stirring: the tail mud of the waterworks, the first product and the strain which are added in proportion enter a continuous stirrer to be stirred to form a mixture, wherein the tail mud of the waterworks is 4.5 to 5.5 tons, the first product is 2.5 to 3.5 tons, and the strain is 0.5 to 1 kilogram.
Preferably, the amount of the tail mud of the waterworks is 5 tons, the amount of the first product is 2 tons, and the amount of the strain is 1 kg.
During stirring, the tail mud is mixed by using a double-shaft feeding screw, the tail mud is added into a double-shaft stirring and stirring machine in proportion, and the purpose of adjusting the adding amount of the tail mud is achieved by controlling the rotating speed of double-shaft feeding; the first product is also proportioned by using a double-shaft feeding screw, and is added into a double-shaft stirring and splicing machine in proportion, and the purpose of adjusting the adding amount of the first product is achieved by controlling the rotating speed of double-shaft feeding; the strain is proportioned by using a feeding screw in the strain, the strain is added into a single-shaft screw feeder in proportion, and the purpose of adjusting the adding amount of the strain is achieved through the rotating speed of the screw feeder. All the rotating speed regulation is carried out through a frequency converter, so that the adding amount of various materials is controlled. Adding the sludge, the first product and the strain in proportion, feeding the mixture into a continuous stirrer for stirring, feeding the mixture from one end of the stirrer, discharging the mixture from the other end of the stirrer while feeding, and conveying the stirred mixture out through a belt conveyor. Then evenly distributing the mixture into a fermentation tank through a forklift or a belt conveyor for high-temperature fermentation. And starting the turner to turn over the materials after the temperature of the materials entering the fermentation tank is raised to 50-60 ℃. The turning purpose is mainly three: firstly, the water evaporated at high temperature when the material is fermented is emitted. And secondly, timely supplying oxygen to the materials. Thirdly, the material is displaced and pushed from the feeding end to the discharging end of the fermentation tank. The material can be moved by 3-4 meters by improving the large span and turning over once. In order to improve the fermentation effect, shorten the fermentation period and reduce the fermentation cost, a sunlight shed is used in a fermentation workshop, and the temperature of the fermentation workshop can be increased by the sunlight shed.
In one embodiment, a method of high temperature oxygen-consuming fermentation comprises:
uniformly distributing the mixture into a fermentation tank through a belt conveyor for high-temperature fermentation;
and after the temperature of the mixture entering the fermentation tank rises to 50-60 ℃, starting a turner to fully turn and throw the mixture for 1-2 times every day, so that full fermentation is realized and decomposition is accelerated.
After the fermentation tank is fermented at high temperature for about 20-30 days, the materials are basically decomposed, and at the moment, the materials can be transferred out of the fermentation tank and piled into a warehouse for aging or secondary fermentation. If the conditions of the fermentation tank allow the suggested time for stacking the materials in the fermentation workshop to be as long as possible, the materials are fully decomposed, and the quality of the organic fertilizer is improved.

Through the deodorizing bacteria, the generation of odor in the fermentation process can be effectively inhibited, and the fermentation environment is improved. In the later turning process, a relatively good fermentation environment can be basically obtained by spraying the water agent of the deodorizing auxiliary agent.
Secondly, foul gas is collected and deodorized. The addition of biological deodorants during the fermentation still produces a more or less low level of off-flavours. The peculiar smell generated in the fermentation process is mainly ammonia generated in the fermentation process, and the deodorization is carried out twice by adopting a method of sealing, dehumidifying, adding alkali washing and water washing in practice, so that a good deodorization effect is obtained. Better deodorization effect can be obtained after biological deodorization and foul gas collection, washing and deodorization, and no secondary pollution is generated to the surrounding environment.
