The invention relates to an ozone contact oxidation device for deep and efficient treatment of landfill leachate. The ozone contact oxidation device comprises a water inlet pipeline of the landfill leachate treated by secondary biological treatment, an H2O2 adding device, a gas-liquid mixing pump, a recycling ozone contact oxidation reaction chamber, a reaction chamber, at least three contact oxidation reaction chambers, at least one activated carbon adsorption chamber and a water outlet used for discharging the landfill leachate treated by ozone oxidation treatment. The ozone contact oxidation device remarkably improves the biodegradability of the effluent of the landfill leachate treated by secondary biological treatment; by means of the addition of granular active carbon, the ozone content of liquid phase of the landfill leachate at the water outlet is very low, and a subsequent biological treatment device can be directly filled with the landfill leachate at the water outlet; furthermore, the utilization rate of ozone is more greatly improved by adjusting the ozone filling proportion of all the contact oxidation reaction chambers through an ozone recycling pipeline, so that the operating cost of the deep treatment of the landfill leachate is lowered.

The invention belongs to the technical field of occupational protection, and particularly relates to guard stage equipment for providing comprehensive protection for an outdoor fixed duty post and a control method thereof. The guard stage equipment comprises a base part, a casing and supporting part, an umbrella part, an automatic control module, a power source control module, a storage battery pack, display processing equipment and the like. The guard stage equipment is comprehensive protection equipment for the outdoor fixed duty post, a stable clean air area can be formed within a certain range of open space of standing positions of traffic police and other outdoor fixed duty post personnel, the problem that ozone generated by static dust removal and air purifying equipment hurt the human body is effectively solved, and outdoor air purifying and output directly aiming at outdoor personnel are achieved. Through intelligent induction, automatic control, heating, cooling and other functions and high impact resisting strength, guarantees are provided for the body health and life safety of the outdoor fixed post duty personnel in the industries of the traffic police, armies, armed police, public security and the like.

The invention discloses a special-purpose needled felt for complex condition coal fired power plants, which comprises a dust receiving surface, an auxiliary filter layer, an strengthen base cloth layer and a support layer which are orderly composited together by needling, wherein the dust receiving surface is blended by polyphenylene sulfite (PPS) fibers, polytetrafluoroethylene (PTFE) fibers and polyimide (PI) fibers according to proportion of 1:(0.2-0.5):(0.2-0.5), the auxiliary filter layer and the support layer are respectively needled by the PPS fibers, and the strengthen base cloth layer is interlaced by PTFE filament yarns in longitude and latitude. The invention further discloses a method for preparing the special-purpose needled felt for the complex condition coal fired power plants. The dust receiving surface is blended by the PPS fibers, the PTFE fibers and the PI fibers, thereby being low in cost, and increasing transverse and longitudinal strength of the special-purpose needled felt. Probability of intercept and filter precision of dust are increased through element felt preparation, immersion treatment, calendering processing and singeing process, thereby leading instantaneous using temperature of the special-purpose needled felt to increase and to be less affected by ozone, increasing oxidation resistance, prolonging service life, being further capable of improving strip ratio of the dust, increasing ventilation property of the special-purpose needled, and reducing operation energy consumption.

The invention discloses an air disinfecting device, comprising: a DC high-voltage power supply, a current limiting resistor, an air supply device and a disinfecting module; wherein, the disinfecting module includes an air inlet; The air supply device is placed at the air inlet of the disinfecting module; the air supply device is used to send the surrounding air to be disinfected into the disinfecting module through the air inlet; the DC high voltage power supply is used to provide the air discharge required Voltage and energy; the disinfecting module is used to ionize the air through high-voltage discharge to generate air plasma to complete the disinfecting of the air. The device generates air plasma through high-voltage discharge, and uses the heat energy in the plasma and short-lived high-activity free radicals to completely kill microorganisms in the treated air in a short time, prevent residues, and has a broad spectrum . In addition, the device has a simple structure, is convenient to use, does not cause harm to the human body, and does not cause secondary pollution.

The invention relates to a treatment process and device for aquaculture and disinfection and organic removal of circulating cultivation water. The device adopts a static mixer for mixing ozone and is mainly used for sterilization, and the loss of pressure head of the static mixer is less; after being treated in an ultraviolet radiation area, the cultivation water is sterilized and organics are removed, and then the cultivation water enters a biological stuffing reaction area for mainly removing organics. The device integrates ozone dissolution and reaction, has a simple structure, and can be used for sterilizing cultivation water bodies, degrading organics, removing ammonia nitrogen and water color, and increasing dissolved oxygen.
