Description

Complex flora for treating benzotriazole wastewater Technical Field The application relates to the field of wastewater treatment, in particular to the field of wastewater treatment containing benzotriazole. Background The Benzotriazole (BTA) is an important fine chemical product, is white light brown needle crystal, is widely applied in the industrial field, is mainly used as an antirust agent and a corrosion inhibitor for metals such as silver, copper, nickel and the like, and can also be used as a coating additive, a detergent preservative, a dye intermediate, a high polymer stabilizer and the like. The main stream synthesis process of benzotriazole is prepared by reacting o-phenylenediamine with sodium nitrite. Therefore, the waste water generated in the synthesis and cleaning steps of benzotriazole contains unreacted o-phenylenediamine, excessive sodium nitrite, an acidic catalyst (such as hydrochloric acid) and reaction byproducts besides residual BTA, so that the waste water has complex components. Generally, the wastewater has the remarkable characteristics of high COD, strong biotoxicity, poor biodegradability and high salt content. At present, the main treatment methods are divided into four major categories, namely a physical method, a chemical method, a biological method and a combined process. The biological method utilizes the metabolism of microorganisms to degrade BTA, has the advantages of low cost, environmental friendliness and the like, but needs to overcome the biotoxicity and the nondegradability of BTA. Thus, there is still a need in the art for new microorganisms to effectively treat benzotriazole-containing wastewater. Disclosure of Invention The application aims to provide a microorganism capable of effectively treating wastewater containing benzotriazole, which can realize efficient pretreatment of wastewater and reduce treatment burden for an enterprise activated sludge system. In one aspect, the application provides a strain composition comprising the following strains: (a) The collection number is CGMCC 37186, the bacillus highland (Bacillus altitudinis) SD1, (B) A sewage water microorganism (Aquamicrobium defluvii) SD4 with a preservation number of CGMCC 37187, and (C) Pseudomonas aeruginosa (Pseudomonas aeruginosa) SD32 with the preservation number of CGMCC 37189. In another aspect, the application provides a microbial preparation comprising a strain composition according to the application. In another aspect, the application provides a method for treating wastewater comprising triazole, the method comprising treating the wastewater comprising triazole with a strain composition of the application.

Detailed Description In the present description, unless otherwise specified, the components involved or their preferred components may be combined with each other to form a new technical solution. In the present specification, all embodiments and preferred embodiments mentioned herein can be combined with each other to form new technical solutions, if not specifically stated. In the present description, all technical features mentioned herein and preferred features may be combined with each other to form new technical solutions, if not specifically stated. "Range" is disclosed herein in the form of lower and upper limits. There may be one or more lower limits and one or more upper limits, respectively. The given range is defined by selecting a lower limit and an upper limit. The selected lower and upper limits define the boundaries of the particular ranges. All ranges that can be defined in this way are inclusive and combinable, i.e., any lower limit can be combined with any upper limit to form a range. For example, if ranges of 60-120 and 80-110 are listed for a particular parameter, it is understood that ranges of 60-110 and 80-120 are also contemplated. Furthermore, if minimum range values 1 and 2 are listed, and if maximum range values 3,4, and 5 are listed, then the following ranges are all contemplated as 1-3, 1-4, 1-5, 2-3, 2-4, and 2-5. In the present application, unless otherwise indicated, the numerical range "a-b" represents a shorthand representation of any combination of real numbers between a and b, where a and b are both real numbers. For example, the numerical range "0-5" means that all real numbers between "0-5" have been listed throughout, and "0-5" is simply a shorthand representation of a combination of these values. When a certain parameter is expressed as an integer of 2 or more, it is disclosed that the parameter is, for example, an integer of 2, 3,4, 5, 6, 7, 8, 9, 10, 11, 12 or the like.
