Description
Technical field
The present invention relates to field of sludge treatment, specifically a kind of municipal sludge processes firming agent and preparation method thereof.
Background technology
Municipal sludge complicated component, containing a large amount of microorganisms, pathogen, heavy metal and organic pollution etc..Along with the development of global economy and the movable increase of improving earth geographical environment, the workload of the dredging operation of city water channel is increasing.Due to reasons such as these mud or sludge granules is little, not easily dehydration, low bearing capacity, content of organics are high, mobility is big, it is impossible to the engineering being directly used as in reclamation, dyke building, road engineering is banketed.Mud is carried out, by solidification technology, a series of difficult problems that the utilization of resources becomes earth working material or the preprocessing means as landfill stabilization can solve the problem that in Treatment of Sludge.Exploitation highly effective sludge firming agent is the key of this processing procedure.
Domestic and international Normal practice is to add the inserts such as substantial amounts of sand in Sludge landfill process, but do so not only makes Sludge landfill cost be greatly increased, and also reduces the effective rate of utilization of landfill yard simultaneously.For the cured of mud, mud, current commonly used cement, Calx etc. are as firming agent.It is slow that ordinary cement, Calx condense hardening, and they will appear from the forward part sedimentation not condensed in high water-solid ratio situation, and mud organic substance content is high, can hinder the hydration reaction of cement, and solidification effect is poor, even cannot be carried out.
Summary of the invention
It is an object of the invention to provide a kind of municipal sludge and process firming agent and preparation method thereof, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of municipal sludge processes firming agent, it is prepared from by the raw material of following weight portion: 30～36 parts of Gypsum Fibrosum, crude salt 24～30 parts, bauxite 21～25 parts, plant ash 27～29 parts, sodium carboxymethyl cellulose 19～21 parts, silicon dioxide 9～13 parts, 8～10 parts of ferrous sulfate, sodium lignin sulfonate 7～9 parts, sepiolite powder 23～25 parts, triethanolamine 5～7 parts, soda 21～23 parts.
The preparation method that a kind of described municipal sludge processes firming agent, concrete preparation process is as follows:
(1) above-mentioned each raw material is taken by proportioning, standby；
(2) at ambient temperature, being mixed by above-mentioned each raw material, add the water of raw material 4～6 times, heating, to 110～120 DEG C, stirs 3～4h；
(3) it is cooled to room temperature, dry 6～7h at the temperature of 65～67 DEG C, and to be ground to particle diameter be 240～300 orders,.
Compared with prior art, the invention has the beneficial effects as follows: firming agent of the present invention has the advantage that penetration is strong, speed is fast, dosing is few, and solidification effect is good, ensure that later strength will not reduce simultaneously；Mud stink can be removed；Reduce heavy metal to the release in environment.
