Abstract

A gas-water mixing pump is mounted at the lower part of a finished water tank, a suction inlet is connected with the finished water tank, and an ozone pipe joint mounted at the suction inlet is connected with an ozone generator through a one-way valve; an outlet of the gas-water mixing pump is connected with the middle part of the finished product water tank through a water outlet pipe; a stainless steel tail gas pipe is arranged at the top of the finished water tank; an ultraviolet lamp is arranged in the tail gas pipe; the produced water inlet pipe is mounted on the central axis of the finished product water tank; and a produced water outlet pipe is arranged at the lower part of the finished water tank and is provided with a sampling valve. The gas-water mixing pump and the waterway system are modified from a common self-suction impeller pump, the gas-water mixing rate is greater than or equal to 95%, and the productivity is increased by 50% compared with that of a conventional process; the ultraviolet/ozone advanced oxidation method tail gas treatment device is adopted, the power consumption is one fifteenth of that of a thermal decomposition method, and the tail gas emission ozone concentration is smaller than or equal to 0.2 mg/L.

Description

technical field [0001] A drinking water disinfection device, in particular to a drinking water ozone disinfection gas-water mixing device and a tail gas treatment device. Background technique [0002] Disinfection and sterilization (abbreviation: disinfection, killing, sterilization, killing) is an essential process for drinking water production stipulated by the national food production license. Most of the disinfection in water treatment is based on ozone disinfection. Ozone can decompose in water to produce monatomic oxygen (O) and hydroxyl radicals (OH) with strong oxidizing ability. It has broad-spectrum killing microorganisms and deodorizing effects, and its sterilization speed is 300-600 times faster than chlorine. Ozone water disinfection has a sterilization threshold of about 0.3mg / L. When the residual ozone concentration of ozone water reaches the sterilization threshold, the killing effect occurs instantaneously, and 100% of bacteria are killed within 0.5 to 1 mi...
