The invention discloses a chlorine-free swimming pool system and a full flow and full process ozone disinfection method. The system comprises a swimming pool and a disinfection system; a raw water pipe of the disinfection system is communicated with a overflow gutter of the at the upper part of the swimming pool; a water inlet pipe of the disinfection system is communicated with a backwater nozzle at the bottom part of the swimming pool; a raw water inlet of the disinfection system is connected with a clear water outlet sequentially by the following pipelines: a balancing pool, a water circulating pump, an ozone water mixer, an ozone reaction pot and an ozone-removing device and a filter thereof; the ozone reaction pot air vent valves at the top part of the ozone-removing device and the filter thereof are respectively connected with a tail gas resolver. In the invention, chlorine preparation is completely not used in the normal process of processing water in the swimming pool with ozone disinfection adopted, thus greatly reducing use of chlorine in the water, and preventing generation of peculiar smell and harm to human body caused by generation of by-product cancerogen haloform. The method of the invention features safe operation, reliability, and high degree of automation, thereby being capable of being used as a main water processing method in a high standard and underload swimming pool.

The invention discloses a particle electrode catalyst filling for three-dimensional electrode and preparation method, calculated by weight percent, the material comprises activated charcoal 50-54%, adhesive 14-19%, the initiating agent comprises 13-16% ferrum oxide, 12-15% copper oxide, 4-7% manganese oxide, 1-1.5% zinc oxide, 0.5-1% zirconium oxide, 0.5-1% cerium oxide.

The invention relates to bactericide for oil fields, in particular to poly-guanidine SFT bactericide. The poly-guanidine SFT bactericide solves the technical problems of sterilizing and removing impurities in re-injection water in oilfields and waste water in oil refineries, and comprises the following raw material by weight in parts: 10-15 parts of hydrochloric polyhexamethylene guanidine, 2-4 parts of geramine, 5-7 parts of polyhexamethylene biguanidine, 1-3 parts of chlorine hydride guanidine, 2-4 parts of ferric sulfate and 20-30 parts of water. The poly-guanidine SFT bactericide can be adopted as the bactericide and water treatment agent of the re-injection water in the oilfields and the waste water in the oil refineries, not only has excellent anti-bacterial effect and sterilization effect, but also has a certain flocculate action, has no bubbles while being mixed with water, does not need de-foaming agent, and has good effects to accumulating oil, displacing oil and treating waste water.
