  • Publication number: 20240117467
    Abstract: Provided are an electrokinetic device and method for in-situ leaching of uranium, belonging to the technical field of in-situ leaching of uranium. The electrokinetic device for in-situ leaching of uranium includes an injection well, a pumping well, a positive electrode, a negative electrode, leaching solution, and a direct current power supply. Uranium ore is provided between the injection well and the pumping well, the negative electrode is arranged in the injection well, and the positive electrode is arranged in the pumping well. The leaching solution is injected from the injection well, flows through the uranium ore, and then is pumped from the pumping well for uranium extraction. The direct current power supply is respectively connected to the positive electrode and the negative electrode, and is configured to apply direct current between the positive electrode and the negative electrode to promote the pooling of uranium-carrying ions towards the pumping well.

  • Publication number: 20240082160
    Abstract: An amlodipine dry suspension, comprising a diluent, a suspending aid, etc. and being free of surfactants. A preparation method therefor comprises the following steps: a) preparing an aqueous mixture 1 containing amlodipine besylate by using a high-speed homogenization method; b) adding sodium benzoate to the mixture 1, and homogenizing same at a high speed to obtain a mixture 2; and c) granulating the mixture 2 and other components, and then drying same. The raw materials are homogenized and mixed at a high speed, no surfactant is added during the preparation, amlodipine is fully wetted by using a high-speed homogenization process, prescription components are simplified, and the amlodipine dry suspension is more suitable for children to use. Compared with ultrasonic stirring, scaled-up and industrial production are easier to realize for the high-speed homogenization process, and at the same time, the preparation is good in stability and convenient to carry.

  • Publication number: 20230357066
    Abstract: The present invention discloses a method for promoting methane production by anaerobic digestion in a high ammonia-nitrogen habitat using a biochar with a high carbon-to-nitrogen (C/N) ratio. In this method, a biochar material prepared by dry distillation and carbonization is added to municipal sludge for medium-temperature anaerobic digestion treatment, which increases the efficiency of methane production from sludge by anaerobic digestion in different ammonia-nitrogen stress habitats, thereby realizing the utilization of sludge as resources.

  • Publication number: 20230008207
    Abstract: Disclosed is a method for recovering phosphorus from sludge rich in chemical phosphorus precipitates using a high-protein biomass waste, comprising introducing the sludge rich in chemical phosphorus precipitates into an anaerobic fermenter, adding a certain amount of a high-protein biomass by-product, sealing the fermenter and fermenting for 4-7 days. The method can effectively increase the phosphorus release efficiency from the sludge, and also generate volatile short-chain fatty acids and ammonia nitrogen in high concentrations. After dewatering, phosphorus and part of ammonia nitrogen can be recovered in a form of high-purity struvite crystals only by addition of a magnesium salt and adjustment of pH to 7.5-9.0. The volatile short-chain fatty acids can be used as an economical carbon source. The method allows simultaneous utilization of two solid wastes to recover carbon, nitrogen and phosphorus resources, and can reduce the usage of chemical reagents, saving the treatment cost.
