The application provides a strain of Candida zeylanoides, and applications of the strain in inhibiting Botrytis cinerea and in wine brewing, the Candida zeylanoides is numbered SIVE8902, has been preserved in the China Center for Type Culture Collection on July 22, 2024, the preservation number is CCTCC NO:M 20241637, and the Latin name is Starmerella bacillaris The strain has a strong inhibiting effect on Botrytis cinerea in grape fresh fruits and vineyards, can reduce the growth and reproduction of Botrytis cinerea in the fruits, and meanwhile, compared with single fermentation of Saccharomyces cerevisiae, the sequential fermentation of the Candida zeylanoides and Saccharomyces cerevisiae adds ethylguaiacol and 4-ethyl-2-methoxyphenol, adds spice and honey flavors to the wine, greatly improves the total amount of volatile phenolic compounds in the wine, and improves the wine quality.

The present application relates to a kind of coal chemical industry wastewater multistage processing method, belong to wastewater treatment technical field.The organic matter removal agent in the coal chemical industry wastewater multistage processing method of the present application has good removal effect to multiple organic matters (including lipophilic organic matter volatile phenol, thiophene, pyridine, quinoline, furan, naphthalene, anthracene, phenanthrene and hydrophilic organic matter carbazole, indole and pyrrole) in coal chemical industry wastewater of different pH.The coal chemical industry wastewater multistage processing method of the present application is not sensitive to the pH of wastewater, and the applicability is wider, can process multiple different pH wastewater, save pretreatment step, reduce processing cost.The carbonic acid dimethyl ester and amide oxime in the organic matter removal agent in the coal chemical industry wastewater multistage processing method of the present application have synergistic effect, both can play synergistic effect, improve the removal rate of multiple organic matters in coal chemical industry wastewater.

The present application relates to sewage treatment technical field, disclose a kind of oil refining stripping purification water sewage resource utilization method, the method comprises the following steps: refinery sulfur-containing ammonia-containing acidic water is divided into high phenolic acidic water and low phenolic acidic water according to the concentration of volatile phenol contained;The high phenolic acidic water is treated by first stripping, and high phenolic stripping purification water is obtained;The low phenolic acidic water is treated by second stripping, and low phenolic stripping purification water is obtained;The high phenolic stripping purification water and low phenolic stripping purification water are respectively reused.The present application adopts high phenolic stripping purification water and low phenolic stripping purification water stripping purification water source head quality collection and double-tower device quality processing, realizes the quality direct reuse mode of high water high use low water low use, system improves the stripping purification water sewage resource utilization efficiency of refinery, realizes the maximum utilization of refinery stripping purification water sewage resource.
