Abstract

The invention discloses a method for preparing a compound fertilizer through stirring type temperature feedback aerobic / anaerobic sludge garbage composting. A device for preparing a compound fertilizer through stirring type temperature feedback aerobic / anaerobic sludge garbage composting consists of a composting tank and a temperature feedback adjusting system, wherein a spiral propulsion device is mounted on the central axis position of the composting tank; the lower end of the spiral propulsion device is connected with a reversing motor which is used for controlling the forward and backward operation of the spiral propulsion device so as to realize physical and biological effects of the mixture and obtain compost; and urea, monoammonium phosphate, potassium chloride and calcium superphosphate are added, and the materials are stirred and mixed to obtain a compound fertilizer. The method disclosed by the invention is convenient to operate and environment-friendly, realizes efficient composting and provides practical convenience to the fertilizer preparation through compositing of garbage sludge and organic matters.

Description

technical field [0001] The invention relates to a method for completing the aerobic anaerobic (OA) composting of sludge garbage by using a multifunctional screw propeller under the condition of temperature feedback, and realizing mixing with inorganic fertilizers to make compound fertilizers. Background technique [0002] Composting is a harmless treatment that uses the metabolism of aerobic and anaerobic microorganisms to degrade and stabilize organic matter under medium-high temperature and aerobic conditions under artificial control conditions. The process of converting into stable humus; at present, the research on composting devices in China includes: Chen Shihe et al. developed the DANO test model, the characteristics of the DANO composting reactor, and used the DANO dynamic composting process to treat domestic waste; Zhou Shaoqi et al. The alternating anaerobic and aerobic composting of garbage has been carried out to a certain extent, which provides a theoretical bas...
