specific Embodiment approach 3

[0014] Specific implementation mode three: the drinking water secondary disinfection method of the present embodiment is completed through the following steps:

[0015] 1. The water in the reservoir 1 is transported to the clean water pool 6 through the water pump 3-1, and the flow of the water is controlled at 2m by the first flow regulating valve 2-1 and the first flow meter 4-1 3 / h, the residence time of water in the clear water pool 6 is 30min, and a metering pump is used to throw Escherichia coli at the water outlet of the water storage tank 1, and the quantity is 1350cfu / L. The chlorine inlet pipe in the gun 5 is completed (the water jet gun 5 in this system adopts the 1420D type product produced by the American Capital Company, and the water jet gun 5 is used to throw chlorine. The total amount of bacteria in the raw water of the experiment is 1400cfu / mL, and the total number of bacteria is between 40 and 60cfu / mL, the surviving amount of bacteria is relatively uniform...

Abstract

A two-stage disinfecting system for the drinking water features that the water gun is additionally used for the water cleaning pool, and the mixing pool with Cl inlet, NH4 inlet and stirrer is additionally used between water pump and regulating valve. Its method features that said water gun is used to apply Cl to water, and the Cl and NH4 are applied for stage-two disinfecting. Its advantage is high and durable disinfecting effect.

Description

technical field [0001] The invention relates to a water treatment system and a water treatment method. Background technique [0002] Most of the traditional drinking water disinfection methods use the chemical agent chlorine in the water for disinfection. Chlorine has the characteristics of high-efficiency sterilization and can quickly inactivate bacteria in water. However, because the existing drinking water disinfection system uses a water ejector Single-stage chlorine injection has poor mixing effect. Therefore, the inactivation effect on bacteria is uneven, the duration is short, and the disinfection by-products produced by chlorine will exceed the national standard, directly affecting people's physical and mental health. Contents of the invention [0003] In order to solve the problems that the by-products of the primary disinfection of drinking water with chlorine exceed the standard and the inactivation effect on bacteria is uneven and the duration is short, the pre...
