Abstract

The invention discloses a sewage treatment plant sludge treatment method, an organic fertilizer and a preparation method of the organic fertilizer, and belongs to the technical field of sludge recycling. The method is technically characterized by comprising the following steps: S1, pouring 15-25 parts of edible fungus residues into a fermentation container, and fermenting for 45 days or more at aconstant temperature; S2, taking out the fermented edible fungus residues, adding the taken-out edible fungus residues into 35-45 parts of sludge, adding 0.1-0.3 part of a deodorant, performing uniform stirring, pouring the materials into the fermentation container, and performing constant-temperature fermentation at normal temperature for 15-20 days; and S3, adding 3-6 parts of tobacco into the fermentation container, and uniformly stirring to finish the sewage treatment plant sludge treatment. The method has the advantages that the sludge treatment cost is reduced, and the treated sludge canbe directly utilized.

Description

technical field [0001] The invention belongs to the technical field of sludge recovery and utilization, and more specifically, relates to a treatment method of sewage treatment plant sludge and a preparation method for use and use. Background technique [0002] With the development of industrialization and the acceleration of urbanization in our country, a large amount of industrial sludge and domestic sludge have been produced. This kind of sludge has a high moisture content and contains a large amount of pathogenic bacteria, parasite eggs, and heavy metals such as chromium and lead, which are poisonous and harmful. Substances are pollutants with complex properties, high pollutant content and huge potential environmental risks. The problem of sludge treatment has become a major environmental protection problem that needs to be solved urgently in today's society. [0003] In the Chinese invention patent with the publication number CN107285580B, a sludge treatment method is d...
