Embodiment Construction

[0030] The present invention will be described in detail below, and the objectives and effects of the present invention will become apparent from the

[0031] This example is taken as an example of processing 500 g of waste. Kitchen waste (vegetable leaves, etc.) and cooked rice, cooking leaves to <2cm. Refer to the actual kitchen trash, salt content to add oil and salt. A portion of rice straw is partially air drying with a grinder into a powder, partially cut into debris to 1-3 cm.

[0032] (1) Add 125g straw debris and 125g straw powder to each 250 g of cooking leaves and rice (rice: cooking leaves = 1: 1) as the treatment group, CK group is in a 250 g of vegetable leaves and rice (rice: vegetable leaf) = 1: 1) Add 250 g of straw powder, add 350 mL of deionized water, mix uniform and rot, each treatment, three repetitions, during the period;

[0033] (2) When the temperature of the matrix is ​​reduced to 20-25 ° C, it is placed in 20 daemons without the obvious loop (ar...

Abstract

The invention discloses a composting method suitable for earthworm treatment of high-oil and high-salt kitchen garbage, which comprises the following steps: step 1, adding a proper amount of straw powder and straw chippings into the high-oil and high-salt kitchen garbage, fully and uniformly mixing, and composting as a substrate; wherein the mass ratio of the high-oil high-salt kitchen garbage to the straw powder to the straw chippings is 2: 1: 1; 2, after the decomposition temperature of the substrate is reduced to 20-25 DEG C, earthworms are added, and 20 earthworms are added into every 500 g of the substrate; 3, the temperature of the substrate is kept at 20-25 DEG C for composting, regular observation is carried out, if the amount of earthworms in the composting process is reduced, supplementation is carried out till composting is completed, and the organic fertilizer is obtained. According to the method, straw powder and chippings are matched, so that oil and salt in the kitchen waste can be adsorbed, the filling power of the matrix can be improved, conditions more suitable for breathing and survival are provided for earthworms, the survival rate of the earthworms in the kitchen waste is guaranteed, and resource utilization of the waste is promoted.

Description

Technical field [0001] The present invention relates to the field of resource utilization, and more particularly to a composting method suitable for treating high oil high salt kitchen waste. Background technique [0002] The kitchen garbage is one of the most common garbage. It is generally derived from the catering industry, school, factory, company restaurant, etc., which is the main feature of salt, high oil content, difficult. The nutritional value of kitchen waste is high, and it is also in line with the concept of sustainable development, which is important for improving environmental pollution and development of circulating economy. [0003] At present, there are several treatment methods such as burning method, landfill, mechanical crushing method, feedification, anaerobic digestion, and composting treatment. The kitchen garbage compost is an efficient and environmentally friendly technology that can convert organic waste to stable, mature compost. The advantage is that ...
