Abstract

The invention discloses a compound biological synergist for petrochemical wastewater treatment and a preparation method thereof. The compound biological synergist comprises a complex flora and nutrients, wherein the complex flora is Rhodopseudomonas, Rhodospirillum rubrum, Lactobacillus acidophilus, Pediococcus, Bacillus subtilis, yeast, Acinetobacter, Lampropedia sp. and Thiobacillus denitrificans, and the nutrients are sodium humate, glucose, citric acid and glutamic acid coagulate. The invention relates to the technical field of water treatment. By using the compound biological synergist for petrochemical wastewater treatment and the preparation method thereof, the problems that petrochemical wastewater is susceptible to impact and microorganism poisoning is well solved, By adding high-efficiency bacteria and nutrients, the invention enhances the impact resistance and toxicity resistance of the biochemical system, improves the effluent quality, can improve the load for treating organic pollutants and the stability of microbial structure, improves the ability of the biochemical system to resist toxic and harmful substances, and provides reliable guarantee for further improving the effluent quality.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a composite biosynergist for petrochemical wastewater 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 wastewater treatment. requirements. [0003] Wastewater in the petrochemical industry generally has the characteristics of large water volume, unstable water quality, complex components, and toxic effects on microorganisms. Wastewater contains a large amount of oil, sulfide, volatile phenols and other substances, COD Cr 、BOD 5 , TDS is also high, it has strong toxicity and impact on the biochemical system, the tre...
