Problems solved by technology

Most of the disinfection of tap water now adopts the chlorination method. The main purpose of chlorination of public water supply is to prevent water-borne diseases. This method has been promoted for more than 100 years. It has relatively complete production technology and equipment. The effect is good and the cost is low, but there are still some disadvantages when chlorine gas is used for tap water disinfection. Chlorine interacts with residual organic matter in water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform, and the tap water obtained by disinfection has an unpleasant smell

Embodiment 1

[0013] Embodiment 1, a kind of tap water disinfection method comprises the following steps,

[0014] (1) Crush stamens to 100 meshes, mix them evenly with tap water to be treated and amylose in a weight ratio of 5:1000:1, and introduce krypton gas into the tap water at a rate of 5 per cubic meter of tap water. Inject helium at a rate of -8ml / s for 10 minutes;

[0015] (2) Inoculate tap water with amylase at a ratio of 2%, adjust the pH to 5.2, stir and react at a stirring rate of 180r / min at 30°C for 1 hour, dissolve vitamin B6 in tap water at a ratio of 3‰, and again Stirring and reacting for 2 hours with a stirring rate of 180r / min;

[0016] (3) Send the treated tap water into the clarification tank for clarification. The pressure in the clarification chamber is 30MPa, and the clarification is maintained for 3 hours to obtain sterilized tap water.

Embodiment 2

[0017] Embodiment 2, a kind of tap water disinfection method comprises the following steps,

[0018] (1) Grind stamens to 120 mesh, mix them with tap water to be treated and amylose in a weight ratio of 8:1000:1.5, and inject krypton gas into the tap water at a rate of 8ml per cubic meter of tap water. Inject helium at a rate of / s for 12 minutes;

[0019] (2) Inoculate tap water with amylase at a ratio of 2%, adjust the pH to 5.5, stir and react at a stirring rate of 200r / min at 35°C for 2 hours, dissolve vitamin B6 in tap water at a ratio of 3‰, and again Stirring and reacting at a stirring rate of 200r / min for 3 hours;

[0020] (3) Send the treated tap water into the clarification tank for clarification. The pressure in the clarification chamber is 35MPa, and the clarification is maintained for 4 hours to obtain sterilized tap water.

Embodiment 3

[0021] Embodiment 3, a kind of tap water disinfection method comprises the following steps,

[0022] (1) Crush stamens to 110 meshes, mix them with tap water to be treated and amylose in a weight ratio of 7:1000:1.3, and inject krypton gas into the tap water at a rate of 7ml per cubic meter of tap water. Inject helium at a rate of / s for 11 minutes;

[0023] (2) Inoculate tap water with amylase at a ratio of 2%, adjust the pH to 5.3, stir and react at 32°C at a stirring rate of 190r / min for 1.5 hours, dissolve vitamin B6 in tap water at a ratio of 3‰, and again Stir the reaction with a stirring rate of 190r / min for 2.2 hours;

[0024] (3) Send the treated tap water into the clarification tank for clarification. The pressure in the clarification chamber is 32MPa, and the clarification is maintained for 3.3 hours to obtain sterilized tap water.

Abstract

The invention relates to the field of drinking water disinfection, in particular to a tap water disinfection method. The method includes the specific steps that Ophicalcitum is smashed and evenly mixed with tap water to be treated and amylose, krypton is introduced into the tap water for sterilization, the tap water is inoculated with amylase in the proportion of 2% for preliminary enzymolysis, the treated tap water is fed into a clarification tank for clarification, pressure-maintaining clarification is conducted for 3-4 hours with the pressure in a clarification room being 30-35 MPa, and finally the disinfected tap water is obtained. The tap water disinfection method is very simple; substances harmful to the human body are not generated in the disinfection process, in other words, secondary pollution to water is avoided; common viruses (rotavirus, the hepatitis virus, enterovirus and the like) in water can be efficiently and thoroughly killed.

Description

technical field [0001] The invention relates to the field of drinking water disinfection, in particular to a tap water disinfection method. Background technique [0002] Tap water refers to the water that is purified and disinfected by tap water treatment plants and meets the corresponding standards for people's living and production use. People in the city drink tap water, and ordinary river and lake water is chlorinated after being sent to the waterworks to remove impurities such as microorganisms. Most of the disinfection of tap water now adopts the chlorination method. The main purpose of chlorination of public water supply is to prevent water-borne diseases. This method has been promoted for more than 100 years. It has relatively complete production technology and equipment. The effect is good and the cost is low, but there are still some disadvantages when chlorine gas is used for tap water disinfection.
