Abstract
The invention provides a kind of method that Microwave Pretreatment strengthens sludge composting conditioner water imbibition, comprise the following steps that：Wooden raw material are processed into the square conditioner that particle diameter is the same particle size of 1 3cm, same shape；Conditioner is put into water and is soaked, the 6h of soak time 2；Conditioner is then taken out, surface is wiped and is attached moisture, put it into microwave reactor and heat；Conditioner and excess sludge after Microwave Pretreatment is applied in compost in 1: 3 ratio, its water absorbing properties is observed.The present invention is simple using equipment needed for Microwave Pretreatment conditioner, technique is easy, effectively increase conditioner itself space, improve the water absorption rate of conditioner, and then accelerate conditioner recycle process, be applied to be had very important significance in composting process through the conditioner of Microwave Pretreatment.
Description
Technical field
The present invention relates to sewage treatment plant residual Sewage Sludge in Composting processing technology field, specifically a kind of microwave is pre-
The method for the treatment of enhancing sludge composting conditioner water imbibition.
Background technology
Conditioner can play regulation material C/N ratios, moisture content and aeration etc. during Sewage Sludge in Composting
Function, is the important auxiliary material during sludge composting.Traditional conditioner mainly has stalk, rice husk, leaf and wood chip etc., above-mentioned
Effect of the conditioner in terms of Reactor structure is improved be not obvious, and dosage is big, it is difficult to recycle, and self component is fiber
The hard-degraded substances such as element, hemicellulose, lignin, mainly slowly degrade in the compost later stage, extend the sludge composting cycle, so that
Increased sludge composting cost.The present invention is that, in Publication No. CN102515904A, granted patent number is
ZL201110435933X, invention and created name is " a kind of recyclable degradation particles conditioner and its answering in sludge composting
With " on the basis of carry out, selected conditioner both has certain mechanical strength, auto-degradation speed again slowly,
And its water absorbing properties is significantly improved by Microwave Pretreatment.
During Sewage Sludge in Composting, the decomposition of organic matter and the growth and breeding of microorganism are required for necessarily in material
Moisture, compost material ideal moisture content be 55%~60%.And moisture percentage in sewage sludge is about 80%, a weight of conditioner is added
Act on be conditioning of mud moisture content.The present invention greatly strengthen the water absorbing properties of conditioner, allow conditioner quick
Absorb the moisture in sludge, so make mixed material moisture be rapidly achieved compost needed for ideal range (60% is left
It is right), shorten the sludge composting cycle.
The characteristics of present invention comes from interior of articles according to heating using microwave its thermal source, using heating using microwave conditioner, internal water
Outwards effusion increases conditioner itself space point to be changed into water vapour, and then improves the water absorbing properties of conditioner, when conditioner with
When sludge mixes, accelerate conditioner and moisture is absorbed from sludge, mixed material moisture is rapidly achieved compost ideal aqueous
Rate (55%~60%).
The content of the invention
In order to overcome existing conditioner water suction slow not enough, it is an object of the invention to pre- using a kind of new conditioner
Processing method, i.e., using heating using microwave conditioner, internal moisture is changed into water vapour, and outwards effusion increases conditioner itself space,
And then improve the water absorbing properties of conditioner.
The object of the present invention is achieved like this：
A kind of method that Microwave Pretreatment strengthens sludge composting conditioner water imbibition, comprises the following steps that：
(1) wooden raw material are processed into the square conditioner that particle diameter is the same particle size of 1-3cm, same shape；
(2) conditioner is put into water and is soaked, soak time 2-6h；
(3) conditioner is then taken out, surface is wiped and is attached moisture, put it into microwave reactor and heat；
(4) conditioner and excess sludge after Microwave Pretreatment are applied in compost in 1: 3 ratio, observe its water suction
Performance, observing interval is 12-24h.
The method that above-mentioned use Microwave Pretreatment strengthens sludge composting conditioner water imbibition, it is characterised in that：Microwave power
200-500W, microwave time 2-6min.
Positive beneficial effect：Compared with the conditioner without Microwave Pretreatment, (1) heating using microwave conditioner, internal moisture
Outwards effusion increases conditioner itself space to be changed into water vapour, for the water imbibition for strengthening conditioner is laid a good foundation；(2) microwave
Pretreated conditioner soaking effect is significantly improved.The present invention is using equipment letter needed for Microwave Pretreatment conditioner
Single, technique is easy, effectively increases conditioner itself space, improves the water absorption rate of conditioner, and then accelerate conditioner
Recycle process, be applied to that there is in composting process far-reaching social effect and economic valency through the conditioner of Microwave Pretreatment
Value.
Brief description of the drawings
Fig. 1 is the conditioner soaking effect figure after Microwave Pretreatment of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is described further：
A kind of method that Microwave Pretreatment strengthens sludge composting conditioner water imbibition, comprises the following steps that：
(1) wooden raw material are processed into the square conditioner that particle diameter is the same particle size of 1-3cm, same shape；
(2) conditioner is put into water and is soaked, soak time 2-6h；
(3) conditioner is then taken out, surface is wiped and is attached moisture, put it into microwave reactor and heat；
(4) conditioner and excess sludge after Microwave Pretreatment are applied in compost in 1: 3 ratio, observe its water suction
Performance, observing interval is 12-24h.
The method that above-mentioned use Microwave Pretreatment strengthens sludge composting conditioner water imbibition, it is characterised in that：Microwave power
200-500W, microwave time 2-6min.
