Embodiment 1

[0041] This embodiment provides a biodigestion treatment process for the odor generated by the food waste treatment equipment, which is applied to the odor digestion system for the food waste treatment equipment in Example 1. Such as figure 1 and 2 As shown, according to the processing sequence, the following processing steps are included in sequence:

[0042] S1: Collect the gas overflowing or generated in the sorting table and biochemical reaction chamber in the food waste treatment equipment.

[0043] S2: The gas collected in the above step is subjected to spraying treatment. The spraying treatment includes at least four stages in turn, and the four stages are respectively treated with neutral, alkaline, acidic and neutral spray liquids.

[0044] Wherein, the spray treatment process is completed in the spray tower, and the spray tower is selected to have four-stage spray chambers arranged horizontally. Wherein, a soda ash solution with a pH value greater than 8.5 and les...

Embodiment 2

[0059] This embodiment provides an odor digestion system for kitchen waste treatment equipment. The system adopts the biological digestion treatment process in Embodiment 1 to treat odorous substances in kitchen waste. The system can fully digest all kinds of odorous substances produced in the process of food waste treatment, and achieve the effect of complete deodorization.

[0060] The food waste treatment equipment using the odor digestion system includes: unloading platform, sorting platform, crushing system, dehydration system, transmission system and biochemical reaction chamber. Among them, the sorting platform is used to sort out the non-degradable garbage in the kitchen waste; the biochemical reaction chamber is used to ferment the dehydrated solids of the kitchen waste and convert them into usable organic fertilizers.

[0061] Such as Figure 4-6 As shown, according to the sequence of the treatment process, the odor digestion system provided by the present invention...

Abstract

The invention relates to the field of environmental protection, in particular to a biological digestion treatment process for odor generated by kitchen waste treatment equipment. According to a treatment time sequence, the process sequentially comprises the following treatment steps: S1, gas in kitchen waste treatment equipment is collected; S2, the collected gas is subjected to spraying treatment; S3, gas-mist separation is carried out on the sprayed gas mixture; S4, the gas is subjected to photocatalytic cracking treatment under irradiation of high-energy ultraviolet light beams, and a treated gas mixture is collected; S5, the gas mixture is adsorbed, and residual gas after adsorption is collected; and S6, the residual gas in the previous step is introduced into a biological digestion bin, wherein the biological digestion bin contains a prepared biological digestion solution, and the biological digestion solution contains microbial flora composed of rhodopseudomonas, lactobacillus acidophilus, bacillus polymyxa and acinetobacter. The problems that in the kitchen waste treatment process, the odor treatment difficulty is large, the digestion efficiency is low, and the treatment cost is high are solved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a biodigestion treatment process for odor generated by kitchen waste treatment equipment. Background technique [0002] Food waste contains a large amount of discarded food or food residues, which may contain germs or harmful substances, so they cannot be eaten by poultry or livestock. The current mainstream food waste treatment process is to separate the solid and liquid after crushing and stirring the waste. The separated solid matter is fermented for compost production, and the separated liquid matter can be used for biofuel extraction or biogas production. [0003] During the operation of the food waste treatment station, it is easy to produce the smell of garbage decay and garbage fermentation. These odors are mainly spilled during the process of sorting, crushing and pressing of garbage, or during the degradation and fermentation reaction. The overflow of these odo...
