Example Embodiment
[0014] Example 1 Fermentation of domestic sewage sludge
[0015] After sampling the domestic sewage sludge, concentrating and dewatering with a belt filter press, the water content is about 75%. After analysis, the sludge contains a large amount of organic matter and N, P, K, etc. The analysis results are shown in Table 1. The domestic sewage sludge also contains some metal elements. The specific results are shown in Table 2.
[0016] Table 1
[0017] sample
[0018] Table 2
[0019]
[0020] It can be seen from the above table that the content of heavy metal elements in sewage sludge is far lower than the national agricultural standards, and can be used safely as fertilizer.
[0021] Fermentation of domestic sewage sludge: collecting domestic sewage sludge, manually sorting it, removing non-compostable components including stones, metal, glass and plastic, thickening and dewatering with belt filter press to a moisture content of 40%- 60%, crushed, and sieved; ferment the treated d...

Abstract
The invention relates to a base fertilizer compound fertilizer and application thereof, in particular to a mixed compound fertilizer utilizing domestic sludge and sewage and application of the mixed compound fertilizer and belongs to the technical field of bio-fertilizers. The base fertilizer compound fertilizer is prepared from waste soybeans, waste wheat, waste sorghum, waste corns, a nitrogen fertilizer, a phosphate fertilizer and fermented domestic sludge and sewage and is prepared by fully mixing the components. By adopting the base fertilizer compound fertilizer to apply the fertilizer to soils, the fertilizer application amount is 40-60 catty/mu. By adopting the base fertilizer compound fertilizer, the domestic sludge and sewage are fermented with high-temperature treatment, and worm eggs and pathogenic microorganisms can be killed, so that a finished product reaches harmlessness; and by being mixed and used by matching with the waste soybeans, the waste wheat, the waste sorghumand the waste corns, a fertilizer containing rich humus can be prepared, and the finished fertilizer is stable in fertilizer efficiency, is not rotted and does not smell bad.
Description
technical field [0001] The invention relates to a base fertilizer compound fertilizer and its application, in particular to a mixed compound fertilizer using domestic sludge sewage and its application, and belongs to the technical field of biological fertilizers. Background technique [0002] Sewage sludge is an inevitable product of urban sewage treatment plants. According to statistics, in 1997, the annual output of dry sludge in my country's urban centralized sewage treatment plants has reached 600,000 tons, and with the development of society and the continuous improvement of people's living standards, sewage The output of sludge will continue to increase, if the sludge is not properly disposed of, it will cause secondary pollution to the environment. On the other hand, sewage sludge contains rich organic matter, N, P, K and other beneficial components, which will cause waste of resources if not utilized. Therefore, the disposal and utilization of sewage sludge has arouse...
