Description
Technical field
The present invention relates to feces of livestock and poultry desiccation dewater treatment technical field, and in particular to medicine is nursed one's health in a kind of feces of livestock and poultry desiccation
Agent and desiccation dewatering process.
Background technology
With the increase of the rapid development of economy, the continuous growth of population, meat product and its byproduct demand, fowl animal husbandry
Constantly development, cultivation scale also constantly expands, while generates substantial amounts of fowl and animal excrement, according to conservative statistics, to the year two thousand twenty,
China's livestock culture will produce 4,100,000,000 tons of fowl and animal excrements every year, if these excrement are dealt with improperly, it will brought seriously to environment
Harm, conversely, if it is possible to effective processing, can also turn waste into wealth, carry out recycling, create huge economic effect
Benefit.
The moisture content of fowl and animal excrement is very high, and typically between 70-98%, it is fowl and animal excrement that fowl and animal excrement is made into organic fertilizer
The most common way of processing, originate compost optimum moisture content requirement control between 55-65%, to make Composting into
Work(, excrement water content is reduced to meet that compost needs are most important.
The method that fowl and animal excrement dehydration uses mainly has high temperature and rapid drying, biologically dehydrating and mechanical dehydration, mechanical dehydration
Energy consumption it is relatively low, the cycle is shorter, most widely used, and the effect of mechanical dehydration is relevant with the operational factor of plant equipment, poultry
Excrement will reach the effect of mechanical dehydration, it is necessary to first carry out modifier treatment to it, change the characteristic of excrement, improve dewatering.
The purpose of excrement conditioning is to allow moisture in excrement more to be converted to Free water or Interstitial Water, and conventional Opsonizing method has chemical tune
Reason, biology conditioning, physics conditioning and the class of co-conditioning four.In order to reach the aqueous requirement of Composting processing, research one
Cover effective fowl and animal excrement desiccation conditioning medicament and desiccation dewatering process and have become an important direction.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of feces of livestock and poultry desiccation to nurse one's health medicament and desiccation dewatering process,
The change of the medicament and technique to pH is small, and dehydrating effect is good, is advantageous to the compost of feces of livestock and poultry, burns recycling.
To realize goal of the invention, the present invention uses following technical scheme：
Medicament, including following components are nursed one's health in a kind of feces of livestock and poultry desiccation, by accounting for based on the percentage by weight of excrement oven-dry weight：
Oxalic acid 10-30%；
Polyferric silicate sulfate 3-10%；
Hydrogen peroxide 2-7%；
Chitosan 0.05-0.3%；
Wood chip 3-8%.
Preferably, including following components, by accounting for based on the percentage by weight of excrement oven-dry weight：
Oxalic acid 20%；
Polyferric silicate sulfate 7%；
Hydrogen peroxide 5%；
Chitosan 0.2%；
Wood chip 6%.
Preferably, the hydrogen peroxide can be replaced with strong oxidizer, and strong oxidizer includes chlorine dioxide, sodium hypochlorite.
A kind of feces of livestock and poultry desiccation dewatering process, is comprised the technical steps that：
A. nurse one's health：The solid content of feces of livestock and poultry is controlled between 2-4%, takes fowl and animal excrement to add in ultrasonic reaction container, ultrasound
Wave band is set to 20kHz-100kHz, adds oxalic acid and polyferric silicate sulfate, and pH is controlled between 5.5-6.5, stirring, controls rotating speed
200-400r/min, react 5-10min；Fowl and animal excrement after above-mentioned processing is added into hydrogen peroxide stirring, control rotating speed 200-
400r/min, react 10-20min；Above-mentioned feces of livestock and poultry is pumped into flocculation sedimentation tank, adds chitosan and wood chip, is stirred, control
Rotating speed 30-50r/min processed, react 1-5min；
B. press filtration：Fowl and animal excrement after above-mentioned conditioning is subjected to barrier film filter-press dehydration processing, pressure is set to 1.1 ~ 1.8MPa, presses
Squeeze 10 ~ 30min.
Preferably, filter cloth is monofilament twill nylon filtering cloth used by step b septations filter-press dehydration, and air permeability control exists
100-300×10-3M3/M2S, fowl and animal excrement content of organics is high, easily blocks and bonds filter cloth and cause filtrate not pass through
Filter cloth, using the filter cloth that air penetrability is larger, filter cloth blocking is not easily caused, be not in cohesive filter cloth, be not easy the phenomenon of de- cake.
The beneficial effects of the invention are as follows：
1st, the present invention is applied widely, and the fowl and animal excrement that can be directed to is that water rushes excrement technique, bubble excrement technique or dry cleaning up excrement work
One or more in pig manure that skill obtains, cow dung, sheep manure, rabbit excrement, chicken manure, duck excrement, goose excrement, pigeon dung, quail excrement, turkey excrement；
2nd, the present invention passes through ul-trasonic irradiation, shortening using physics conditioning and the co-conditioning mode of chemical conditioning composition
The reaction time required for conditioning is learned, improves operating efficiency；
3rd, chemical conditioning mode of the invention employs the synergy mechanism of flocculation and strong oxidation, improves sludge
Dewatering；
4th, oxalic acid and molysite of the invention act on forming complex compound, can prevent molysite from forming sediment in meta-alkalescence solution,
Reduce the utilization rate of molysite；
5th, hydrogen peroxide of the invention can be replaced with strong oxidizers such as chlorine dioxide, sodium hypochlorite, under the catalytic action of molysite,
Using the strong oxidation of oxidant, cell extracellular polymeric structure is cracked, then pass through the bridging effect of chitosan and wood chip
Skeleton function changes the property of sludge, improves dewatering；
6th, desiccation of the invention nurses one's health medicament based on organic matter, does not introduce chlorion and strong acid and strong base, the change to pH compared with
It is small, be advantageous to the compost of excrement, burn recycling；
7th, moisture content of the cake is below 60% after fowl and animal excrement of the invention is dehydrated.
