Fluoride removing technology for wastewater discharged from polysilicon solar photovoltaic cell productions

The invention discloses a fluoride removing technology for wastewater discharged from polysilicon solar photovoltaic cell productions. The technology comprises the steps that: step 101, high-fluorine water and low-fluorine water are both delivered to a regulating tank; calcium oxide or calcium hydrate is added to the tank, and is dissolved by stirring; and the pH value of the solution in the regulating tank is regulated to 7; step 103, treated high-fluorine water and low-fluorine water are delivered to a reaction tank; a fluoride removing flocculating agent which is a permanganic composite salt containing hydroxy is added into the tank; the solution is dissolved by stirring; the pH value of the solution in the reaction tank is regulated to a value between 6 and 7; when pink color in the reaction tank is disappeared, flocculated deposition is formed; and water in the reaction tank is then filtered and discharged. With the fluoride removing technology for wastewater discharged from polysilicon solar photovoltaic cell productions, salt content and chemical oxygen demand of the fluoride-containing wastewater can be reduced through water treatment, F- content of the fluoride-containing wastewater can also be reduced, and secondary pollution is not brought to the fluoride-containing wastewater.

External medicine for curing lepriasis old ulcerative-point erosion as well as burns and scalds

The invention relates to an external medicine for curing lepriasis old ulcerative erosion as well as burns and scalds, which belongs to the technical field of traditional Chinese medicines. The external medicine mainly comprises the following bulk drugs according to weight parts: 25-35 of pearl powder, 5-15 of panax pseudoginseng, 5-15 of cactus and 3-8 of coptis root, and the bulk drugs are prepared, respectively crashed, screened by 250-mesh sieve, mixed and evenly stirred to produce medicinal powders. When the external medicine is used, carrion at an ulcerative point is firstly cleaned, the medicinal powders are then directly spreaded on a wound of the ulcerative point, and the wound is cleaned and the medicine is changed once a day till the wound complete heals. The medicine has pink color, faint scent, pungent, mild, bitter property and flavor as well as toxicity, has the functions of clearing away heat and toxic materials, eliminating dampness and diminishing swelling, draw out pus by applying a plaster to the affected area, reliving pain and repelling insects, promoting circulation of blood and activating blood circulation as well as healing wound and promoting granulation, is suitable for curing lepriasis old ulcerative-point erosion and burns and scalds of ordinary persons and has good healing efficacy, fast healing effect and no scars after healing.

Method for detecting content of antimony in liquid product

The invention discloses a method for detecting the content of antimony in a liquid product. The method comprises the following steps in sequence: A, dissolving and preparing a liquid sample: dissolving the liquid sample by concentrated sulfuric acid, cooling to 35-45 DEG C, adding urea until no white smoke is generated, adding thiourea with the mass using amount which is 0.5-2 times of the mass of the liquid sample under a condition that the temperature is not higher than 40 DEG C, adding water with the adding amount which is 100-500 times of the mass of the liquid sample to realize dilution, adding 37% hydrochloric acid in mass to obtain a solution, boiling the solution, keeping micro-boiling for 2-3 minutes, and cooling to 65-75 DEG C to obtain a solution to be detected; B, detecting the content of the antimony in the liquid sample: dropwise adding 0.1% methyl orange indicating agent into the solution to be detected, keeping the temperature of the solution to be detected at 65-75 DEG C, and titrating the solution to be detected through standard potassium bromate solution until the pink color disappears. According to the detection method disclosed by the invention, no special analyzer is needed; the method is simple, quick, accurate, wide in application range and high in selectivity.
