Kitchen garbage composting conditioner and kitchen garbage treatment method

Abstract

The invention discloses a kitchen garbage composting conditioner and a kitchen garbage treatment method. The kitchen garbage composting conditioner comprises 79-92 parts of a thoroughly decomposed substrate, 1-3 parts of magnesium sulfate, 2-4 parts of calcium superphosphate, 5-9 parts of a desulfurized gypsum powder and 5-15 parts of a neutral and / or alkaline pH regulator, wherein the thoroughly decomposed substrate is obtained by mixing spent bleaching clay, agricultural and forestry wastes, a composite microbial inoculum and a surfactant according to a weight ratio of (55-90): (67-90): (0.01-0.25): (0.01-0.05), composting and fermenting; the composite microbial inoculum is formed through the combination of bacillus coagulans and bacillus subtilis according to a mass ratio of 0.6-0.8: 1. When the composting conditioner is applied to kitchen garbage composting treatment, the situation that odor is produced during the kitchen garbage composting treatment can be significantly improved, the composting speed rate is increased, and the compost quality is improved; a compost product is suitable for being used as an organic fertilizer or a soil improver, so that resource recycling is achieved.

Description

technical field [0001] The invention relates to the direction of waste resource utilization in the environmental field, in particular to a kitchen waste treatment method and a compost conditioner. Background technique [0002] Food waste is the main component of municipal solid waste. With the development of the catering industry, people choose more and more fine ingredients, and the total amount of food waste has continued to grow. At present, the main treatment methods of food waste include direct landfill and other primary treatment methods, and composting fermentation and other secondary utilization methods that are transformed into renewable resources. Since food waste is rich in nutrition, low in ash, and has a high moisture content, direct landfilling of a large amount of food waste will usually affect the stability of the landfill, cause certain safety hazards, and cause a waste of resources. Composting food waste is currently a highly recommended treatment method....

Problems solved by technology

This patent does not think that waste white clay is suitable for food residue treatment, but in fact, the inventors of the present application have proved that it is not practical to directly mix waste white clay with fermentation raw materials with high food residue oil content for fermentation treatment. White clay has also been found to delay the composting process and compost quality, which may be due to the hydrophobic structure of oil in waste white clay forming a local anaerobic environment, resulting in the inability of aerobic microorganisms to obtain sufficient nutrients, affecting the composting process and compost quality

Although the method of using polysaccharide decomposing enzymes to assist in the fermentation of food residues described in the aforementioned patent is feasible, the cost is relatively high, and the resource utilization of waste clay cannot be realized.
