Description
Technical Field
The invention relates to the field of waste engineering mud treatment, in particular to a waste engineering mud soft consolidation body planting matrix.
Background
Engineering mud is the indispensable construction consumptive material of shield engineering for building engineering, bridge pile foundation engineering, underground tunnel, mainly divide into clay mud, bentonite mud and polymer mud three major types, and generally speaking, pile foundation engineering drilled pile mud quantity is 3 ~ 5 times of drilled pile volume, and the slurry shield mud yield is 2 ~ 3 times of tunnel excavation volume, and the construction is estimated to produce about dozens of ten thousand of square discarded muds. Generally, the waste slurry is composed of 70% -80% of water and 20% -30% of solid particles, the solid particles comprise drill cuttings, gravel, powder clay particles, organic matters and soluble salts, the waste slurry is a stable colloid system, and solid-liquid separation is difficult to realize by natural precipitation. On the other hand, the waste slurry is mainly alkaline and contains various suspended matters, metal and non-metal ions, so that the natural discharge can pollute water sources, destroy natural vegetation, harden soil, foul river channels, block municipal pipelines and aggravate water and soil loss. In addition, long-term accumulation of the waste slurry not only occupies a large amount of land resources, but also greatly increases the construction cost; the outward transportation needs a special tank car, and the transported waste slurry does not meet the landfill requirement and is difficult to directly use resources and recycle; the open disposal is costly and inefficient. The existing waste slurry treatment methods generally include the following methods: 1) Adding a flocculant to the waste slurry: flocs generated by the method are difficult to accumulate and transport, and particles after being dried are dissolved in the environment to cause uncertain pollution; 2) The flocculation and dehydration filter pressing mode is adopted: the comprehensive cost is high, the softening coefficient of a hard consolidation-solidification product is low, soil hardening is caused by landfill, and the treated slurry is mostly treated by landfill, thereby bringing uncertain influence to the environment.
Disclosure of Invention
In view of the above, the invention aims to provide a planting matrix of a soft consolidation body of waste engineering mud, which is prepared into a planting matrix with a certain water retention and fertilizer retention property and a slow release effect, so that the waste mud is changed into valuable, and the environment is not influenced.

Detailed Description
The waste engineering mud soft consolidation body planting matrix of the embodiment is prepared by mixing a fertilizer, a mud soft consolidation agent and waste engineering mud, and wrapping fertilizer nutrients with the waste engineering mud to obtain the planting matrix, wherein the planting matrix comprises the following raw materials in parts by weight: 300-400 parts of waste engineering mud, 40-60 parts of mud soft consolidation agent, 1-5 parts of ammonium polyphosphate and 10-20 parts of fertilizer; the slurry soft consolidation agent comprises raw materials of water-soluble polymers, polyaspartic acid, four-arm polyethylene glycol, potassium humate, nano attapulgite, styrylpyridine, quinoline carboxylate, xanthan gum, polyoxyethylene-polystyrene-polyoxyethylene block copolymer, a cross-linking agent, calcium chloride, potassium dihydrogen phosphate, a hydrolysable silane compound and an inorganic gelling material, wherein the water-soluble polymers are a mixture of polyacrylamide, sodium alginate, polyvinyl alcohol and water-soluble cellulose; in the process of slurry consolidation, a plurality of crosslinking modes and adsorption action form a network to wrap and fix suspended matters and fertilizers in the slurry, so that the suspended matters and the fertilizers naturally condense and settle together to realize the solidification of the slurry, the inorganic cementing material and silane of the water dispenser can connect particles in the slurry into a non-hydrolyzable network structure through physical and chemical actions, and the particles and an organic polymer network adsorbing a large amount of water form a common consolidation action, so that the hydrolysis tendency of the organic network is reduced, and the stability of gel is improved. In the gel system, one part is an organic hydrogel crosslinking network, the other part is a network structure formed by hydrolyzable silane compounds or inorganic gelled materials and inorganic particles in slurry, an organic/inorganic composite double-network hydrogel ' consolidation object ' is formed, mud and water are locked, and a double-network hydrogel three-dimensional network ' fixes mud particles and water molecules to form a ' soft consolidation body '. One or two crosslinking modes of physical crosslinking and chemical crosslinking are combined in the process of solidifying the waste slurry into a soft solidified body, and the chemical crosslinking relates to covalent bond crosslinking, ionic bond crosslinking and the like. Two nets (inorganic net and organic net) are formed by physical and chemical crosslinking means, so that mud and water are effectively wrapped to form a soft consolidation body with both strength and elasticity. Physical crosslinking enhances the elasticity of the network structure; the chemical crosslinking enhances the viscosity and the strength of the network structure, and is convenient