During the operation and maintenance of integrated sewage equipment, there are many reasons why water quality cannot meet standards. The following will introduce countermeasures based on specific problems.

       1. Low temperatures in winter lead to inactivation of bacteria

       If the temperature is too low in winter, it will seriously affect the growth and metabolism of microorganisms and the sewage purification effect. If the equipment does not adopt an underground design or heating components, insulation measures for the integrated sewage equipment need to be taken in advance.

       2. Incoming water is mixed with industrial wastewater, causing microbial poisoning

  

       3. The carbon-nitrogen ratio of the incoming water is unbalanced

  

       Integrated sewage equipment has many parameters that can be adjusted. For example, the operating parameters of the fan will affect the amount of dissolved oxygen, thereby changing the activity of aerobic microorganisms, and the sludge return will affect the nitrification and denitrification effects. Therefore, combined with water quality laboratory analysis, optimizing equipment operating parameters is one of the important means to improve water quality.
