без добавки химического продукта. Эффективность предотвращени  роста бактерий оценивают по степени подавлени  СВБ, которую определ ют по формулеwithout the addition of a chemical product. The effectiveness of preventing the growth of bacteria is assessed by the degree of suppression of SSC, which is determined by the formula

где С и С, - содержание сероводорода в исследуемой и контрольной пробе (мг/л) по истечении 15 сут после начала испытаний.where C and C are the hydrogen sulfide content in the test and control sample (mg / l) 15 days after the start of the test.

The table shows the results of determining the degree of reduction of sulfate reducing bacteria at the corresponding concentrations of polyoxyethylene chloride. For comparison, the results obtained under similar conditions using acrolein by a known method are given.

У1з таблицы видно, что предлагаемый реагент обеспечивает высокую степень подавлени  роста СВБ. Так, уже при концентрации 0,0005% полиоксиэтиленхлорид обеспечивает степень подавлени  88%, в то врем  как в известном способе эти результаты достигаютс  при концентрации акролеина выше 0,1%,From the table it can be seen that the proposed reagent provides a high degree of inhibition of the growth of sulfate reducing bacteria. Thus, already at a concentration of 0.0005%, polyoxyethylene chloride provides a degree of inhibition of 88%, while in the known method these results are achieved with an acrolein concentration higher than 0.1%,
