Benefits of technology

This patented technology helps break down harmful chemical substances from contaminated areas by breaking them up into small particles that are then filtered out without leaving any remaining material behind on top or inside walls made with ceramic materials like porcelain tiles.

Problems solved by technology

This patented technical problem addressed by this patents relates to treating contaminated soil with nitrosophenol blue liquid that contains triphenylmethane called trinaphthoquinone or 2-(N-2'-dimethoxy-4',6' dimercaptan). These chemical substances are harmful environmental hazards because they cause damage when released into our environment during various stages of production process. Current methods for disposal involve burning them away at landfill sites after use, but these techniques may be expensive due to their high energy usage and costs associated therewith.

Embodiment 1

[0014] Mix perlite, fly ash and diatomaceous earth in proportion (60%, 37%, 3%), grind and mix with a ball mill to make sintering additives. Add 1% sintering binder to the mixture of TNT red water polluted soil and clay (mass ratio 7:3) and mix evenly. Sintered bricks were successfully fired at a sintering temperature of 1070°C.

Embodiment 2

[0016] Mix perlite, fly ash and diatomaceous earth in proportion (57%, 40%, 3%), grind and mix with a ball mill to make sintering additives. 5% sintering binder was added to the mixture of TNT red water polluted soil and clay (mass ratio 6:4) and mixed evenly. The sintered bricks were successfully fired at a sintering temperature of 1055°C.

Embodiment 3

[0018] Vermiculite, fly ash and diatomaceous earth are mixed in proportion (50%, 45%, 5%), ground and mixed with a ball mill to make a sintering additive. 5% sintering binder was added to the mixture of TNT red water polluted soil and clay (mass ratio 5:5) and mixed evenly. Sintered bricks were successfully fired at a sintering temperature of 1000°C.

Abstract

The invention relates to a sintering bonding agent for treatment of TNT red water polluted soil and a preparation method of the sintering bonding agent and belongs to the field of environmental protection. The sintering bonding agent for treatment of TNT red water polluted soil is prepared from perlite (or vermiculite), fly ash and diatomite and particularly prepared from, in percentage by mass, 55%-60% of perlite, 35%-40% of fly ash and 3%-8% of diatomite (or 50%-55% of vermiculite, 40%-45% of fly ash and 3%-8% of diatomite). The sintering bonding agent is applied to treatment of the TNT redwater polluted soil and can reduce energy consumption for sintering of sintered bricks, and sintering flue gas pollutants are discharged to the standard; particular pollutant, namely, sodium dinitrotoluene sulfonate, in soil is thoroughly decomposed and is not left in the sintered bricks; the strength of the sintered bricks meets the national standard of sintered clay bricks and is improved to some extent.
