Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, it is inconvenient to add other materials to the inside of the tank when the existing microbial agent preparation device is preparing the microbial agent. When adding materials to the inside of the tank, there will be some impurities along with the The air enters the inside of the tank together, which affects the purity of the microbial inoculum produced. The present invention proposes a microbial inoculum for treating high-salt industrial wastewater and its preparation method

Abstract

The invention belongs to the technical field of microorganisms and sewage treatment, and particularly relates to a microbial agent for treating high-salt industrial wastewater. The microbial agent is prepared from the following raw materials in parts by weight: 20 to 28 parts of activated sludge, 11 to 13 parts of quaternary ammonium salt lignin flocculate, 16 to 20 parts of small-particle activated carbon, 35 to 45 parts of microbial liquid and 5 to 10 parts of antioxidation buffer agent. Microbial florae are enabled to have an adherent carrier, the added quaternary ammonium salt lignin flocculant enables the microbial florae, activated sludge and small-particle activated carbon to be combined, so that the microbial agent does not need to be stored in a low-temperature environment. The preparation method of the microbial agent for treating the high-salt industrial wastewater comprises the following steps: firstly, the antioxidation buffering agent enters a mixed material through a feeding pipeline, a feeding hole in a mixing device, a hollow rotating shaft and a spraying device on one side of a stirring rod, other microorganisms are prevented from entering the microbial agent from a feeding port along with the anti-oxidation buffering agent after the feeding port is opened, and the microbial agent is prevented from being polluted to influence the purity of the product.

Description

technical field [0001] The invention belongs to the technical field of microorganisms and sewage treatment, in particular to a microbial bacterial agent for treating high-salt industrial wastewater and a preparation method thereof. Background technique [0002] High-salt, refractory industrial wastewater not only causes serious pollution to the environment, but also increasingly harms the human body, aquatic organisms and crops, seriously destroying the ecological balance. For a long time, the treatment of high-salt wastewater has been a difficult problem in the field of sewage treatment. [0003] There have also been some technical solutions about microorganisms and sewage treatment in the prior art. A Chinese patent with the application number CN103540555A discloses a method for preparing a salt-tolerant microbial bacterial agent. Under the condition that the total salt concentration is 1-30%, the salt-tolerant microbial flora in the high-salt environment sample is mixed; ...
