Abstract

The invention relates to the technical field of waste tin sludge treatment, in particular to a method for preparing a bio-organic fertilizer from waste tin sludge. The invention adopts a main technical scheme comprising the following steps of: treating tin sludge through water washing, electrolysis and biological fermentation sequentially, namely separating part of metal precipitate mainly through water washing and then separating part of metal through electrolytic reduction; and treating the residual non-metal parts by using a biological reagent to obtain the bio-organic fertilizer. The method for preparing the bio-organic fertilizer from the waste tin sludge has the advantages of low production cost, high profit and simple process and production equipment. Particularly, the bio-organic fertilizer prepared by the method comprises a moisturizing factor and a great variety of nutritional components and can be increased and supplemented continuously without causing soil acidification.

Description

technical field [0001] The invention belongs to the technical field of waste tin sludge treatment, in particular to a method for manufacturing bio-organic fertilizer by using waste tin sludge. technical background [0002] Because tin has many excellent properties, the tin slag produced in industry is usually recycled directly; in order to purify the waste tin slag, people will use the tin slag reducing agent to treat the tin slag first, because most of the tin slag is the oxidation of tin Substances (tin oxide or stannous oxide), a small part is the compound of tin and copper or its sub-impurities, the reducing agent is to carry out a redox or replacement reaction on the oxide of tin and its compound, reduce the tin, and produce other A small amount of substances that cannot be melted in molten tin (usually some organic substances such as carbides and phosphorus and nitrogen), the residue after reduction by tin slag reducing agent is called tin mud. Tin slime is generally ...
