Abstract
A kind of sludge carbon organic fertilizer production technique of the present invention, it is on the basis of deeply dehydrating sludge technology and sludge carbonization technology, sludge dewatering decrement is become into dewatered sludge (being divided into two class of wet mud and dehydrated sludge cake), dewatered sludge is divided into two parts, sludge carbon is made in a part of dewatered sludge charing, is then stirred the technique that sludge carbon organic fertilizer is made with another part dewatered sludge again.
Description
Technical field
The present invention relates to Sludge Composting technical fields, are related specifically to a kind of sludge carbon organic fertilizer production technique.
Background technique
There are many sludge type, have the excess sludge mud from 99% or more sewage disposal system moisture content, there is excess sludge
Mud generates the wet mud of moisture content 80% or so through mechanical dehydration, there is the moisture content 60% generated through high pressure board and frame machine filter-press dehydration
Left and right dehydrated sludge cake contains many organic matters in sludge, and the fertilizer efficiency of plant growth is conducive to comprising nitrogen, phosphorus, potassium etc., and Sludge Composting passes
Technique of uniting is realized by composting process, and the common compost of auxiliary material is added in sludge, makes fertile process cycle field, needs to occupy a large amount of
Place, generation stink etc., after adding auxiliary material, the weight of fertilizer of generation is greater than original sludge quantity, as product dull sale causes to produce
Product are overstock, it is easy to cause Sludge Composting that cannot continuously run well.Sludge Composting technique of the present invention has obviously than composting process
Advantage, 1. mud decrement is obvious；2. plant area's occupied area is small；3. the Sludge Composting period is short；4. fertilizer efficiency is good, moisture content is low,
Product is stablized.
Summary of the invention
A kind of sludge carbon organic fertilizer production technique of the present invention, is in deeply dehydrating sludge technology and sludge carbonization skill
On the basis of art, sludge dewatering decrement is become into dewatered sludge (being divided into two class of wet mud and dehydrated sludge cake), dewatered sludge is divided into
Two parts, a part of dewatered sludge charing are made sludge carbon, are then stirred again with another part dewatered sludge and sludge is made
The technique of charcoal organic fertilizer；Sludge carbon organic fertilizer production technique is divided into two kinds, and one kind is that sludge carbon mixes the fertile technique of system with wet mud,
One kind is that sludge carbon mixes the fertile technique of system with dehydrated sludge cake；It is that wet mud is divided into two that sludge carbon, which mixes the fertile technique of system with wet mud,
Part, a part enter deep dehydration system for sludge and dehydrated sludge cake are made, and then enter back into sludge drying carbonization system and dirt is made
Peat, sludge carbon enter back into sludge agitation hybrid system, are uniformly mixed according to a certain percentage with another part wet mud, dirt is made
Peat organic fertilizer；It is that wet mud or excess sludge mud are entered sludge deep to take off that sludge carbon, which mixes the fertile technique of system with sludge cake,
Dehydrated sludge cake is made in water system dehydration, dehydrated sludge cake is divided into two parts, a part, which enters sludge, dries carbonization system system
At sludge carbon, sludge carbon enters back into sludge agitation hybrid system, is uniformly mixed according to a certain percentage with another part dehydrated sludge cake,
Sludge carbon organic fertilizer is made.
Detailed description of the invention
Fig. 1 sludge carbon mixes the fertile technique of system with wet mud, and Fig. 2 sludge carbon mixes the fertile technique of system with dehydrated sludge cake.
Specific embodiment
Embodiment 1

Dehydrated sludge cake is made, dehydrated sludge cake is divided into two parts, and a part enters sludge drying and dewatering system and sludge carbon is made, subsequently into
Sludge agitation hybrid system is uniformly mixed with the dehydrated sludge cake of another part and sludge carbon organic fertilizer is made.
Embodiment 2
A kind of sludge carbon organic fertilizer production technique specific embodiment wet mud enter deep dehydration system dehydration be made it is de-
Pat of cement, dehydrated sludge cake are divided into two parts, and a part enters sludge drying and dewatering system and sludge carbon is made, stirs subsequently into sludge
Hybrid system is mixed, is uniformly mixed with the dehydrated sludge cake of another part and sludge carbon organic fertilizer is made.
Embodiment 3
A kind of sludge carbon organic fertilizer production technique specific embodiment wet mud is divided into two parts, and a part enters deep dehydration
Dehydrated sludge cake is made in system dehydration, enters back into sludge drying and dewatering system and sludge carbon is made, mixed subsequently into sludge agitation
Collaboration system, is uniformly mixed with the wet mud of another part and sludge carbon organic fertilizer is made.
Above-mentioned case study on implementation does not represent the production of all devices series all, no longer illustrates one by one at this.
