What factors need to be considered in wastewater treatment

 1、 Wastewater quality

When it comes to Sewage Treatment, it is recommended that we consider the quality of wastewater in daily life based on the actual situation, because the water quality of domestic sewage is usually relatively stable. The general treatment methods include acidification or oxidation biological methods, and disinfection methods can also be used for treatment. Industrial wastewater is basically treated based on the existing water quality situation to make reasonable choices in the process flow. Generally, we need to use various biological treatment processes for effective treatment, and pay attention to the biodegradability of each Wastewater treatment, which is usually required to be controlled at 0.3 or above. If it cannot meet the requirements, anaerobic biological water acid digestion can be considered to improve the biodegradability of wastewater, Non biological physical or chemical treatment methods can also be considered.

2、 Degree of sewage treatment

When treating industrial wastewater, the wastewater treatment process should be considered in conjunction with the existing technology. The degree of wastewater treatment mainly depends on the water quality characteristics of the wastewater, the flow direction of the treated water, and the financial capacity of the wastewater treatment plant itself. However, from the current situation, the degree of wastewater treatment is mainly directly related to the national laws and regulations, which means it must rely on existing policies. According to the current wastewater discharge standards, in order to achieve certain wastewater discharge standards, some places with relatively high economic development levels can still have standardized wastewater treatment standards, while places with poor economic development conditions are not very optimistic. Therefore, no matter where sewage treatment is required, no matter what process or degree of treatment is chosen, we must use a systematic approach to achieve effective treatment.
