Abstract

The invention discloses an early warning regulation and control method based on anaerobic digestion unbalance microorganism resistance enhancement. The method comprises the following steps: carrying out researches through various impact load tests, and in a self-controlled continuous single-phase anaerobic digestion reactor, carrying out water bath heating, controlling the temperature within 35-38DEG C, carrying out online real-time monitoring on pH values and temperatures, at a redox potential, taking kitchen waste samples from different types of catering departments of school canteens and restaurants around, collecting, mixing according to a certain ratio, removing impurities, crushing into slurry, and preserving at 4 DEG C for later use, wherein an organic load of stable operation of asystem is set as 3.0kgVS*m<-3>d<-1>, the temperature inside the reactor is controlled as 35-38 DEG C, and a pH value change range is 7.40-7.80. The method has the beneficial effects that a resistantmicrobial ecological resistance early warning mechanism in a kitchen waste anaerobic digestion unbalance process is explored and analyzed, and a kitchen waste anaerobic digestion unbalance biologicalearly warning mechanism is established.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to an early warning and control method based on strengthening the resistance of anaerobic digestion imbalance microorganisms. Background technique [0002] The common problems in the food waste treatment process are low treatment efficiency and unstable operation, especially the anaerobic treatment system of food waste is easily out of balance. In order to avoid process failure, some anaerobic digestion plants in Europe and the United States usually operate under low load (Ahring, 2003), but this will affect the economic benefits of anaerobic digestion treatment plants due to lower operation and gas production efficiency. [0003] Anaerobic digestion of food waste is an important way to solve a series of social and people's livelihood problems such as "swallow pigs" and "waste oil" that endanger people's livelihood and health, and environmental pollution. However, fo...
