Biochemical treating system for kitchen garbage

Abstract

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.

Description

technical field

[0001] The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste biochemical treatment system. Background technique

[0002] Kitchen waste refers to the residues of raw materials and finished products used in family life and diet, and the leftovers of meat, fruit and vegetables in restaurants, hotels and markets. As a part of domestic waste, kitchen waste has been paid more and more attention to its reduction and recycling as a worldwide problem, and it has become one of the problems that must be faced and solved.

[0003] The basic foothold of foreign kitchen waste is on-site reduction treatment, and the treatment devices are roughly divided into mechanical grinding type and biochemical treatment type. The principle of mechanical grinding is to chop all kinds of food waste in the inner tank through the high-speed blade, and then flush the mixture into the sewer. In the United States, more than 90% of househol...
