Embodiment Construction

[0019] Such as figure 1 As shown, after passing through the grinding equipment in the front stage, the food waste slurry after adding water to grind and pulverize enters the food waste centralized treatment equipment of the present invention through the pressure pipe. The equipment can be made of fiberglass or reinforced concrete, and can be buried or placed indoors. In this equipment, the fine food waste particles in the slurry are liquefied and decomposed through physicochemical electrolysis and biochemical decomposition of special bacteria, so that the slurry is converted into high-concentration organic sewage. Then the sewage enters the biochemical degradation zone. Under the action of aerobic bacteria, the high-concentration kitchen waste organic wastewater is gradually degraded into low-concentration sewage or even reclaimed water. Finally, the effluent can be discharged to the municipal sewage pipe network or further treated and utilized.

Abstract

The invention relates to a small-scale kitchen garbage centralized processing technology. The technology comprises the following steps: the ground and crushed kitchen garbage slurries by adding water is entered in a kitchen garbage centralized processing device by a pipeline under pressure. In the device, the effects of physicochemical electrolysis and special bacteria biochemical decomposition are used for liquefaction and decomposition of fine kitchen garbage particles, thereby the slurries is conversed to the organic sewage with high density. The sewage is reentered in a biochemical degradation zone, under the effect of anaerobic bacteria, the kitchen garbage organic waste water with high density is gradually degraded to the sewage with low concentration even the reclaimed water. The effluent can be discharged to municipal sewage pipes or be processed and utilized. The processing technology of the invention has the advantages of scientific and reasonable design, low processing cost, short period, simple device and flow and strong operationality. The processing technology of the invention is suitable for centralized processing small-scale kitchen garbage generated in novel dwelling house districts, high-grade restaurants, hotels and the like.

Description

technical field [0001] The invention relates to the technical field of kitchen waste disposal. Background technique [0002] Food waste refers to leftovers, expired food, leftovers, waste and other wastes formed in the process of processing and consuming food in restaurants, hotels, canteens of enterprises and institutions, and households. At present, the treatment of food waste is mainly landfill and incineration as domestic waste. On the one hand, such treatment wastes the recyclable resources in food waste, and in addition, the high-salt and high-moisture characteristics of food waste are not suitable for landfill and incineration. deal with. Now some food waste is processed by biochemical technology and used as raw materials to produce fertilizers, feed or to prepare glycerin and biodiesel. However, these technologies are still immature and reliable, and the scope of application is not wide enough. Moreover, the treatment cycle is long and the investment is large, so t...
