Problems solved by technology

[0002] Sewage plant sludge refers to the flocs produced in the process of water treatment, which contains a lot of water, rich organic matter and nutrients such as N, P, K, etc. It also contains harmful substances such as heavy metals and pathogenic bacteria. If it is discharged arbitrarily without treatment, it will not only pollute the environment, but also be a serious waste of resources.

Abstract

The invention relates to a preparation method of an organic fertilizer raw material. The preparation method comprises the following steps: spreading sewage sludge on the ground with the thickness of 15-20cm, spraying a deodorant diluent and an EM diluent A, and carrying out rotary tillage; when the water content in sludge declines from 85-90% to 50-60%, stacking up sludge by a loader to perform fermentation, and when the temperature is reduced to 60-65 DEG C, overturning the sludge stacks by an overturning machine so that sludge inside the sludge stacks and air are mixed, wherein the water content is reduced to 32-37wt% after the sludge is biologically decomposed and fermented by EM; further spreading the fermented sludge, carrying out rotary tillage and airing for 3 days till the water content of the sludge declines to 18-20%, and crushing to obtain an auxiliary material; and uniformly mixing the obtained auxiliary material and the to-be-treated sludge and spraying the deodorant diluent and the EM diluent A for fermentation to obtain the organic fertilizer raw material. The treated sewage sludge is soft in texture and good in air permeability, meets the fertilizer preparation standard, and can be used for landscaping, planting of flowers and plants, soil improvement and the like.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a method for preparing organic fertilizer raw materials. Background technique [0002] Sewage plant sludge refers to the flocs produced in the process of water treatment. It contains a large amount of water, rich organic matter and nutrients such as N, P, and K. It also contains harmful substances such as heavy metals and pathogenic bacteria. If it is discharged arbitrarily without treatment , not only pollute the environment, but also a serious waste of resources. According to incomplete statistics, the national sewage discharge is 4474×10 7 m 3 / d , there are more than 100 sewage treatment plants of different scales and degrees of treatment. The amount of sludge generated every day is about 5%-10% of the sewage treatment volume. If these sludges are still treated by traditional disposal methods (such as landfill, incineration and ocean discharge, etc.), compared with today's strict...
