The invention discloses a method for treating microcystis aeruginosa based on flocculation-coverage coupling of natural soil. The method comprises the following steps: 1) performing high-temperature sterilization after soil crushing; 2) organically and uniformly mixing with an organic polymer solution to form a modified soil flocculant; (3) carrying out flocculation treatment on the microcystis aeruginosa; and 4) after flocculation treatment, covering treatment is carried out by adopting soil gravel. According to the invention, the organic polymer solution is utilized to modify the soil to obtain the efficient flocculant, algae cells are settled to the surface of the bottom mud by utilizing the settling effect of the soil, and the covering layer is utilized to prevent the re-suspension of the algae cells. The technology can be used for effectively and efficiently treating the eutrophic water body.

The invention relates to a composite extractant used in a metal indium extraction process. The composite extractant is formed by mixing Bis(2-ethylhexyl)phosphate (P204), trioctylphosphine oxide and hexylphosphine oxide mixture liquid (C923) and trialkyphosphine oxides (TRPO) according to certain proportion. After being diluted with sulfonated kerosene, the composite extractant is used as an extractant used for metal indium extraction. The composite extractant has good chemical stability, good selectivity and high indium extraction efficiency which can achieve more than 90%, simultaneously canreduce the extractant emulsification, is easy for re-extraction, and the demand to extraction conditions of a system is not high.

The invention relates to a technique for recovering toxic arsenic compounds during metal indium extraction by utilizing waste residues generated from lead and zinc smelting. The technique takes saturated aqueous solution of sodium sulfide as precipitant and regulates the system acidity and temperature to recover or remove arsenic in solid forms, which is contained in leachate that is obtained after the waste residues generated from the lead and zinc smelting undergo acid leaching. After analyzing, the technique achieves an arsenic removal rate (recovery rate) as high as 97.3% and simultaneously little indium loss, prevents the arsenic from being reduced into arsine gas which can escape away, and simultaneously does not affect the extraction and enrichment of the indium.

The invention provides a method for extracting metal indium from waste residues generated from lead and zinc smelting. The method is implemented by the following steps: carrying out low-temperature and low-acid leaching on the waste residues generated from the lead and zinc smelting, and removing acid-soluble metals from the waste residues; then carrying out high-temperature and high-acid leaching to obtain indium; and obtaining the metal indium after extraction, re-extraction, reduction and refining. The method has relatively short process flow and low production cost, generates a great amount of byproducts, can comprehensively recover and recycle waste water and the waste residues, is not only good for environmental protection, but also realizes cyclic and comprehensive resource use. The total recovery rate of the metal indium is 70-80%, and the recovery rate of high-purity metal indium is up to 99.995%.
