Embodiment 1

[0038] refer to figure 1 , Water quality indicators such as geosmin in the drinking water of a food factory exceeded the standard, and a trial production test was carried out on the raw water.

[0039] (1) The water tower supplies the raw water to the raw water tank through the pipeline, and the treated water volume is 250m 3 / h, the water tank is made of SS316 material, the residence time is 3h, the blower is connected to the aeration plate and the aeration pipe installed at the bottom of the original water tank to aerate the original water tank, and the air intake is 5.64m 3 / h. At the same time, add ozone to the original water tank, design and select an adjustable ozone dosing system, the ozone dosing amount is 1mg / L, and the ozone dosing amount can be adjusted according to the actual on-site operation conditions. The ozone generation room is set up separately in the system. The ozone output of the ozone generator is 800g / h, and the ozone output concentration is 130mg / L. I...

Abstract

The invention relates to a process for removing geosmin in raw water of drinking water. The process comprises the following steps: introducing raw water into a raw water tank; carrying out aeration inthe raw water tank by using a blower, and adding ozone into the raw water tank for strong oxidation at the same time; mixing the water out of the raw water tank with a coagulant for a coagulation reaction; carrying out filtration after full coagulation; introducing filtered drinking water into a clean water tank; transporting the treated drinking water to each water use site by using a frequencyconversion water supply device; and arranging disinfection device between the water out of the clean water tank and the frequency conversion water supply device for disinfection treatment. Compared with the prior art, the treatment process provided by the invention has the advantages of high pollutant removal efficiency, high utilization rate of ozone and activated carbon, less dosage, less investment of water treatment equipment, no secondary pollution and the like.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a process for removing geosmin in drinking water raw water. Background technique [0002] With the development of my country's economy and social progress, people's living and production water consumption continues to rise, but on the other hand, due to the limitations and requirements of development, the balance of the ecosystem is destroyed, and the self-recovery ability of water source water becomes poor. The types of pollutants increase accordingly, which constitutes a great hidden danger to people's life, health and survival. Therefore, the safety of drinking water quality has been paid more and more attention by people. The eutrophication of water body can lead to a large number of algae in the water. The algae will not only consume the dissolved oxygen in the water, but also release the smell-causing substances, which will cause the occurrence of drinking water odor...
