Kitchen waste biological treatment system

Abstract

The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste biological treatment system. The kitchen waste biological treatment system comprises a discharging chamber, a buffer pool, a solid material conveyor, a sorting chamber, a pulverizer, a biological treatment device and a fertilizer recovery device which are sequentially arranged, an oil-water separator is further arranged below the buffer pool, the oil-water separator is further connected with a waste oil tank, and the buffer pool comprises a solid-liquid separation tank and a liquid storage tank which are arranged up and down. The liquid storage tank is connected with the oil-water separator, and the oil-water separator is connected with sewage treatment equipment. According to the kitchen waste biological treatment system, kitchen waste is smashed, solid and liquid classification is conducted on the kitchen waste, and therefore conditions are created for subsequent processing, and the key problems of rotting and stinking in the kitchen waste treatment process are solved.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste biological treatment system. Background technique [0002] Kitchen waste, commonly known as swill, also known as swill and swill, is the domestic waste formed by residents in the process of daily consumption. It is easy to rot and deteriorate, emits foul smell, and spreads bacteria and viruses. The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. From the chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. In terms of chemical composition, there are starch, cellulose, protein, lipids and inorganic salts, etc., and its characteristics are as follows: 1. The content of organic matter such as crude protein and crude fiber is high, and the value of development and utilization is high, but it is perishable and produces stench; 2. 1. High w...

AI Technical Summary

Problems solved by technology

In terms of chemical composition, there are starch, cellulose, protein, lipids and inorganic salts, etc., and its characteristics are as follows: 1. The content of organic matter such as crude protein and crude fiber is high, and the value of development and utilization is high, but it is perishable and produces stench; 2. 1. High water content, inconvenient to collect and transport, and easy to cause secondary pollution if not handled properly; 3. The content of oil and salt is higher than other domestic waste, which has a greater impact on the quality of resource-based products and requires a lot of processing costs. Therefore, kitchen waste The disposal and whereabouts of surplus garbage has become an urgent problem to be solved

[0003] At present, the existing large-scale treatment methods commonly used include incineration, composting, etc.; but the above-mentioned methods all face problems such as large area, high cost of long-distance transportation, low efficiency, and low degree of resource utilization.

As a result, most cities in our country cannot effectively deal with food waste; even some illegal behaviors have appeared, such as: recycling food waste by oneself for feeding livestock or making "waste oil"
