1. Wastewater quality

In terms of sewage treatment, it is advocated to consider the water quality of domestic sewage based on actual conditions, as the overall water quality of domestic sewage is relatively stable. The general treatment methods include acidification or oxidation biological method, with optional usage for treatment. Industrial wastewater is generally based on existing water quality and requires multiple biological treatment processes for effective treatment, while paying attention to the biodegradability of each wastewater treatment. The general requirement is to control it above 0.3. If the requirements cannot be met, anaerobic biological acid digestion method can be considered to improve the biodegradability of wastewater, and physical or chemical non biological treatment methods can also be considered.

2. Degree of sewage treatment

When treating industrial wastewater, the sewage treatment process should be considered in conjunction with existing process conditions. The degree of sewage treatment mainly depends on the water quality characteristics of the sewage, the direction of the treated water flow, and the financial capacity of the sewage treatment plant itself. However, from the current situation, the degree of sewage treatment is primarily related to laws and regulations, which means it is necessary to rely on existing policies. According to the current sewage discharge standards, some economically developed areas can also have standardized sewage treatment standards in order to meet certain sewage discharge standards, while the situation in economically underdeveloped areas is not optimistic. Therefore, regardless of the local demand for sewage treatment, regardless of the chosen process or treatment level, it is necessary to carry out effective treatment through systematic methods.

3. Post construction cost

When selecting urban sewage treatment, if it contains industrial wastewater, construction or operation costs should be considered, and various water quality treatment conditions should be taken into account. Select appropriate water quality standards as treatment conditions. On this premise, the construction and operation costs of this project are relatively high, and the low process flow should be given more attention. In addition to effectively reducing land occupation, the related construction costs should also be reduced.

4. Engineering construction difficulty

In terms of sewage treatment, the construction difficulty of each project should be considered based on the actual situation. The difficulty of engineering construction can also affect the entire process, such as groundwater level or geological conditions. It is particularly inappropriate to select buildings that are large and difficult to construct. We are usually good and can learn from many aspects.

5. Local natural environment and social conditions

Regardless of the type of wastewater, the local natural or climatic conditions must be considered during the wastewater treatment process, which will have a direct impact on the treatment of wastewater. If the local climate is cold, fundamentally different technological conditions will be used for effective treatment, ensuring normal and effective operation during the low temperature season and ensuring existing water quality. When social conditions are available, it is necessary to consider these social conditions.
