The invention relates to the technical field of sodium persulfate wastewater treatment, in particular to a sodium persulfate wastewater treatment, recovery and purification device, which comprises a base and a cushion block, an evaporator is fixedly connected to the center of the upper end face of the base, the cushion block is arranged on the left side of the evaporator, and the lower end face of the cushion block is fixedly connected with the base. A pre-filtering device is fixedly connected to the upper end face of the cushion block, a storage pipe is arranged on the right side of the evaporator, a discharging pipe is fixedly connected to the lower end face of the evaporator, and the other end of the discharging pipe is fixedly connected with the storage pipe; according to the wastewater treatment device, a rotating motor, a rotating shaft, a heating plate, heating chambers and a rotating table are arranged, the rotating motor rotates to drive the rotating shaft to rotate, so that the rotating shaft is heated by the heating plate, meanwhile, wastewater can be driven to rotate and stir, and in the heating process of the heating chambers on the two sides and the heating plates, the heating efficiency is greatly improved; the evaporation efficiency is higher, and the practical value is very good.

The invention relates to filter paper with high filtering efficiency, and a preparation method thereof. The filter paper with high filtering efficiency disclosed by the invention is composed of the following raw materials by weight: 50-60 parts of jute pulp, 45-50 parts of wood pulp, 20-25 parts of polystyrene fibers, 3-5 parts of sodium carboxymethyl cellulose, 3-4 parts of a nano carbon powder, 1-2 parts of feldspar powder, 1-2 parts of alum powder, 1-2 parts of 4,4'-diphenylmethane diisocyanate, 2-3 parts of diethylene triamine, 2-3 parts of polyamide wax micropowder, 0.8-1 part of bis(P,P-bis-ethylhexyl diphosphato)ethanediolato titanate, 0.4-0.6 part of an antioxidant DSTP, 0.5-0.6 part of sodium persulfate, 2-3 parts of ethylene glycol, 6-7 parts of rosin, 15-20 parts of absolute ethyl alcohol, 3-4 parts of nano diatomite, 0.8-1 part of polyoxyethylene octyphenyl ether, 0.3-0.4 part of Gamma-(2,3-epoxypropoxy)propyl trimethoxysilane and a proper amount of water. The filter paper produced by the invention has high filtration precision, high filtration efficiency, small air resistance and strong pollutant-holding capacity, and is environment-friendly.

The invention discloses a preparation method of a bathroom water draining pipeline dredging agent. The bathroom water draining pipeline dredging agent comprises, by weight, 25%-35% of sodium carbonate, 5%-15% of sodium persulfate, 25%-35% of sodium hydroxide, 10%-15% of potassium permanganate, 10%-15% of aluminum particles and 5%-7% of a drying agent. The preparation method comprises the steps that sodium carbonate, sodium persulfate, sodium hydroxide and potassium permanganate are added into a mixer to be mixed at a certain vulcanizing temperature in an environment with a certain humidity; amixture obtained in the step 1 is added into a crushing machine to be crushed, and powder is prepared; the powder obtained in the step 2 is fed into a granulating machine to be granulated and then fedinto a screener to be screened, screened qualified products are fed into a moistureproof treatment device to be subjected to moistureproof treatment, and screened unqualified products return back tothe crushing machine to be crushed; and the qualified products obtained in the step 3 are fed into the mixer to be fully mixed to aluminum particles, drying agents are put into small packaging bags, and the products are obtained. The bathroom water draining pipeline dredging agent has the advantages that the dredging effect is good, transportation is convenient, and the practicability and the safety are achieved.
