Abstract

The invention provides a functional composite biological nutrient for the biochemical treatment of industrial wastewater. The functional composite biological nutrient is prepared by adopting the following steps: pulverizing a certain weight percentage of sodium phosphate, ferrous sulfate, magnesium sulfate, potassium chloride, zinc chloride, calcium carbonate, EDTA-2Na, starch, diammonium phosphate, ammonium molybdate, sodium silicate and copper sulfate into fine particles by a pulverizing machine, and agitating and mixing under the conditions of normal temperature and normal pressure after the fine particles are greatly larger than or equal to 20 mesh sieves. The invention has rich nutrition and high energy efficiency, is mainly used for the growth and the succession of microorganisms during the biochemical treatment process of the industrial wastewater and the quick and mass propagation of the microorganisms under the severe environment, promotes the formation of a zooglea with goodstructure, shields the toxicity of chemical leftovers to the microorganisms, accelerates the biochemical reaction, improves the treatment effect of a biochemical system, and particularly enables the biochemical treatment system to be quickly recovered as a buffer agent and a nutritive substance when the quality and the amount of the industrial wastewater are changed or sudden accidents occur.

Description

technical field [0001] The invention belongs to the technical field of biochemical treatment of industrial wastewater, and in particular relates to a multifunctional composite biological nutrient for biochemical treatment of industrial wastewater. Background technique [0002] Today, with the serious pollution of water resources and the increasing demand for water, the importance of sewage purification is also increasing. The treatment of industrial and agricultural wastewater and domestic sewage has attracted widespread attention, and various water treatment methods have been researched one after another. In various sewage treatment technologies, especially the biochemical treatment process of sewage, the process method based on activated sludge method is mostly used. The pollutants in the body are degraded to achieve the purpose of removing pollutants. However, as for industrial wastewater, it lacks relatively complete nutrients suitable for microbial growth like domestic...
