Embodiment 1

[0030]1. Sludge collection: Sludge produced by urban sewage treatment plants with a water content of 75-85% is used as raw material.

[0031] 2. Collect fresh, non-deteriorated sugar factory filter mud as raw material.

[0032] 3. Collect strains: Collect the Hongshengyuan brand microbial fermentation agent produced by Guangxi Hongshengyuan Environmental Protection Technology Co., Ltd. as the strain, and expand the strain into a stock solution with a viable count of not less than 100 million / ml. Moreover, the pH of the strain stock solution is not less than 6.5, the color is a translucent yellow-brown liquid, and the smell is relatively strong sour.

[0033] The specific implementation is as follows:

[0034] (1) Raw material ratio: sludge 59.9%, sugar factory filter mud 40%, biological strain 0.1%;

[0035] (2) Fermentation: Premix the above sludge and sugar factory filter mud first, then add biological strains to mix and stir evenly, then pile up the mixed material and car...

Abstract

The invention provides a method for preparing solid-state bioorganic fertilizer by taking sludge as a raw material. The method specifically comprises the following steps: by taking sludge generated in a municipal sewage plant and lime sludge in a sugar refinery as raw materials, Hongshengyuan microbial fermentation inoculant, produced in Guangxi hong sheng yuan Environmental Protection Science co LTD., as a inoculant source, fermenting the sludge and lime sludge in the sugar refinery into a solid-state bioorganic fertilizer. Through the implementation of the method, the sludge generated in the municipal sewage plant and lime sludge in the sugar refinery are converted into a bioorganic fertilizer which is harmless, odorless, good in fertilizer effect and low in cost. Through the implementation of the method, organic matters can be comprehensively utilized so as to turn harm into good, and the purposes of turning harm into good, recycling and protecting the environment can be realized by taking the sludge and lime sludge as recycling biological resources. The sludge and lime sludge are recyclable resources, and certain economic benefits can be created on the basis of solving the environmental impact problem by taking the sludge and lime sludge as a resource for recycling.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for preparing solid bio-organic fertilizer from sludge. Background technique [0002] In order to improve the current situation of serious water pollution in my country, the problem of urban sewage treatment in my country has been given full attention during the "Ninth Five-Year Plan" period, and urban sewage treatment projects have developed rapidly. In recent years, with the rapid improvement of urban sewage treatment capacity, the amount of sludge has also increased significantly. Due to the extremely complex composition of sludge, the continuous output of sludge every day cannot be digested in time, and a large amount of untreated sludge is randomly piled up. , It is easy to cause new secondary pollution to the environment, so the resource utilization of sludge is an urgent problem to be solved in the current urban pollution control. [0003] The sludge prod...
