Problems solved by technology

However, the current treatment methods cannot completely and effectively deal with fusel oil
[0007] At present, there are no relevant reports and literature disclosures on the use of fusel oil for activated sludge maintenance, mainly due to the following reasons: 1. The composition of fusel oil is complex. If it is used as a curing substance to provide carbon sources and energy for microorganisms, it cannot be accurately Control its dosage, if the control is not good, it will easily lead to the death of microorganisms in a large area; 2. Fusel oil itself is toxic and cannot be directly used for activated sludge maintenance. The applicant found during the research and development process that the toxicity of fusel oil is mainly due to its Contains aldehydes, which can cause protein denaturation and cause microbial death

Abstract

The invention discloses an active sludge maintenance substance prepared through fusel oil and a preparation method and system of the active sludge maintenance substance. The preparation method of theactive sludge maintenance substance comprises the steps of S1, detoxification; S2, pH adjustment. The preparation system of the active sludge maintenance substance comprises a fusel oil oxidation device, a stirring tank, a weak base tank and a pH adjustment tank. The active sludge maintenance substance has the advantages that with the fusel oil which originally belongs to dangerous waste as a rawmaterial, through the steps of detoxification and pH adjustment, the active sludge maintenance substance is prepared. On one hand, the problem is solved that the fusel oil cannot be thoroughly and effectively treated; on the other hand, the prepared active sludge maintenance substance belongs to liquid and is applied to an active sludge system and evenly dispersed, and it can be guaranteed that the maintenance effect on active sludge is even and the maintenance efficiency for the active sludge is high, so that the active sludge reaction is continuously and stably conducted, and the sewage treatment efficiency is improved. During use, by controlling the content of COD of the active sludge system, it is guaranteed that the active sludge maintenance substance provides a carbon source and energy for microorganisms of the active sludge system, and the situation of mass death of the microorganisms is avoided.

Description

[0001] Technical field: [0002] The invention relates to the field of coal chemical industry, in particular to a method and a system for preparing activated sludge conservation materials by using fusel oil. [0003] Background technique: [0004] Activated sludge is a bacterial gel group composed of microbial groups and their attached organic and inorganic substances, and is mainly used to treat organic matter in sewage. Activated sludge reaction is a process in which complex microorganisms and organic nutrients in sewage form a complex food chain. During the growth and reproduction of microorganisms, organic matter in sewage provides carbon sources and energy for microorganisms, and organic matter in sewage is utilized and consumed. Ultimately achieve the purpose of sewage treatment. [0005] For the batch activated sludge reaction, in the initial stage of the activated sludge reaction, a large number of microorganisms grow and multiply and quickly consume the organic matter...
