Description

A kind of municipal sludge processing curing agent and preparation method thereof
The application is application number 2016100628838, the applying date 2016 year 01 month 30, " a kind of city is dirty for denomination of invention The divisional application of mud processing curing agent and preparation method thereof ".
Technical field
The present invention relates to sludge treatment field, specifically a kind of municipal sludge processing curing agent and preparation method thereof.
Background technology
Municipal sludge complicated component, contains a large amount of microorganisms, pathogen, heavy metal and organic pollution etc..With the whole world Expanding economy and the increase of improving earth geographical environment activity, the workload of the dredging operation of city water channel are increasing.By In these sludge or sludge granules it is small, be difficult dehydration, low bearing capacity, the reason such as content of organics is high, mobility is big, it is impossible to directly Banketed as the engineering in reclamation, dyke building, road engineering.Sludge is subjected to the utilization of resources by solidification technology A series of problems in Treatment of Sludge are can solve the problem that as earth working material or as the preprocessing means of landfill stabilization.Exploitation is efficient Sludge solidifying agent is the key of the processing procedure.
Domestic and international Normal practice is that the inserts such as substantial amounts of sand are added during Sludge landfill, but such do not only makes Sludge landfill cost is greatly increased, while also reducing the effective rate of utilization of landfill yard.For the curing process of sludge, mud, mesh It is preceding that curing agent is generally used as using cement, lime etc..Ordinary cement, lime condense hardening slowly, and they are in the case of high water-solid ratio Non-condensing forward part sedimentation is will appear from, and mud organic substance content is high, can hinder the hydration reaction of cement, solidification effect is poor, It can not even carry out.
The content of the invention
It is an object of the invention to provide a kind of municipal sludge processing curing agent and preparation method thereof, to solve above-mentioned background The problem of being proposed in technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of municipal sludge handles curing agent, is prepared from by the raw material of following parts by weight：30~36 parts of gypsum, crude salt 24 ~30 parts, 21~25 parts of bauxite, 27~29 parts of plant ash, 19~21 parts of sodium carboxymethylcellulose, 9~13 parts of silica, 8~10 parts of ferrous sulfate, 7~9 parts of sodium lignin sulfonate, 23~25 parts of sepiolite powder, 5~7 parts of triethanolamine, soda ash 21~23 Part.
A kind of described municipal sludge handles the preparation method of curing agent, and specific preparation process is as follows：
(1) above-mentioned each raw material is taken by proportioning, it is standby；
(2) at ambient temperature, above-mentioned each raw material is mixed, adds the water of 4~6 times of raw material, be heated to 110~120 DEG C, Stir 3~4h；
(3) room temperature is cooled to, 6~7h is dried at a temperature of 65~67 DEG C, and is ground to particle diameter for 240~300 mesh, i.e., Can.
Compared with prior art, the beneficial effects of the invention are as follows：Curing agent of the present invention has that penetration is strong, speed fast, medicine The few advantage of agent consumption, solidification effect is good, while ensureing that later strength will not be reduced；It can remove sludge stink；Reduce heavy metal Release into environment.
