Embodiment I

[0033] Fermentation treatment of 100 tons of domestic waste and sludge. After removing stones, plastics, glass and other sundries in the domestic waste, the weight ratio of the waste to the sludge is 4:6. The main components and content of domestic waste are: organic matter 35.58% , total nitrogen 0.4668%, total phosphorus 0.2091%, total potassium 0.9264%, moisture 57.7%, PH value 6.9; the main components and contents of sludge are: organic matter 52.2%; nitrogen 4.19%, phosphorus 0.28%, potassium 0.968%, water Part 75.35%, pH value 7.0.

[0034] Material pretreatment:

[0035] Due to the low nitrogen content in the garbage, the C / N ratio in the material mixed according to the stated ratio cannot reach the condition of 30 to 35: 1, so an appropriate amount of urea is added to the material to increase the nitrogen content of the material, and adjust the The C / N ratio in the material reaches the requirement of 30-35:1. The pH value of the material is adjusted to 6-7, and the m...

Embodiment II

[0058] Fermentation treatment of 100 tons of straw and sludge, the ratio of straw and sludge in terms of dry weight is 4:6, the main components and contents of straw are: moisture 5.5%, crude protein 5.7%, crude fat 1.6%, crude fiber 29.3% , 51.3% nitrogen-free extract, 6.6% crude ash, trace amounts of calcium and phosphorus, and PH value 6.5; the main components and contents of the sludge are: organic matter 52.2%, nitrogen 4.19%, phosphorus 0.28%, potassium 0.968%, moisture 75.35% , PH value 7.0.

[0059] Material pretreatment:

[0060] Adjust the PH value of the material to 6-7, the C / N ratio to 30-35:1, and the moisture content to 50-60%;

[0061] Preparation of organic material decomposed solid mixed microbial agent for the first fermentation: the required organic material decomposed bacteria, including Trichoderma viride, Aspergillus niger, Candida tropicalis, Bacillus subtilis and Pseudomonas fluorescens, etc., were cultured in test tubes , Different strains use their...

Abstract

The present invention is process of twice fermenting garbage-sludge mixture to produce microbial fertilizer. The production process can eliminate environment pollution caused garbage and sludge while providing environment friendly efficient microbial fertilizer. The produced microbial fertilizer has high fertility, beneficial bacteria content up to 10<8>-10<10> / g and various bioactive matters. The produced microbial fertilizer can promote the growth of crop, strengthen the disease resistance of crop and raise yield of crop.

Description

technical field [0001] The invention relates to a method of using garbage and sludge mixture as a raw material, inserting decomposed solid mixed bacterial agent of organic material for producing microbial bacterial fertilizer and mixed bacterial suspension of beneficial bacteria, and adopting a secondary fermentation process to produce microbial bacterial fertilizer. Background technique [0002] The "garbage" referred to in the present invention is a general designation of domestic garbage and organic waste in industrial and agricultural production processes. [0003] The "domestic garbage" referred to in the present invention refers to solid and semi-solid waste generated in daily life or in the activities of providing services for daily life, including various organic wastes such as waste food, feces, and waste paper. The "organic wastes in the process of industrial and agricultural production" referred to in the present invention refers to sawdust, straw, pomace, leftove...
