Method for producing microbial thalli protein from livestock and poultry breeding wastewater

Abstract

The invention discloses a method for producing microbial thalli protein from livestock and poultry breeding wastewater. Livestock and poultry breeding wastewater firstly enters a fermentation acid-production reactor, organic matter in the wastewater is converted into volatile aliphatic acid (VFAs), and then volatile aliphatic acid (VFAs) enters a shallow pool anaerobic infrared light reactor; andpurple photosynthetic bacteria use infrared light as an energy source to rapidly synthesize organisms by using organic matter, nitrogen and phosphorus in wastewater as nutrients. Part of the purple photosynthetic bacteria mixed solution discharged by the reactor flows back to the front end of the reactor, and the rest of the purple photosynthetic bacteria mixed solution is discharged as a microbial thalli protein feed. A solar panel is arranged at the top of the shallow pool anaerobic infrared light reactor for power generation, thus providing electric energy for an infrared lamp of the reactor. Thereby, the microbial thalli protein feed is produced efficiently from the livestock and poultry breeding wastewater with the solar energy as the energy source. Pollution of the livestock and poultry breeding wastewater to the environment is controlled, resource is realized, and sustainable development of the livestock and poultry industry is promoted.

Description

technical field [0001] The invention relates to a method for producing microbial cell protein from livestock and poultry breeding wastewater, and belongs to the technical field of sewage biological treatment. Background technique [0002] With the rapid development of my country's economy, people's living standards are gradually improving, and the demand for various meat and poultry and egg foods is increasing, which makes the large-scale and intensive livestock and poultry breeding industry increasingly prosperous, but at the same time It has also caused the problem of livestock and poultry breeding wastewater polluting the water body environment. Livestock and poultry breeding wastewater is mainly composed of livestock and poultry urine, some feces, and flushing water from breeding houses. It contains high concentrations of organic matter, nitrogen, phosphorus and other pollutants. It has good biological treatment and degradation performance; The load is strong, and contai...
