Discarded plastic bottles have new uses

Japanese scientists recently invented a simple sewage treatment method. This method of treatment does not require special microorganisms and does not require expensive equipment. It is only possible to purify the waste water by using discarded lactic acid bacteria beverage plastic bottles.
The wastewater treatment technology invented by Professor Shi Kanxun of the University of Science and Technology of Japan is known as the "Ishii method." The working principle of the sewage treatment system using the "Ishii method" is very simple. The lactic acid bacteria beverage bottle at the bottom is about to be removed. The ground is filled up to form a filter tank, in which the sewage flows slowly, and then the air is filled into the water, so that a variety of microorganisms can survive and reproduce therein, and decompose the organic matter, thereby appearing a self-purification mechanism like a river. The sewage treated by the “Ishii’s way” sewage treatment system can be recycled.
According to reports, this simple sewage treatment technology has gained more and more attention in Japan. Household waste water and toilet excrement purification tanks produced using this technology are being popularized in Japan. Shi Jingxun was honored by the Japanese Ministry of Health, Science and Technology, and the Environment Agency for its invention.
The invention of this simple sewage treatment method has provided a new approach in sewage treatment technology, which not only avoids the waste of valuable water resources, but also saves a lot of sewage treatment costs. At the same time, it fully reuses the waste plastic bottles. Reducing plastic waste, protecting the environment and making contributions, with dual social and economic benefits (week)
