, various sewage problems will be encountered.

For example COD, ammonia nitrogen, SS, and other indicators are not up to standard, sludge bulking, floating sludge and the death of active microorganisms, etc. However, many sewage treatment plants in my country's cities have been built for many years and still cannot operate at full capacity, which makes the control of the sewage treatment process more difficult, and also increases the cost of project investment, resulting in idle and waste of assets. Efficient use of pollution control funds and maximizing the rate of sewage collection are the prerequisites for realizing sewage emission reduction.

Which water quality is not conducive to the normal operation of the sewage treatment plant?

1. The content of BOD and COD in the influent water is lower than the design value, while the indicators such as nitrogen and phosphorus are equal to or higher than the design value, which increases the difficulty of the sewage denitrification and phosphorus removal treatment to meet the discharge standards;

2. The entrained oil or toxic substances in industrial wastewater have a huge impact on the biological system of urban sewage treatment plants. In extreme cases, these oil or toxic substances will paralyze the entire biological system, microbial strains will die, and the entire sewage treatment will The plant had to re-cultivate activated sludge;

3. The quality of influent water is high, and the specifications of oxygen supply and sludge dewatering equipment cannot meet the requirements of sewage and sludge treatment. Among them, the impact of the introduction of landfill leachate on the operation of urban sewage treatment plants needs to be paid enough attention to.

How to solve this situation?

In order to protect the environment, in the process of industrial sewage treatment, it is necessary to fully understand and analyze the type of sewage. At this time, a professional sewage water quality detector is essential.
