mention Sewage environmental protection equipment It's a little heavy. For sewage treatment, entrepreneurs and businessmen are not willing to use this equipment. After all, the cost and later operation need capital support, and they are not willing to pay for it. With the improvement of the people's and the country's awareness of the environment, entrepreneurs have been on the sewage treatment equipment. The corresponding solutions for different products will also be given in the corresponding solutions.

Let's first look at the definition of the national sewage discharge standard:

Sewage: wastewater discharge standard clearly indicates that sewage is the general term of water discharged from living activities and production activities.

Discharge: in short, it is directly used in the production process, but should not include power station drainage, indirect cooling water and plant boilers.

All drains: simply put, drains are suitable for use in this range.

Other drainage units: refers to the drainage units other than a certain project. The technical contents of the comprehensive wastewater discharge standard are as follows:

The first level standard: the secondary water discharged to gb3097 and the sewage discharged to gb3838iii need to implement first-class standards in addition to the protected areas and swimming areas.

Secondary standard: the three kinds of water discharged in gb3097z and the IV / V sewage in gb3838 are required to implement the secondary standard.

Class III standard: if the wastewater from the domestic sewage system discharged from the secondary sewage treatment plant needs the third level standard. Understanding the key elements of comprehensive wastewater discharge standards can effectively understand the national wastewater discharge standards to meet the specified discharge requirements.

The following aspects should be taken into consideration when purchasing sewage environmental protection treatment equipment:

1. Wastewater quality

The quality of domestic sewage is usually stable, and the general treatment methods include acidification, aerobic biological treatment, disinfection, etc. Industrial wastewater should be reasonably selected according to the specific water quality. In particular, for the treatment of wastewater by aerobic biological treatment process, attention should be paid to the biodegradability of wastewater, which usually requires COD / BOD5 > 0.3. If the requirements cannot be met, anaerobic biological hydrolysis acidification can be considered to improve the biodegradability of wastewater, or non biological physical or chemical treatment methods should be considered

2 sewage treatment degree

This is the main basis for the selection of wastewater treatment process. In principle, the degree of sewage treatment depends on the water quality characteristics, the direction of the treated water and the self purification capacity of the water body. However, at present, the determination of the degree of sewage treatment mainly follows the requirements of the relevant national legal system and technical policies. Generally, environmental management departments control the discharge concentration of sewage according to the integrated wastewater discharge standard and relevant industrial discharge standards. Some areas with higher economic development level also have more stringent local discharge standards. Therefore, no matter what kind of sewage needs to be treated, and no matter what kind of treatment process and treatment degree is adopted, it should be based on the premise that the effluent of the treatment system can reach the standard. According to the requirements of laws, regulations and policies, water environmental pollution shall be prevented and controlled.

3 construction and operation costs

When considering the construction and operation costs, the precondition should be that the treated water meets the water quality standard. On this premise, the process flow with low construction and operation cost should be paid attention to. In addition, reducing land occupation is also an important measure to reduce construction costs

4. Construction difficulty

The difficulty of engineering construction is also one of the influencing factors of process selection. If the groundwater level is high and the geological conditions are poor, it is not suitable to select the treatment structures with large depth and high construction difficulty.

5. Local natural and social conditions

Local topography, climate and other natural conditions also have a certain impact on the selection of wastewater treatment process. If the local climate is cold, the process that can operate normally in low temperature season and ensure the water quality to reach the standard should be adopted. Local social conditions such as raw materials, water resources and power supply are also one of the factors that should be considered in process selection.

6 quantity of sewage

In addition to water quality, the amount of sewage is also one of the influencing factors. For the wastewater with large changes in water quantity and quality, the process with strong anti shock load capacity should be considered first, or the buffer facilities such as regulating pool should be set up to minimize the adverse impact.

Is there any new contradiction in the process

In the process of sewage treatment, attention should be paid to whether secondary pollution will be caused.
