On October 5, parking for maintenance purposes led to water being discharged from the electrolysis unit into the sewage tank, causing the pH level in the sewage tank to rise significantly above the allowed limits – a fine of 50 yuan. What’s your opinion on this issue?
This problem is too complex to explain. Let’s see who will be held accountable? Operator? Class leader? Shop supervisor? Who agrees to the drainage (the person in charge).
Can the water used for washing the cell after it has been shut down be avoided from being discharged? Isn’t a sewage tank just a place for treating wastewater?
There is a lot of pressure to protect the environment these days; we focus on managing things at the source, and those who discharge pollutants illegally are subject to fines. Since the treatment capacity of the sewage treatment plant is limited, your situation is probably also a matter of necessity.
It was always arranged this way before, and then suddenly there were penalties imposed without even any chance for correction. If the water used for cleaning the electrolyzer cell isn’t drained, can it still be left inside the electrolyzer?
It is a matter of rules and regulations. To discharge abnormal wastewater, it is necessary to first file a declaration, contact the wastewater treatment plant, and discharge it in batches according to a plan (so as not to overwhelm the plant’s processing capacity or limits), while also going through the procedures for transferring such wastewater.
Whether to arrange it or not and how to arrange it are two different concepts! ! !
The water must definitely be drained, but communication is required – one needs to contact the dispatch team and the wastewater treatment department, and only after receiving a positive response can the drainage take place.
First, carry out neutralization to lower the pH value before proceeding with the treatment.
If the water in the washing tank contains few impurities, it can be reused for desalination; the water can be recycled and less alkali can be used