for granulation. Since the crosslinked product of physical crosslinking has elasticity but is easily broken at the crosslinking point when the temperature, pH value and the like are changed, and the crosslinked product of chemical crosslinking has certain strength, the crosslinking covalent network structure can enhance the bonding property of the hydrogel and the particles. Therefore, a composite crosslinking method of physical and chemical crosslinking is preferably adopted, so that the subsequent resource utilization of the treated slurry solidification body is facilitated. The mud consolidating agent can consolidate mud into soft consolidated bodies on site, and the stability of colloid and the water saturation of gel can be improved by the molecular bridging action of the adopted macromolecular additive. The strength of the hydrogel can be improved by adopting the combined action of small molecular materials of quinoline carboxylate, styrylpyridine and a polymer, the biocompatibility inside and outside a gel body can be improved by the four-arm polyethylene glycol, the structure and the performance of the hydrogel can be enhanced and improved by a large number of hydroxyl groups covered on the surface of the nano attapulgite, the viscosity of the gel can be increased, the continuity of a hydrogel sponge structure can be improved, and the wall thickness and the porosity of the sponge structure can be enhanced. And the combination effect of the nano attapulgite and the polyoxyethylene-polystyrene-polyoxyethylene block copolymer can improve the particle dispersibility in the slurry hydrogel. The polyaspartic acid and the sodium alginate can form a complex network structure combining semi-interpenetrating and interpenetrating, and the sodium alginate can improve the aperture size and the number of the formed slurry-separating hydrogel and further improve the adsorption and swelling capacity of the slurry hydrogel. Meanwhile, sodium alginate can also form ion coordination crosslinking with metal ions (such as calcium ions and potassium ions) to form an ion crosslinking network, so that the tensile strength and the elongation at break of the hydrogel can be well improved. The polyacrylamide chains form a covalent bond cross-linked network, the sodium alginate and the ions are cross-linked to form another cross-linked network, and simultaneously, the sodium alginate and the ions are combined with the polyvinyl alcohol to form a physical cross-linked network, so that the molecular chains are entangled under the combined action of the polyacrylamide, the sodium alginate and the polyvinyl alcohol, the network structure of the gel can be improved, the action of the potassium humate is combined, the water loss of the muddy water-containing gel is reduced, the wrapping property of the gel on water and mud is improved, the environmental tolerance of the muddy water-containing gel is improved, and the capability of ensuring insolubility and dispersion of the muddy water-containing gel in rainy days is realized. Xanthan gum can increase the viscosity of the hydrogel. The inorganic gel material and the silane of the water dispenser can connect particles in the slurry into a non-hydrolyzable network structure through physical and chemical actions, and form a common consolidation action with an organic polymer network adsorbing a large amount of water, so that the hydrolysis tendency of the organic network is reduced. The ammonium polyphosphate adopted by the invention can improve the nutrient release speed of the fertilizer. The calcium chloride has outstanding adsorption capacity and low desorption temperature for water, has the functions of resisting and inhibiting microorganisms, does not damage the network structure of a gel system when used, does not collapse the space network structure, and does not influence the water absorption and water retention capacity of a solidified body. The monopotassium phosphate is used as a retarder and a fertilizer, and the blending of other components in the mud soft consolidation agent and the monopotassium phosphate does not weaken the fertilizer effect of the monopotassium phosphate. The potassium dihydrogen phosphate is used as a retarder, the weakly acidic retarder can be subjected to a chemical reaction with the water-soluble polymer in advance after being added, and the cross-linking agent is fully reacted with the water-soluble polymer after a certain time, so that the retarding effect is achieved. The chemical reaction means can promote the chemical crosslinking between the water-soluble polymer and the crosslinking agent in the later period to form a uniform three-dimensional network structure. The invention adopts a mode of combining physical crosslinking and chemical crosslinking: physical and chemical crosslinking synergy mechanisms: the physical crosslinking can entangle molecular chains to form a local network, and a promotion effect is brought to subsequent chemical crosslinking to form a more compact three-dimensional network structure; physical crosslinking is mainly realized through physical force, the crosslinking strength is weaker, and the formed soft solidification body has good elasticity and is convenient to stack and transport; the chemical reaction between the retarder and the water-soluble polymer can promote the chemical crosslinking between the water-soluble polymer and the crosslinking agent in the later period, so that a more uniform three-dimensional network structure is formed. Physical crosslinking enhances the elasticity of the network structure, and chemical crosslinking enhances the viscosity and strength of the network structure.
