Abstract

The invention discloses a biomass-charcoal-containing composting system and composting method. The biomass-charcoal-containing composting system mainly comprises the following raw materials in parts by weight: 92-110 parts of basic composting material, 0.3-0.5 part of microbial inoculant and 0.9-1.8 parts of biomass charcoal. The basic composting material comprises sludge and straws, wherein the sludge and straws are mixed, so that the carbon-nitrogen ratio of the basic composting material is 20-30, and the water content of the basic composting material is 50-70%. The method comprises the following steps: mixing the raw materials for constituting the basic composting material, adding the microbial inoculant and biomass charcoal into the basic composting material, and uniformly mixing to obtain the composting system. A three-step fermentation process is utilized to perform composting fermentation on the composting system for 28-32 days, thereby obtaining the biological compost.

Description

technical field

[0001] The invention relates to the technical field of biological composting, more specifically, the invention relates to a composting system containing biochar and a composting method thereof. Background technique

[0002] With the improvement of the urban sewage treatment rate in our country, a large amount of sludge is produced. If it is not treated effectively, it will easily cause secondary pollution to groundwater and soil. Compared with livestock and poultry manure, sludge has 2 to 3 times higher organic matter and higher nitrogen, phosphorus and potassium content. It is an excellent raw material for making organic fertilizers. Composting sludge will not only solve the pollution problem and turn waste into treasure, but also concentrate the volume of sludge in a large amount, reducing the pressure on sludge discharge sites and landfills caused by a large amount of sludge stacking. However, because sludge contains a large number of pathogenic microorga...
