The invention discloses a biochemical treating 
system for kitchen garbage. The biochemical treating 
system comprises an acidizing loading 
machine, an acidizing basin, a crushing sieving 
machine, a 
raw water basin and a water collecting basin. The biochemical treatment for kitchen garbage comprises a bag-breaking step, a loading 
hydrolysis step, an acidizing separating step and a crushing sieving step. The bag-breaking and loading 
hydrolysis steps are arranged, so that the process is simple and the 
technical design is reasonable; the sieving mode of crushing adding water-cleaning is adopted, so that the sieving efficiency is high, the whole process is designed on the basis of streamline operation, the whole operating efficiency is high, the treating speed is high and the effect is obvious; according to the high-level liquid soaking design of the acidizing basin, the acidizing effect for embedded garbage is excellent and the garbage is thoroughly acidized; the pulping fine particle treating mode is adopted, so that during the 
anaerobic treatment process, the 
digestion speed of an anaerobic 
fermentation system is effectively improved, the generation of 
biogas residues is greatly reduced and the 
methane volume is increased; and the anaerobic 
fermentation mode is adopted, so that the traditional 
compost or feed treating mode is changed, the garbage is effectively converted into the 
clean energy, and the surrounding environment is protected.
