Embodiment 1

[0031] The municipal solid waste compost is taken from Tianjin Dagang waste dump, and the waste compost has been fully decomposed. Then garbage composting removes wastes such as plastic films, fiber bags, larger pieces of various metals, glass products, bricks, tiles and stones, crushes them, mixes them evenly and sieves them, passes through a 2mm sieve to collect the underscreen, and uses them separately Seal the plastic bag and put a label on it for later use. The control loam was obtained from the South Campus of Tianjin Normal University, and the preparation method was the same as above.

[0032] The determination of saturated water holding capacity provides a basis for checking the ratio of compost to water in the composting of domestic waste. Weigh 10g of each garbage sample, put it into a funnel with filter paper, and then slowly and evenly drop it on the compost in the funnel with distilled water until the first drop of solution drops in the funnel, and collect the so...

Abstract

This invention relates to a method for manufacturing washing solution from domestic waste compost. The method comprises: (1) pulverizing domestic waste compost, sieving with a 2 mm sieve, and collecting the powder; (2) mixing with water at a wt. ratio of 1 :( 1-3), stirring, soaking at room temperature for 24-48 h, and filtering to obtain the final product. The washing solution can be used as the nutrition solution for sod soilless culture. The method can reduce the pollution caused by heavy metals in domestic waste compost, and lower the cost of sod soilless culture.

Description

technical field [0001] The invention relates to the treatment and application of urban domestic garbage composting, in particular to a municipal domestic garbage composting eluent and its preparation method and application. [0002] The technical field where heavy metal restoration intersects with lawn establishment. The application of technological inventions not only plays a role in remediating heavy metal pollution from domestic waste composting and realizing safe and effective utilization, but also can use compost eluent to cultivate carpet turf, save soil resources, and serve the purpose of urban greening. Background technique [0003] Since the 1990s, my country's municipal solid waste has grown at an annual rate of 8%-10%. According to the information provided by the Ministry of Science and Technology, the stock of urban garbage in the country has now reached 6 billion tons, resulting in the formation of a large number of garbage mountains around 2 / 3 of the cities in...
