Abstract
The invention particularly relates to a silt/sludge solidifying agent and application thereof.The silt/sludge solidifying agent is characterized by being mainly prepared by mixing, by mass, 60-75% of nano-micron modified binding material, 5-10% of poly-aluminum-ferric silicate, 10-20% of zeolite powder or bentonite and 5-15% of quicklime.Paving construction of road filling can be performed by adding the silt/sludge solidifying agent accounting for 10-20% of total amount of silt/sludge into the silt/sludge, mixing and stirring in a stirrer for 10-30 min and placing under sunlight for sufficient irradiation and solidification after stirring is finished.The silt/sludge solidifying agent can lower water content of high-water-content silt/sludge, is high in solidifying strength and capable of effectively solidifying heavy metals in the silt/sludge and reaches requirements of filling and building earth filling.
Description
Technical field:
This relates to a kind of silt/sludge solidifying agent and application thereof.
Background technology:
Numerous for river course, inland city lake, the bottom has substantial amounts of mud to pile up.And to the collection of mud with process past
Big toward quantities, cost is surprising.Such as in South-to-North Water Transfer Project, the land expropriation cost of the dredging silt of generation is just
Up to 6.4 hundred million yuan.And these mud moisture content stacked are high, intensity is low, possibly together with toxic chemical substance, cause of disease
Biology waits some harmful components.External many developed countries manufacture the business such as high-efficient purification fuel, construction material with mud
Mode carries out comprehensive development and utilization to mud.But at home, due to technology and funds, the lake training of channel
Mud most or as filling material, reduce the moisture content of mud, improve the intensity of mud and meet the earthwork and fill
Requirement.Therefore, the inorganic material of domestic commonly used cement class carries out solidification process to mud, but cement class material
Material is when silt consolidation, and addition is relatively big, and poor to the solidification effect of High water cut mud.
CN105367009A discloses a kind of sludge curing agent and its preparation method and application, and mass parts pressed by this curing agent
The component of number meter consists of: cement 9～18 parts, lime 2～5 parts, gypsum 2～5 parts, bentonite 2～5 parts, causticity
Sodium 0.4～1 part.After said components being dried 6～8 hours in drying oven, after grinding, it is uniformly mixing to obtain curing agent.
But this invention is longer for hardening time, to high-moisture percentage sludge solidification DeGrain.
Accordingly, it would be desirable to a kind of silt/sludge curing material of a kind of high efficiency, low cost.
Summary of the invention:
In order to solve technical problem in existing sludge solidification material, for silt from the bottom of lake contains substantial amounts of organic matter and weight
The characteristics such as metal, silt/sludge solidifying agent that the invention provides a kind of excellent performance and application thereof, enters High water cut mud
The materials such as row solidification processes, and effectively reduces the moisture content of mud, the heavy metal in curing sludge, and improve mud
Intensity, reaches the requirement that the earthwork is filled.
The technical scheme is that
A kind of silt/sludge solidifying agent, by percentage to the quality, it is characterised in that mainly comprise for: micron modification of receiving is gelled
Material 60%-75%, polymeric aluminium ferrum silicate 5%-10%, zeolite powder is or/and bentonite 10%-20%, quick lime 5%-15%
Mix.
Each component is based on percent mass, and a described micron modified adhesive gel material of receiving obtains according to the following steps: (1) will
Activity SiO225%-40%, activity Al2O35%-10%, activity CaO 40%-50%, active Fe2O35%-10%,
Activity MgO 3%-5% is blended in 1450 DEG C of stoves calcining and obtains sinter in 20 minutes；(2) sinter that will obtain
With CaSO4Mix in 1:0.05:0.02 ratio with nano silicon, levigate to D95≤15 μm, obtain institute
That states receives a micron modified adhesive gel material.
Described zeolite powder is or/and bentonitic fineness is 400 mesh.
The purposes of the silt/sludge solidifying agent described in utilization, it is characterised in that: add in silt/mud and account for silt/mud total amount
The silt/sludge solidifying agent of 10%-20%, stir in stirrer for mixing, stir 10-30 minute, stir after terminating,
Put into irradiation completion of cure under sunlight, the making construction of road filler can be carried out.
Silt/the sludge solidifying agent of the present invention can reduce the moisture content of high-moisture percentage silt/mud, and solidification intensity is high, and can have
Heavy metal in the solidification silt/mud of effect, reaches landfill and builds the requirement banketed.
Detailed description of the invention:
In conjunction with example, the present invention is described further.
By activity SiO230%, activity Al2O310%, activity CaO 50%, active Fe2O35%, activity MgO 5%
It is blended in stove calcining and obtains sinter in 20 minutes；
By the sinter obtained and CaSO4Mix in 1:0.05:0.02 ratio with nano silicon, levigate
To D95≤15 μm, obtain receiving a micron modified adhesive gel material.
The each embodiment of table 1 is raw materials used and proportioning unit %
Table 2. is the result that the embodiment 1～7 as shown in table 1 is raw materials used and silt from the bottom of lake dehydrating and curing is processed by proportioning.
The table 2 dehydrating and curing treatment effect to mud
