CN103864478A - Process for producing fertilizer by using municipal sludge - Google Patents

Abstract

The invention provides a process for producing a fertilizer by using municipal sludge, wherein the fertilizer can be prepared by inoculating the following raw materials in parts by weight with a traditional Chinese medicine microbial agent: 40-60 parts of municipal sludge, 10-40 parts of river bottom sludge, 10-30 parts of pine bark chippings, 3-10 parts of hay meal, 3-10 parts of mushroom dreg and 0-10 parts of fly ash. The process is advantageous for environmental protection and also capable of greatly reducing the waste mud treatment cost.

Description

Utilize municipal sludge to produce the technique of fertilizer

Technical field

The invention belongs to biological fertilizer field, be specifically related to a kind of technique of utilizing municipal sludge to produce fertilizer.

Background technology

The processing of municipal sludge is wasted time and energy, and cost is huge equally, and the cost that peasant purchases biological organic fertilizer is also high, and this is just in the urgent need to a kind of method that both can be combined.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of technique of utilizing municipal sludge to produce fertilizer.

The technical solution adopted for the present invention to solve the technical problems is: the fertilizer that utilizes municipal sludge to produce, is prepared from by the raw material inoculation traditional Chinese medicine microbial agent of following weight proportioning: 40～60 parts of municipal sludges, 10～40 parts, river bed mud, 10～30 parts of Cortex Pini chips, 3～10 parts, hay powder, 3～10 parts of bacterium slags, 0～10 part, flyash.

The present invention also provides the technique of utilizing municipal sludge to produce fertilizer, comprises the steps:

A, culture material preparation: by weight ratio 0～10 part of 40～60 parts of municipal sludge, 10～40 parts, river bed mud, 10～30 parts of Cortex Pini chips, 3～10 parts, hay powder, 3～10 parts of bacterium slags, flyash is mixed and regulate mixture water content to 55～65%, obtain culture material;

B, inoculation: bacterium slag is inoculated in culture material, and bacterium slag and culture material are fully mixed;

C, fermentation: postvaccinal culture material ferment to the water content of culture material be 18～30%, the living microorganism content in culture material is more than 2,000 ten thousand/gram, gets product.

Embodiment

The present invention also provides the technique of utilizing municipal sludge to produce fertilizer, comprises the steps:

A, culture material preparation: by weight ratio 0～10 part of 40～60 parts of municipal sludge, 10～40 parts, river bed mud, 10～30 parts of Cortex Pini chips, 3～10 parts, hay powder, 3～10 parts of bacterium slags, flyash is mixed and regulate mixture water content to 55～65%, obtain culture material;

B, inoculation: Chinese medicine microbiobacterial agent bacterium slag is inoculated in culture material, and bacterium slag and culture material are fully mixed;

C, fermentation: postvaccinal culture material ferment to the water content of culture material be 18～30%, the living microorganism content in culture material is more than 2,000 ten thousand/gram, gets product.

This patent can be by refuse reclamation, environmental protection and reduction overall cost of operation.

Embodiment recited above is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under spiritual prerequisite not departing from the present invention; various distortion and improvement that the common engineering technical personnel in this area make technical solution of the present invention, all should fall in the definite protection domain of claims of the present invention.
