Study On The Rule And Mechanism Of The Quality Change Of Drinkable Water

In order to the settle the long-term argument over drinking water, to save water resources, to protect ecological environment and improve the living standards and health standards of the Chinese people, the present paper attempts to make a research and analysis on the quality and testing data of the purified water produced by means of different techniques in the large market. The paper also makes a comparative analysis on the ability of different methods to destroy harmful microorganisms in the tap water, the durability, by-products and toxicants as well as the cost and benefits. Besides this, the paper tries to make a testing analysis on the quality of tap water purified at different heating temperature and boiling time with liquid chlorine and then makes a further study on it. As a result of this, a conclusion is reached about the better type of drinkable water and better drinking way so that a reliable theory is put forward here to improve the providing way of water for the inhabitants in the city and to set up a more scientific idea about drinkable water.
