Embodiment 1

[0025] 1. Implementation steps

[0026] (1) Drain the accumulated water in the breeding pond, expose to the sun until it cracks, soak in water for 10 days, then drain it and expose it to the sun until it cracks, repeating this many times.

[0027] (2) Measure the Cl of the sample after air-drying respectively - Concentration, PH value, conductivity and other indicators;

[0028] (3) Rinse, drench, and elute salt from the dried mariculture sludge to make the water-to-soil mass ratio 5:1, stir at 25° C. for 8 minutes, filter, and air-dry.

[0029] (4) Collect the filtrate and measure the content of nitrogen and phosphorus. Determination of Cl in air-dried sludge after soaking - Concentration, PH value, conductivity and other indicators.

[0030] (5) Mix the air-dried mariculture sludge after soaking, sugar factory filter mud and peanut straw dry powder in a ratio of 4:3:2 (mass ratio). Add 2 kg of Bacillus subtilis species to the mixture for anaerobic fermentation, and dete...

Abstract

The invention relates to a method for producing micro organic matters by marine culture sludge and sugar refinery filtration sludge, belonging to the comprehensive utilization of marine animal utilization technology and sugar refinery filtration sludge drogs and being dedicated in preparing micro organic matter fertilizer by marine culture sludge and sugar refinery filtration sludge. The method comprises the following steps: wind drying the marine culture sludge and sugar refinery pond sludge and desalting by leaching the culture sludge; mixing the leached wind-dried sludge and the sugar refinery wind-dried pond sludge with fresh plant dry power, adding viable bacteria for anaerobic fermentation with the proportion of 2kg of viable bacteria per ton and the moisture is controlled at 30-35%, fermenting for about 10 days at the temperature of 50-60 DEG C, adding 4% of sodium humate, 7% of nitrogenous fertilizer, 12% of phosphate fertilizer and 6% of potassium fertilizer into composts after fermentation to obtain the halophilous plant highly efficient organic fertilizer. The water-soil proportion of the organic fertilizer is controlled at 5:1 to be proper, and the sum nutrient of N+P+K is more than or equal to 48%. The leaching, fermenting and composting technologies of the invention have simple and convenient process, strong operation, high production efficiency and high fertilizer effect with rich nutrient.

Description

【Technical field】 [0001] The invention relates to a method for producing microbial fertilizers from seawater aquaculture sludge and sugar factory filter mud, which belongs to the comprehensive utilization of marine organism utilization technology and sugar factory filter mud waste residue, and is specially used for preparing microbial organic fertilizers from seawater aquaculture sludge and sugar factory filter mud . 【Background technique】 [0002] The 21st century is the century of marine technology revolution for the development and comprehensive utilization of marine resources. Whoever seizes the peak of marine technology first, the economy can develop by leaps and bounds. At present, the supply of fish, shrimp and crab products in the world mainly depends on farming. However, the sludge at the bottom of the mariculture pond will produce a large amount of toxic substances, pathogenic bacteria and nutrients required for plant growth as time goes on. It is highly poisono...
