Biological combined treatment device for kitchen food wastes

Abstract

The invention discloses a biological combined treatment device for kitchen food wastes. The biological combined treatment device comprises an airtight box, a first guide platform, a filtering platform, a second guide platform, a bottom platform, a residual liquid box, a worm egg feeding channel, a filtering cabin, a gas recovery cabin and a saline water cabin, wherein the first guide platform is arranged as a height gradient type platform; a feeding port and the worm egg feeding channel are arranged on the box; the filtering platform is jointed with the lower end of the first guide platform and the higher end of the second guide platform; the bottom platform is located under the box; the residual liquid box is located under the bottom platform; a through hole on the bottom platform is connected with the residual liquid box; the filtering cabin, the gas recovery cabin and the saline water cabin are placed on the rear side of the first guide platform; gases generated by all the cabins are pumped into the gas recovery cabin for recycling; the saline water cabin is used for concentrating and storing saline water. In the biological combined treatment device for kitchen food wastes, a stereoscopic coexistence space is formed in the airtight box, black soldier flies live on the upper layer and earthworms live on the lower layer, wherein black soldier flies, earthworms and bacteria cooperate with each other for ecologically efficient treatment of the kitchen food wastes.

Description

technical field [0001] The invention relates to the field of waste treatment equipment, in particular to a combined biological treatment device for kitchen waste. Background technique [0002] Kitchen waste mainly refers to the leftovers, leftovers, leftover soup and waste materials produced during the cooking process; currently, the treatment methods for kitchen waste include incineration, landfill, making ecological feed, and aerobic composting , vermicomposting and scavenging insect breeding, etc., among which biological treatment has better comprehensive benefits. Due to the high cost of waste sorting and difficult operation, in actual use, almost no enterprises can collect residents' kitchen waste for centralized ecological treatment. In most cases, most of the kitchen waste that has been sorted by households is simply incinerated or landfilled together with ordinary garbage in the end, which can neither play the residual value of these organic substances nor pollute t...
