Abstract

The invention discloses a complete mixing type sludge treatment method, which comprises the following steps of: forming a composting fertilizer by taking sludge of a municipal sewage treatment plant as a composting raw material and taking straws and mushroom sticks as composting auxiliary materials, performing aerobic composting, reserving a part of area at the front end of a fermentation tank as a feeding area, and reserving a part of area at the rear end of the fermentation tank as a discharging area, reserving a middle area a fermentation area, distributing a compost to the middle area of the fermentation tank, wherein the materials reach the edge of the discharging area; conveying 20-30% of the materials to the next equipment, returning 70-80% of the materials to the feeding area, and distributing sludge of a town sewage treatment plant above the returned materials till the discharging amount is equal to the discharging amount at the edge of the discharging area. Materials in a high-temperature stage are arranged at the bottom of the newly-added sludge of the municipal sewage treatment plant in the fermentation process, the temperature of the newly-arranged sludge of the municipal sewage treatment plant on the upper layer can be rapidly increased, the temperature rise rate of the materials in the early stage is greatly increased, the fermentation period is stable, and the treatment capacity of the sludge is increased.
