Problems solved by technology

Compared with reforming the reactor, simply supplementing nutrients can greatly improve the efficiency of hydrolysis and acidification, which is easy to implement. Currently, the commercially available hydrolysis and acidification bacteria for water treatment are mainly yeast and lactic acid bacteria, which can only increase the bacteria in the hydrolysis and acidification tank. Concentration, does not enrich and strengthen water treatment functional bacteria

Abstract

The invention discloses a hydrolytic acidification complex microbial inoculant for water treatment and a preparation method thereof. The hydrolytic acidification complex microbial inoculant comprisesa composite microbial flora and nutrient substances. The composite microbial flora is composed of clostridium butyricum, bacillus subtilis, yeast, white rot fungi, rhodopseudomonas, lactobacillus acidophilus, denitrifying bacillus, acinetobacter, lampropedia and thiobacillus denitrificans, and the strains are obtained by a commercial approach. The invention relates to the water treatment field. According to the hydrolytic acidification complex microbial inoculant for water treatment and the preparation method thereof, high-efficiency acid-producing bacteria, high-efficiency hydrolytic bacteriaand water treatment functional bacteria can be reasonably collocated without mutual antagonism, the bioactivity is high, the bacteria content is high, the complex microbial inoculant has rapid propagation speed, can be added into a sewage treatment system according to certain amount, and can enrich the variety and abundance of microorganisms in a hydrolytic acidification tank, and improve the treatment efficiency and operating stability of the biochemical system. The complex microbial inoculant is suitable for the hydrolytic acidification process section of water treatment, and can enhance the capacity and quality of water treatment and lower the operating cost.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a hydrolytic acidification composite bacterial agent for water treatment and a preparation method thereof. Background technique [0002] With the rapid and large-scale development of industry, the huge harm caused by industrial wastewater to the environment threatens the survival of human beings. Countries have formulated wastewater discharge standards and continuously increased discharge requirements to ensure the safety of water resources. This puts higher demands on the wastewater treatment process. [0003] Industrial wastewater has the characteristics of large water volume, high concentration of organic matter, large fluctuations in water quality and volume, and is difficult to degrade, which leads to problems such as poor biodegradability of industrial park wastewater, low degree of microbial degradation, high load of biochemical treatment, and difficulty in subsequ...
