The invention relates to a culture medium for culturing haematococcus pluvialis by using brewery wastewater, of which the formula is as follows: 80 ml of brewery wastewater, 28 mg of sodium citrate, 20 mg of urea, 12 mg of potassium dihydrogen phosphate, 150 mg of fructose, 45 mg of yeast extract powder, 50 mg of casein tryptone, 12 mg of ammonium citrate, 25 mg of whey powder, 30 mg of lactose, 60 mg of glucose, 1.8 ml of horse manure leachate, 2 ml of fermented soya-bean milk, 100 mg of sorbitol, 24 mg of soluble starch, 25 mg of soytone, 28 mg of beta-sodium glycerophosphate, 12 mg of an edetic acid, 10 mcg of vitamin B1, 21 mcg of vitamin B1, 1.8 ml of soil extract, 1.5 ml of human urine, 2.4 ml of chicken manure leachate, and 1000 ml of pure fresh water disinfected by sodium hypochlorite. An important bioactive substance-astaxanthin can be obtained. The culture medium is low in cost, uneasily polluted, and can be reused; and due to the mixed utilization of organic fertilizers and inorganic fertilizers, the growth rate and astaxanthin content of haematococcus pluvialis are significantly increased, and the yield is increased by 270%.

A thin-film capacitor housing heat dissipation coating is prepared from, by mass, 35 parts of resol, 3 parts of gelatin, 5 parts of glycidyl methacrylate, 3 parts of sodium dodecyl benzene sulfonate, 3 parts of gloss oil, 5 parts of dimethyl dicarbonate, 3 parts of olive oil, 3 parts of colored glaze carbylic acid, 3 parts of olive oil, 3 parts of graphene, 5 parts of pigment, 50 parts of distilled water, 3 parts of benzoyl paeoniflorin, 3 parts of sodium hypochlorite, 5 parts of a modifying agent, 3 parts of calcium carbonate, 3 parts of glacial acetic acid, 3 parts of magic acid, 5 parts of polyester resin, 3 parts of potassium dihydrogen phosphate, 1 part of sodium phosphate, 3 parts of aluminum silicate, 3 parts of imidazole, 3 parts of cohesive soil, 3 parts of polyvinyl alcohol and 3 parts of sodium borohydride. The modifying agent is added in a traditional formula to perform modification processing, the coating coated on a capacitor housing can effectively guide capacitor inside temperature rising due to work to the housing and convert heat into infrared radiation waves, and the working voltage of a capacitor can be also in a stable state in addition to prolonging of the service life of the capacitor.

The invention relates to a method for preparing mercury-free ammonium detection test paper, and belongs to the field of analytical chemistry. Based on filter paper of 1 square centimeter, the ammonium test paper consists of 0.5 to 5.6 milligrams of soaked phenol, 0 to 0.1 milligram of sodium nitroprusside, 0.35 to 4.5 milligrams of disodium hydrogen phosphate, 3.0 to 10 milligrams of sodium phosphate, 0.3 to 4.6 milligrams of sodium hypochlorite and 0.15 to 0.5 milligram of sodium hydroxide. The reagent content of the ammonium test paper is only one percent of that in other ammonium ion test methods. The test paper of the invention has the advantages of simple manufacturing, convenience to carry, simple, convenient and rapid operation, vivid detection, high selectivity and capability of judging the ammonium ion content of a sample by visually comparing the color of the developing test paper with that of a standard color card. Reagents used by the method are ordinary chemical reagents which are non-toxic, safe and reliable and can be used for testing the ammonium content of various nitrogen fertilizers, soil, crop hydroponics nutrient solution, different kinds of ammonium-containing solution and sewage.

The invention discloses a method for preparing sodium hypochlorite by using reverse osmosis concentrated water, which comprises the following steps: S1, the reverse osmosis concentrated water enters a softener for softening treatment and then enters a carbon adsorption device, the softened water subjected to carbon adsorption treatment enters a water storage tank, and the water storage tank pumps the softened water into an electrolytic bath for electrolysis to prepare sodium hypochlorite; s2, when the reverse osmosis concentrated water is electrolyzed in the electrolytic tank, an aeration device is used for carrying out bottom aeration treatment on the solution, aerated gas and gas generated by electrolysis enter a chlorine gas collecting system together, sodium hypochlorite generated by the chlorine gas collecting system and the electrolytic tank is guided into a sodium hypochlorite storage tank to be stored, and gas generated by the chlorine gas collecting system is discharged. The reverse osmosis concentrated water is used as an electrolysis raw material, so that the problem of water plant concentrated water treatment is effectively solved, and sodium hypochlorite can be produced as a disinfectant for each process of a water plant for later use.
