TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The system further comprises a draught fan which communicates with the upper part of the glass greenhouse, where the draught fan is connected with an inlet of an absorption tower by a pipeline. A gas discharging hole of the absorption tower communicates with a gas bin in the glass greenhouse. The system further includes a control room with a computer system, where the metering information of sludge high-pressure conveying metering pump, the metering information of auxiliary bin metering control grate and the metering information of the synchronous metering pump are connected with the computer system. The sensor for detecting temperature, humidity, and pH value and oxygen concentration of the fermentation bin is connected with the computer system. The control information of the motor of the air blower, the draught fan, the auxiliary material conveying belt, the material distributing belt, the discharging belt and the conveying belt communicates with the computer system. The inclined fermentation bed is a dual-direction symmetrical inclined fermentation bed, where the plate bed is reversely V-shaped. The plate bed is a porous rubber plate and a layer of non-woven fabric is paved on the plate bed surface and there are 14 fermentation bins. The volume ratio of the sludge, conditioner, heavy metal passivant and microbial inoculum is 100:40-60:10-15:5-10. The passivant is a waste organic substance crushed material. The heavy metal passivant is grass carbon. The microbial inoculum is composite micro organism microbial inoculum. The primary fermentation takes place for 6-9 days, where the temperature increases to 60-70 degrees C from the normal temperature during 2-3 days and then reduces to 55-60 degrees C for fermentation by 4-6 days. The secondary fermentation takes place for 6-9 days, where the temperature is kept at 48-55 degrees C during 4-6 days and reduced to 35-40 degrees C and maintained for 2-3 days. The original moisture content of the sludge is 75-82% and the moisture content of the mixed and stirred material is 60-67%. The moisture content of the materials after primary fermentation is 50-55% and the moisture content of the materials after secondary fermentation is 35-45%. The air blower starts supplying gas, when the materials enter the fermentation bins for fermentation, the gas enters the fermentation bins from gas holes on the plate bed for ventilating and oxygen supplying in forced manner, the hot vapor collected in the glass greenhouse is extracted to the absorption tower by the draught fan through the pipeline and the gas is guided to the gas bin of the inclined fermentation bed after absorbing, drying and deodorizing by the active carbon layer in the tower to assist the newly paved materials to heat up.
