The Research on the Effect of Br-Antibacterial Agents to Whitewater

Abstract:

This paper concerns with two brominated bacteriostatic agents, using the condition-test to research the inhibitory effect of the microorganisms in the waste paper pulp white water. Using the coated plate culture method of adding different amounts of antibacterial agents in Whitewater, the bacteria and mold in nutrient agar and potato medium experiments were used to observe the inhibitory effect. The results showed that the chosen brominated bacteriostatic agents (PS-2890, GB-3612) in this paper have a better antibacterial effect and 1#is better than 2#,the bacteriostatic agent can be chosen according to the actual situation of the plant .The bacteriostatic agent will achieve a higher rate of bacteriostasis when it is added to 5ppm, and this added amount can also meet the requirements of the factory on the prevention and treatment of microbial. The rate of bacteriostasis generally reached 40% -80% ,the highest 92.8%,when the antibacterial dosage is 3ppm-7ppm.
