In tower operations, a table for adjusting operating parameters is usually established; for example, the feed rate, feed composition, and feed temperature are related to parameters such as the bottom temperature of the tower, tower pressure, and reflux rate. The appropriate auxiliary parameters are selected based on changes in the feed. Is it then necessary to establish a table of operating parameters to control the operating conditions during wastewater treatment? For example, what should be the ranges for dissolved oxygen, recirculation rate, and SV30 at water temperatures of 15–20°C, 20–30°C, and above 30°C, rather than making adjustments on a ad-hoc basis depending on the actual operating conditions? ； With this table, there will be fixed operating conditions to serve as a basis for operation, which will greatly assist in the stable operation of the wastewater treatment system. Let’s all discuss whether it’s necessary to create this table and how to do it
Personally, I think creating a parameter comparison table makes it easier to make adjustments. Creating a table is a bit troublesome due to too many parameters and numerous variations. I can’t think of a good solution.
If this table is created, can the operators use it to adjust their operations? It’s possible to determine the appropriate operating conditions for spring, autumn, winter, and summer, and then follow those guidelines – just like in the operating procedures for centrifugal pumps. That’s extremely convenient!
Wastewater represents dynamic operating conditions, and the levels of uncertainty and variability differ from those in chemical production processes; moreover, the degree of interaction between these factors is quite high. For example, F/M is related to SV30, MLSS, as well as DO, water temperature, residence time, recirculation rate, and the composition of wastewater pollutants. It is difficult to create a universal table for this purpose, and significant effort would be required even if such a table were to be developed.
For operational management, it is still necessary; with more data, it becomes easier to identify patterns
A table should be created to guide everyone in pre-mixing and preventing accidents, etc
I don’t understand this, but it’s still good for my knowledge
It is necessary to create an operation control table for this purpose. 1. It is possible to monitor the operating status of each processing unit in real time ； 2. Problems can be identified in a timely manner, provided that the operation records are accurate and valid ； 3. Be able to identify the cause of the problem as soon as possible ； 4. Through extensive operational data, energy conservation and consumption reduction can be achieved, thereby lowering operating costs. This is my personal opinion for reference only.
A framework parameter table should be established based on the data accumulated from operational experience, along with the conclusions of qualitative analysis.
If it can be established, that would definitely be great! The key issue is that the data changes might be too significant, so it can’t be handled like in a tank area! The most important thing is that I don’t understand anything about sewage either :'(
Create a comparison table of operating parameters. This table can basically determine the range once debugging is completed. Then, the inspectors monitor the parameters of each unit. If there are significant fluctuations, corresponding adjustments need to be made. All of these should be included in the operating procedures.
