The invention relates to electro-Fenton reaction waste water treatment equipment comprising electro-Fenton main equipment and an advanced reactor, wherein the electro-Fenton main equipment is internally provided with a first anode plate, a cathode plate and a second anode plate which are horizontally opposite, wherein both sides of the cathode plate are provided with extending cathodes, and the upper part is provided with a water outlet pipe connected with the depth reactor; the advanced reactor is internally provided with packing, an overflow pipe and a reflux pipe; negative poles of two DC power supplies are connected, and positive poles are respectively connected with a first anode and a second anode; an ampere meter respectively monitors working currents of the two DC power supplies; a water inlet pump, a reflux pump and a draught fan supply water and aerate from the bottom of the electro-Fenton reaction waste water treatment equipment; the first anode is a dimensionally stable anode with a titanium based surface coated with a stannum-antimony-iridium-tantalum composite oxide catalyst, and the second anode is a steel plate. When the electro-Fenton reaction waste water treatment equipment works, aerated air generates H2O2 in a cathode region and Fe<2+> in a second anode region, the H2O2 and the Fe<2+> form electro-Fenton reaction with waste water, organic pollutants contained in the waste water are degraded through hydroxyl radicals generated from the electro-Fenton reaction, the electro-Fenton reaction is continued after the H2O2 and the Fe<2+> enters the advanced reactor, therefore reaction retention time is ensured, and large-flow reflux is realized.

The invention relates to a stirring device for a soil body improvement test in the construction of a soil pressure balance shield. The stirring device can be used for an indoor stirring test for testing the frictional property and the stirring torque of a soil body. The device is characterized in that a beam is arranged above a frame-shaped bracket, and a motor, a motor transmission and an ampere meter are arranged on the beam; stirring buckets are fixed on a base, the base is arranged on the frame-shaped bracket, and stirring blades are arranged in each stirring bucket and connected with an output shaft of the motor through a rotating shaft; a series of fixing devices on which stirring buckets in different sizes can be arranged is arranged on the base, and the fixing devices can lift and horizontally slide through a lifting frame at the bottom of the bracket and a base rail; and a computer is connected with the ampere meter so as to record the change process of the motor current along with the time during the stirring process in real time. The invention is used for the indoor stirring test for testing the frictional property and the stirring torque of the soil body, is suitable for a plurality of soil layers and has the advantages of simple and convenient test procedure, real-time current change recording and favorable testing effect.

The invention relates to a charged droplet charge-to-mass ratio real-time measurement device easy to disassemble and assemble. The charged droplet charge-to-mass ratio real-time measurement device easy to disassemble and assemble is composed of a movable base, a support, a supporting board, hangers, an ampere meter tray, a balance tray and a Faraday cylinder. The support is fixedly installed on the base. The supporting board is installed at the upper end of the support. The hangers are installed on the supporting board. The Faraday cylinder and the hangers are connected in a fastened mode. The ampere meter tray is inserted in the middle lower portion of the support. The balance tray is arranged on the base. The height of the Faraday cylinder can be adjusted through the adjustment of the depth of an upper section aluminum tube inserted in a lower section aluminum tube and the angle of the Faraday cylinder can be adjusted through the adjustment of the positions of two sliding supports in the two hangers at the two sides. The charged droplet charge-to-mass ratio real-time measurement device easy to disassemble and assemble achieves the purpose that the charged droplet charge-to-mass ratio is measured in real time through the Faraday cylinder in various severe environments and has the advantages of being wide in application range, convenient to assemble, disassemble and move, low in cost and the like.
