After water of ordinary all corners of the country is sending waterworks, want to be handled through chloridize, chloric the organic matter with the remain in water interaction, can form the poisonous compound causing cancer such as bittern acting hydrocarbon, chloroform. Study a proof, closely related lukewarm change of content of bittern acting hydrocarbon, chloroform and water and boiling duration accident. Arrive when water temperature rise 100 ℃ , the content of bittern acting hydrocarbon and chloroform is mixed for 110 microgramme respectively 99 microgramme, exceed national level. If continue to boil, after lasting 3 minutes, bittern acting hydrocarbon and chloroform content fall to be mixed to 9.2 microgramme respectively 8.3 microgramme, just become safe drinking water right now.
