For pipeline purging, can sewage be discharged directly into rivers, lakes, and seas? No, which regulations apply (maritime regulations)? Yes, is that reasonable? What procedures need to be followed to do this. As far as I know, rust water can be declared for discharge, but I’m not sure if that’s correct
I’m not really sure; ask the local environmental protection authorities! Hehe, in our company, if we need to arrange special discharges, we have to submit a request in writing or by fax, and only after getting approval can we discharge waste
Go and check the environmental protection regulations; I think there are requirements in there.
Of course it shouldn’t be allowed; after parking, the pipelines contain oil residues or harmful substances, and such waste should be treated as oily wastewater
After parking, the pipelines should be purged; since different process materials have varying compositions, this can lead to certain levels of contamination, and such materials generally need to be treated before being discharged.
I was referring to the purging of pipelines that have not yet been put into use; my apologies, I wasn’t clear enough. This post was last edited by Mimi Mengmeng on 2008-1-15 23:20.]
It’s possible, but why must the water be discharged directly into rivers, lakes, and seas, rather than being treated first for use in landscaping or other purposes in order to conserve water resources?
You are absolutely right, but sometimes either the conditions or cost controls do not allow it to be done.
It depends on the substances present in the wastewater generated by your pipeline purging.
As for the purging water you mentioned, it can be discharged directly into rivers, lakes, and seas, but the key is whether the discharged water meets the emission standards set by environmental protection authorities, regardless of its source. Even the purging water for newly installed pipelines that have never been used may not meet the standards ； The purging water used for pipelines is not necessarily substandard either. There are too many factors here!
Is the pipeline purging water up to standard? How should it be handled? Which stage is responsible for this? For example, when I design pipelines, I don’t worry about where the purge gas goes; perhaps because we use nitrogen for purging, which is vented directly into the atmosphere, so there’s no risk of pollution. Is it then a matter for the factory and the construction company?
It would be best to explain the situation of your company to the environmental protection authorities and conduct a water quality test. If it’s a pipeline that isn’t in use, as you said, then the pollution levels in the wastewater discharged from it should be within acceptable limits. With permission from the environmental protection authorities, such wastewater can be discharged directly into third-class water bodies. However, under current environmental policies, I believe that ultimately the wastewater still needs to be routed through proper channels, as random discharge is not allowed. So it’s better to get in touch with the local wastewater treatment plant in advance to take over as soon as possible – that’s the long-term solution.
Your facility doesn’t have any water treatment equipment – how was the environmental impact assessment approved then?
