Family members, today we are going to talk about the key points of operating sewage treatment plants. They are all practical knowledge that can be gained from them, whether you are a novice or an experienced worker in this industry for many years!
Let's talk about water quality management first, it's of utmost importance! Our goal is to ensure that the effluent quality meets the standard. If the effluent does not meet the standard, all the previous efforts will be in vain. So it is necessary to establish a regular water quality monitoring mechanism, and key indicators such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen, and total phosphorus must be monitored and analyzed in real time. For example, it's like taking your body temperature every day to see if you have a fever. Once you find that the water quality is abnormal, like a sudden increase in body temperature, you need to take measures quickly, adjust the treatment process, find the cause, and not delay.
Let's talk about facility operation again. Wastewater treatment facilities are like various organs of our body that require regular inspection and maintenance to ensure normal operation. For example, the grille functions like a filter in our home, blocking large particles and impurities in the sewage. We need to check regularly for any blockages caused by slag. If there are blockages, it's like a clogged filter, which hinders the flow of water and prevents proper treatment of sewage. There is also a water pump, which is a key equipment for lifting sewage. Attention should be paid to checking the sealing condition and whether the impeller is damaged. If the sealing is not good, it is easy to leak water; If the impeller is broken, it will be impossible to lift the sewage smoothly. By the way, aeration equipment is also important as it provides oxygen to microorganisms, allowing them to better decompose pollutants in wastewater. If the aeration is uneven, with more oxygen in some areas and less oxygen in others, microorganisms will be unhappy and the treatment effect will naturally be affected. For equipment that has malfunctioned, it should be repaired as quickly as possible, just like putting out a fire, and not let it affect the entire processing flow.
The authenticity of online monitoring data must not be ignored. Nowadays, data speaks for itself, and online monitoring systems are like real-time recorders, recording various data during the sewage treatment process. But some people may use their brains to tamper with or falsify monitoring data, which is not acceptable! It's like cheating on an exam, and in the end, it's still harming oneself. We need to establish a sound management mechanism to ensure that these data are true and reliable, so that we can adjust our operational strategies based on the data. If the data is all fake, can the decisions made be correct?
Sludge treatment is also a major issue. Sludge is like the "garbage" generated during the sewage treatment process, which requires a standardized treatment process. Otherwise, it will be piled up everywhere, not only occupying space, but also polluting the environment and posing a threat to our health. Firstly, the sludge needs to be dehydrated to reduce its moisture content and transform it from a mud like state into a relatively dry mud cake. Then, based on the nature of the sludge, appropriate disposal methods can be selected, such as landfilling, incineration, or resource utilization, such as turning it into fertilizer. But no matter which method is used, we must strictly follow the regulations and not act recklessly.
Finally, let's talk about emergency plans. It's like buying insurance for a sewage treatment plant, no one knows when unexpected events may occur, such as sudden large-scale equipment failures, serious water quality exceeding standards, or natural disasters. At this point, if there is no emergency plan, one will be flustered and unsure of what to do. So it is necessary to develop detailed emergency plans in advance, and they cannot just be written on paper. Regular drills should also be conducted to ensure that every staff member understands what to do and how to respond in emergency situations. Only in this way can they respond quickly and effectively in case of emergencies, minimizing losses.
In short, each of these key points in the operation of sewage treatment plants is related to treatment efficiency, environmental safety, and economic benefits. Everyone must pay attention to them!
