Solid waste treatment device and solid waste treatment process

Abstract

The invention provides a solid waste treatment device and a solid waste treatment process, which belong to the field of organic matter treatment. The treatment device comprises an electrohydrolytic ammonia nitrogen separation system, an ammonia nitrogen stripping system and an ammonia nitrogen recovery system. An inlet end of the ammonia nitrogen stripping system is communicated with a main outletend of the electrohydrolytic ammonia nitrogen separation system; a first outlet end of the ammonia nitrogen stripping system is communicated with an inlet end of the ammonia nitrogen recovery system.The treatment device is simple, low in cost, and suitable for treating organic wastes containing ammonia nitrogen matters. The treatment device is used for electrically hydrolyzing solid organic matters to be treated through the electrohydrolytic ammonia nitrogen separation system, the hydrolyzed liquid is input to the ammonia nitrogen stripping system, and NH4<+> in the liquid is input to the ammonia nitrogen recovery system through an ammonia gas way so as to be recycled. The process is simple and short in time consumption, the removal efficiency of the organic matters is favorably improved, the use of an alkaline chemical agent can be reduced and even avoided, and the operation cost is favorably reduced.

Description

technical field [0001] The invention relates to the field of organic matter treatment, and in particular to a solid waste treatment device and a solid waste treatment process. Background technique [0002] Urban organic solid pollutants mainly include household waste, kitchen waste, garden waste, human and animal manure, sludge, and organic domestic waste produced by businesses, service industries, culture, education and health, government agencies, enterprises and institutions, etc. The harmless disposal rate of urban domestic waste in the country is only 63.5%. If urban organic solid waste cannot be treated quickly and effectively, it will produce stench, pollute groundwater, spread diseases, and pose a great threat to urban public environmental health and safety. [0003] At present, solid waste treatment devices are not only bulky and occupy a large area, but also usually require a large amount of alkaline chemicals, which is expensive. Therefore, it is necessary to im...
