Pouring Enzymes into Water, Xiushui Township Violates Water Pollution Act |彰化秀水鄉公所倒酵素清水溝 違反水汙法
Changhua Xiushui Township Office recently held an event to promote the use of enzyme powder inside drainage canal to eliminate odor. However, The Environmental Protection Bureau of Changhua County said that this has violated the Water Pollution Act, while scholars also said that the enzymes could make the water quality even worse.
People circled around the drainage ditch as they poured the dark liquid from bottles into the water. As this Fan-She drainage ditch has been emitting odors for many years, the Xiushui Township Office especially held this event in hopes that by using environmentally friendly and natural enzymes, the drainage ditch can be cleaned.
This drainage has been emitting horrible odors for the past ten-plus years. Locals and passersby all have negative feedbacks on it. As this kind of thing (enzymes) are purely organic, I think its pH will not impact the ecosystem of the drainage ditch.
However, the Environmental Protection Bureau of Changhua County said that this has violated the Water Pollution Control Act which stipulated that unauthorized substances may not be poured into the water. Scholars also said that pouring enzymes into the drainage ditch at will could make the water quality and odor even worse.
When substances that are not verified is added into the water, it calls for doubts with regards to the law. Enzymes are organic, and the drainage stinks mostly because there's an excess of nutrition in it. So when these enzymes are added into the water in large quantities without the proper mix of proportions, it may become anaerobic or impact the river's ability to clean itself.
Academically speaking, enzymes are quite specific. So you need to be clear of what you are trying to disintegrate and then try find the correct enzyme for it. If you just add a bunch of so-called enzymes, then you are probably just adding more nutrition (into the water), which will allow more microorganisms grow, and that will make the water stink even more.
Scholars said different enzymes have different functions, and not all enzymes can eliminate odors, so it's best to do some research on the enzymes before using them. The Bureau said that they will not penalize the township office, but it will ask all township offices to cease using this method to eliminate drainage ditch odors.
