Abstract

The invention discloses a disinfectant and its application in biological sewage treatment; the disinfectant comprises: a mixture of zingerone derivatives, trichloroisocyanuric acid, sodium silicate, isovalerylshikonin and monosodium citrate The steps include: in parts by weight, dissolving the zingerone derivative in ethanol, stirring and dissolving to obtain a solution A; adding trichloroisocyanuric acid and sodium silicate to distilled water, stirring and dissolving to obtain a solution B; Add solution A to solution B, stir and mix uniformly to obtain solution C; add the mixture of isovalerylshikonin and monosodium citrate to solution C, stir and mix uniformly to obtain a disinfectant. The prepared disinfectant has a high sterilization rate (iron bacteria, sulfate reducing bacteria and Bacillus cereus), and a disinfectant with excellent stability; the disinfectant is efficient, safe and broad-spectrum, and does not cause corrosion to equipment , so that it has a wide range of applications in biological sewage treatment.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a disinfectant and its application in biological sewage treatment. Background technique [0002] With the rapid development of social economy and the continuous acceleration of urbanization process, indoor and outdoor environmental pollution is always becoming more and more prominent. People's attention to environmental pollution has shifted from outdoors to indoors, and an important cause of pollution is the large discharge of urban wastewater, including domestic sewage and industrial wastewater. Therefore, the treatment of sewage is an urgent problem to be solved in our country; our country has taken many measures to effectively treat sewage. Sewage mostly adopts biological treatment process, among which the common ones are activated sludge method, biofilm method and anaerobic digestion method, etc.; and biological sewage treatment method is currently an efficient water treatment process, tha...
