    摘要: A process for constructing a soil-based rhizosphere flow-through system to break down contaminants in contaminated water. The process includes the steps of: providing plants planted in soil in a test bioreactor, the plants providing a rhizosphere; exposing the rhizosphere to the contaminated water; extracting microorganisms from the rhizosphere following their exposure to the contaminated water; preparing a microbial suspension from the extract; subjecting the microbial suspension to growth conditions to increase the concentration of the microorganisms, thereby preparing a soil conditioner; adding the soil conditioner to soil in a contained area having a water flow inlet and outlet; and planting a plurality of plants in the soil, the plants being of the same species as the plants of the test bioreactor.

    摘要: A polyacrylamide-based composition as a microemulsion is provided in the form of a water-in-oil microemulsion with polyacrylamide dissolved in the water phase, and further comprising ethylene oxide-propylene oxide block copolymer. Specifically, the present invention includes, dissolved in the water phase, a polyacrylamide copolymer and an EO/PO block copolymer, with the water phase mixed with an oil phase. Preferably, the present invention may further comprise the presence of at least one fatty acid and/or at least one nonionic surfactant to stabilize the microemulsion. In addition, the present invention may further comprise effective amount of other components, such as pesticides and/or fertilizers, that may be delivered to trees, plants or other vegetation.

    摘要: A plastic gel grouting material, which comprises a silica type non-hardening powdery material and water or a silica type non-hardening powdery material, a calcium type hardening developing material and water as active ingredients, is statically pressure-injected into a soft, loose or weak ground to thereby form masses derived from the grouting material per se in the ground, and concurrently therewith, to compact the surrounding earth and sand, thereby increasing density of the ground.A plastic gel grouting material is provided which loses its flowability with time or by dewatering to form masses derived from the grouting material per se in a ground and which comprises a silica type non-hardening powdery material and water or a silica type non-hardening powdery material, a calcium type hardening developing material and water as active ingredients.
