What are the precautions for selecting integrated sewage treatment equipment processes?

  1、 Wastewater quality. The quality of domestic sewage is usually relatively stable, and general treatment methods include acidification, aerobic biological treatment, disinfection, etc. The reasonable selection of process flow for industrial wastewater should be based on specific water quality conditions. It should be noted that when using aerobic biological treatment technology to treat wastewater, attention should be paid to the biodegradability of the wastewater. Anaerobic biological hydrolysis acidification can also be carried out to improve the biodegradability of wastewater, or non biological physical or chemical methods can be considered for treatment.
2、 Construction and operation costs. When considering construction and operation costs, it should be a prerequisite for treating water to meet water quality standards. Under this premise, the low cost process of engineering construction and operation should be given due attention. In addition, reducing the footprint is also an important measure to lower construction costs
3、 The degree of sewage treatment. The quality of domestic sewage is usually relatively stable, and general treatment methods include acidification, aerobic biological treatment, disinfection, etc. The reasonable selection of process flow for industrial wastewater should be based on specific water quality conditions. It should be pointed out that when using aerobic biological treatment technology to treat wastewater, attention should be paid to the biodegradability of the wastewater, and anaerobic biological hydrolysis acidification should also be considered to improve the biodegradability of the wastewater, or non biological physical or chemical methods should be considered.
4、 The difficulty level of engineering construction. The difficulty level of engineering construction is also one of the influencing factors in choosing the process flow. If the groundwater level is high and the geological conditions are poor, it is not suitable to use deep and difficult to construct treatment structures.
5、 The amount of sewage. In addition to water quality, the amount of sewage is also one of the influencing factors. For sewage with large changes in water quantity and quality, the first consideration should be to adopt processes with strong shock load resistance, or to consider setting up buffering equipment such as regulating tanks to minimize adverse effects.
6、 The local natural and social conditions. The local terrain, climate, and other natural conditions also have a certain impact on the selection of wastewater treatment processes. Local social conditions such as raw materials, water resources, and electricity supply are also factors that should be considered in process selection.
7、 Does the handling process generate new conflicts. During the sewage treatment process, attention should be paid to whether it will cause secondary pollution problems.
