The invention discloses a waterproof glue for external wall ceramic tile, which is formed by formulating acrylic emulsion, ethylene glycol, film forming auxiliary (dodecyl ester), alkali swelling thickener, antiseptic and defoaming agent, the waterproof glue has the advantages of being waterproof, joint-filling, transparent, rich in elasticity, environmentally-friendly, bright and clean, simple and convenient in applying, etc., and is free from toxicity, odor and new pollution even in case of the long-term use thereof and is also age resisting, therefore, the waterproof glue for external wall ceramic tile is an ideal product for environmental protection.

The invention discloses a Pd/TOC photocatalyst, a Pd/CdS/TOC photocatalyst, a preparation method and an application thereof. The Pd/TOC photocatalyst is prepared by taking TOC as a load object and loading Pd on TOC. The Pd/CdS/TOC photocatalyst is prepared by further loading CdS on the basis of the Pd/TOC photocatalyst. Various photocatalysts prepared according to the invention are all green and environment-friendly materials; no new pollution is generated after degradation of the photocatalysts; degradation efficiency is high; applicable environment is extensive; the photocatalysts can be used for treating wastewater; the efficiency of degrading 2,4-dichlorophenol is high; the popularization and application of photocatalysts have huge advantages.

The invention discloses a method for recovering lithium and potassium from high-lithium-potassium anode carbon residues or high-lithium-potassium electrolytes. The method comprises the following stepsthat (1) the high-lithium-potassium anode carbon residues or the high-lithium-potassium electrolytes are finely ground as raw materials, mixed with a concentrated sulfuric acid solution, and heated to 280-500 DEG C for reacting; (2) water is added into the reacted materials for leaching, and primary filtrate is filtered and separated out; (3) the pH value is adjusted to be equal to 6-8 when the temperature of the primary filtrate is less than or equal to 30 DEG C, and secondary filtrate is obtained through filtering and separating; (4) the secondary filtrate is cooled to minus 5 DEG C to-minus 10 DEG C, and Na2SO4 is separated out; third filtrate is filtered and separated out; (5) after the third filtrate is heated to 90-100 DEG C or boiled, Na2CO3 is added and Li2CO3 is precipitated andseparated out, and the Li2CO3 and fourth filtrate are filtered and separated out; and (6) the fourth filtrate is cooled to minus 5 DEG C to-minus 10 DEG C, and Na2SO4 is precipitated out, a K2SO4 solution is filtered to separated out, and a K2SO4.xH2O product or a K2SO4 product is obtained by concentrating or dehydrating. The method is low in process flow cost and convenient to operate, almost does not generate new pollution while the waste is fully recovered, and has a good popularization prospect.

The invention is a kind of dual environmental protection building surface ornamenting material produced by using brick powders of grinded waste construction clay bricks as main materials and its producing method. The invention makes clay brick powders as main materials, and is compounded from such chemical industry materials as acrylic acid emulsion, sodium hexametaphosphate, sodium benzoate, glycol, trimethylene glycol, polydimethyl siloxanes, methylcellulose and titanium oxide powder as per certain proportion. The invention has simple technics, convenient and sanitary construction, and can be used both in upscale wall surface and surfaces of column, tablet and board. After ornamented, it has elegant and vivid brick wall style, especially suitably used for outer ornament and repair of building wall surfaces whose outer walls need brick wall structures.

The invention has simple process, easy operation, clearness and wide application in hospital, canteen, company and channel or the like. Via the luminous property, the invention can be used as indication and decorative material, particularly as aqueous environment-friendly material, without toxicity, smell and pollution in production, construction and application.

The invention discloses a method for preparing vanadium trioxide by recycling anode electrolyte of an invalid vanadium battery. The method comprises the following steps: a, measuring tetravalent vanadium ion concentration and pentavalent vanadium ion concentration of the anode electrolyte of the invalid vanadium battery; b, adding a carbon-based adsorbent into the electrolyte in the step a, adsorbing, filtering and drying to obtain a vanadium-containing adsorbent; and c, roasting the vanadium-containing adsorbent obtained in the step b under the protection of an inert atmosphere to obtain a vanadium trioxide product. According to the method for preparing the vanadium trioxide by recycling the anode electrolyte of the invalid vanadium battery, the problem of disposal of the electrolyte of the existing invalid vanadium battery can be solved, a high-added-value vanadium trioxide product can be obtained, and the method is simple in process, free of pollution, environmentally friendly and good in application prospect.
