Problems solved by technology

[0002] A large amount of sludge is produced in the process of carrying out biological treatment of river sludge in my country. The sludge has high moisture content and high organic content. However, it will be directly used as soil backfill material after dehydration treatment, which will produce heavy metal polluted soil and cannot be used as fertilizer. crop

Embodiment Construction

[0011] The technological process of sludge dehydration and solidification microbial organic fertilizer treatment method of the present invention is as follows figure 1 As shown, the process is based on the cleaning of river sludge in the suburbs of Shanghai, adding microbial deodorizers to the sludge settling tank for deodorization, and then dehydrating with a mechanical dehydration device to realize the integrated treatment of sludge dehydration, deodorization and solidification , The dehydrated and solidified sludge is then added with microbial preparations to the dehydrated and solidified sludge solids, and after being fully stirred, it becomes a high-quality microbial organic fertilizer that turns waste into treasure. When fertilizing, the outdoor temperature should be above 20°C. The microbial activity is strong and has a great effect on crops. When it is lower than 20°C, the microbial activity is poor. Below 2°C, the microbial bacteria will be dormant. The biggest advanta...

Abstract

The invention discloses a novel method for deodorizing and dehydrating sludge into microbial organic bacterial manure. The novel method comprises the following steps: adding river channel mud to be treated or sludge obtained by concentrating oil refinery sewage into a sludge tank, adding a deodorizer for stirring and deodorizing, then conveying the sludge to a sludge filter press through a stainless steel filter screen belt, conveying the filtered sludge to a drying device, drying the sludge to obtain solid sludge with the water content below 10%, then adding a proportioned microbial agent capable of decomposing heavy metal ions, and executing full stirring and mixing. The microbial organic bacterial manure can be bagged after being treated by the method, serves as the microbial organic bacterial manure turning waste into wealth, is used as a crop fertilizer, improves the environment and plays a role in waste utilization.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a method for dehydrating and solidifying sludge into microbial organic fertilizer. Background technique [0002] A large amount of sludge is produced in the process of carrying out biological treatment of river sludge in my country. The sludge has high moisture content and high organic content. However, it will be directly used as soil backfill material after dehydration treatment, which will produce heavy metal polluted soil and cannot be used as fertilizer. crop. The method of the invention is to use the microbial preparation produced by the company to deodorize sludge and sewage and decompose heavy metal ions, so as to turn waste into wealth and provide a new type of high-efficiency microbial organic fertilizer for crops. Contents of the invention [0003] The purpose of the present invention is to provide a new method for the production of microbial org...
