Abstract

The invention discloses a biological preparation for treating high-concentration ammonia-nitrogen wastewater. The raw materials for its preparation are composed of the following components in parts by weight: 10-15 parts of chlorella DH2 algae liquid, fermented bacteria of Pseudomonas hibiscus DT1 Bacillus megaterium NCT-2 fermentation broth 15-20 parts, Acinetobacter baumannii AL-6 fermentation broth 10-15 parts, photosynthetic bacteria fermentation broth 5-10 parts, agar 1-3 3-5 parts of polyvinyl alcohol. In addition, the invention also provides a preparation method of a biological preparation for treating high-concentration ammonia nitrogen wastewater. The present invention utilizes the synergistic effect of heterotrophic nitrifying aerobic denitrifying bacteria and chlorella to efficiently remove ammonia nitrogen in high-concentration ammonia-nitrogen wastewater, and the nitrification process and denitrification process of the present invention are carried out in the same device, and the process is simple and does not require Setting different process combinations not only improves the efficiency of wastewater treatment, but also saves operating costs.

Description

Technical field[0001]The present invention belongs to the field of sewage treatment, and more particularly to a biological agent for treating high concentration ammonia nitrogen wastewater and a preparation method thereof.Background technique[0002]In recent years, with the rapid development of the economic industry and the increase in the trend of people in the urbanization, the total amount of industrial wastewater and sewage discharge increased year by year, while various chemical synthetic products, including fertilizers, pesticides and synthetic detergents, etc. The nitrogen nutrients contained in sewage have increased to the main contaminants. The protrusion of ammonia nitrogen in the water body is the richness, water quality deterioration, affecting the ornamental and tourism value of the water. In addition, ammonia nitrogen and algae material consumption water dissolved oxygen, fish shrimp water vivid plants will die due to a large amount of hypoxia. In addition, nitrite is a...
