Abstract: The present invention mainly comprises a feed formulation containing soybean curd residue and a method for preparing the same. The preparation steps are as follows: (1) sterilization: sterilization of soybean curd residue; (2) preparation of a feed for black soldier fly: mixing the sterilized soybean curd residue with a solution of effective microorganisms; (3) preparation of a black soldier fly larvae powder: drying and grinding the black soldier fly larvae (BSFL) into powder; (4) addition of nutrients and BSFL powder: mixing the sterilized soybean curd residue with various nutrients and BSFL powder to obtain a mixture; (5) addition of the solution of effective microorganisms: mixing the solution of effective microorganisms with the mixture of step (4) to obtain a feed mixture; (6) fermentation: fermenting the feed mixture anaerobically to obtain a fermented feed, wherein the fermented feed is a feed formulation containing soybean curd residue.

Abstract: A method for removing pollutants by using a mixed microbial solution of beneficial microorganisms to enhance electrokinetic force. It includes a mixed microbial solution; an anode tank and a cathode tank are connected to an external power supply. A soil tank contains contaminant soil and the soil tank is positioned between the anode tank and the cathode tank which are parallel to each other. A soil-retaining net is disposed over the soil. The external direct current is used to allow the mixed microbial solution to transfer in the soil tank.

Abstract: A method for enhancing biotransformation of groundwater contaminants is provided. The method comprises steps of providing an injection column at an upstream of a contaminated source for injecting a compost solid; providing a recirculation device at a downstream of the contaminated source; forming a compost liquid by mixing surface water or groundwater from the recirculation device with the compost solid, and the groundwater bringing the compost liquid to the contaminated source at the downstream; and producing a reaction at the contaminated source and the downstream. Also, the groundwater contaminants can be adsorbed and biodegraded in the injection column at the upstream by the recirculation of the recirculation device.
