Problems solved by technology

[0004] However, in the process of actual use, due to the complex composition of sewage, after adding the microbial agent required by the biofilm method, the wastewater treatment system may still face various problems. For example, after adding the agent, the number of effective bacteria is small and the activity is limited. , the efficiency of the treatment system is low, it is difficult to quickly form bacterial micelles, and the impact resistance is weak, etc.

Abstract

The present invention discloses a biological accelerator for sewage treatment. The biological accelerator comprises, by weight, 40-60% of carbohydrate, 10-30% of amino acid, 5-15% of vitamin, 2-8% of an inorganic salt, 0.1-1% of a surfactant, 0.1-2% of a growth promotion factor, and 10-20% of a powder carrier. Accordingly the present invention further provides a preparation method and a feeding method for the biological accelerator for sewage treatment. The biological accelerator of the present invention has advantages of low raw material cost, easy raw material purchasing, long storage time and convenient and rapid feeding, can increase the sewage biomass within a short time, can improve the system stability and the sewage treatment capacity, and does not damage the system ecology.

Description

technical field [0001] The invention relates to the field of biological agents, in particular to a biological growth promoter for sewage treatment, a preparation method and an application method thereof. Background technique [0002] With the development of industry and agriculture in our country and the continuous increase of population, whether it is urban sewage, industrial sewage or agricultural nutrient-rich sewage, the technological development of sewage treatment has been put on the agenda. The amount of sewage has increased sharply, and it is common for sewage to be directly discharged into rivers without treatment, resulting in a decrease in the carrying capacity of surface water bodies, and the pollution problem has become increasingly prominent, seriously restricting the economic development of cities and industries, and threatening people's health. [0003] In recent years, much of the major progress and development in the field of water treatment has focused on ...
