The invention belongs to the technical field of water treatment, and in particular relates to a device and a process for a mass transfer process for treating wastewater through a supergravity enhanced electric Fenton method, aiming at solving the problem of limited mass transfer while treating wastewater through the conventional electric Fenton method. The device comprises a plurality of cylinder cathodes and cathode connecting discs as well as a plurality of corrugated cylinder anodes and anode connecting discs, wherein the corrugated cylinder anodes and the anode connecting discs are static relatively to a shell; the centers of the cathode connecting discs are connected with rotating shafts; intake holes are distributed on the cathode connecting discs; and gas circulating chambers are arranged at the bottoms of the cathode connecting discs. According to the process, a supergravity electric Fenton reaction system is formed through the rotating cathode connecting discs and cylinder cathodes as well as the static anode connecting discs and cylinder anodes, and inflated oxygen. The device and the process disclosed by the invention not only solve the problem of limited mass transfer in the conventional sacrificial anode electric Fenton technology application process, so as to improve treatment efficiency, but also the device is low in liquid holdup, low in load, small in equipment and low in energy consumption.

The invention discloses a water gate structure used in reclamation of land from sea and dam construction, which at least comprises a first water gate used for intake of water and a second water gate used for drainage of water, wherein the first water gate is arranged on a position of the dam, corresponding to a low-sand-content water layer, and the second water gate is arranged on a position of the dam, corresponding to a high-sand-content water layer. The invention also discloses an exchanging method of water body in the reclaimed area of the dam; when the surface of water outside the dam ishigher than the surface of water inside the dam, the first water gate is opened, the second water gate is closed, and the reclaimed area is in a water intake state; and when the surface of water outside the dam is lower than the surface of water inside the dam, the first water gate is closed, the second water gate is opened, and the reclaimed area is in a water draining state. The structure and the method disclosed by the invention not only can play a role of maintaining the seawater in the reclaimed area to be clear and the water quality to be better, but also can achieve the effects of reducing the siltation degree in the reclaimed area and the maintenance cost of dredging in the future.

The invention discloses an efficient edge grinding machine for glass. The efficient edge grinding machine comprises a working table and two fixing plates, the lower ends of the two fixing plates are slidingly connected to the upper end of the working table, the upper ends of the two fixing plates are slidingly connected to the same top plate, two installing cavities are formed in the opposite sidewalls of the two fixing plates, an annular gear rack is driven by a double-axis motor to move to drive a grinding groove to reciprocate, and the grinding groove moves to constantly grind the edge ofthe glass and can be replaced with different grinding grooves according to demands, so that edges of different chamfers will be obtained after grinding; the double-axis motor drives a disc to rotate to drive a piston to move, the piston will extrude air in a piston cylinder into a water spraying frame, and then the flowing speed of water in the water spraying frame is made to be high; in this way,on one hand, a cooling effect can be realized, grinding is easy, and on the other hand, a flushing effect can be realized.
