Problems solved by technology

Anaerobic fermentation technology is an effective means to solve these problems, but due to the concentration of various high nitrogen-containing organic matter and the low anaerobic digestion performance of wastewater, and the weak methane production capacity, the efficiency of anaerobic fermentation is reduced. Solving these problems is currently the field of environmental protection research. one of the problems

Abstract

The invention belongs to the field of anaerobic fermentation of agricultural waste, and particularly relates to an anaerobic fermentation treatment method for superhigh-temperature synchronous biological hydrolysis and deamination. An anaerobic fermentation treatment system comprises a gas circulating pump (18), an acid absorption tank (22), an anaerobic reactor (3) and a first peristaltic pump (37). According to the anaerobic fermentation treatment system, during anaerobic fermentation, gas generation capacity of is improved obviously, and methanogenesis potentiality of high-concentration organic waste is enhanced. The anaerobic fermentation treatment system has the advantages that anaerobic fermentation efficiency is improved, and organic matters in the waste are utilized sufficiently; the ammonianitrogen content is reduced obviously during fermentation, inhabitation on the anaerobic fermentation process by ammonianitrogen is relieved, the microbial activity in the whole fermentationprocess is improved, and waste treatment capacity in anaerobic fermentation is further improved.

Description

Technical field[0001]The invention belongs to the field of anaerobic fermentation of agricultural wastes, and particularly relates to an anaerobic fermentation method of ultra-high temperature biological hydrolysis and simultaneous deamination.Background technique[0002]With the increase of our country’s population and the acceleration of urbanization, people’s demand for material life has increased dramatically every day. Therefore, in order to meet the needs of society, the development of agriculture and industry has also developed rapidly. However, the rapid development of industry and agriculture in the production process to meet people's needs has also brought serious pollution to the ecological environment. The large amounts of high-nitrogen organic sewage and livestock manure discharged by various food processing plants and farms far exceed the environment. The bearing capacity has caused great damage to the environment.[0003]At present, the domestic methods for treating high-...
