The invention discloses an extra-high-pressure wall bushing. The extra-high-pressure wall bushing disclosed by the invention comprises an outdoor bushing, a middle connecting pipe and an indoor bushing which are sequentially connected, wherein the outdoor bushing and the indoor bushing are straight pipes, the lower end of the outdoor bushing and the lower end of the indoor bushing are respectively connected with the two ends of the middle connecting pipe, the outdoor bushing and the indoor bushing respectively incline towards the two outer sides of the middle connecting pipe, and the middle connecting pipe is connected with a ground support. According to the extra-high-pressure wall bushing, because the overall bushing is similar like a V shape, the part of the wall bushing, which is connected with a wall body, does not need to be arranged at a higher position of the wall body and can be supported by the arranged ground support, thereby reducing the pressure on the wall body and lowering the requirement on the mechanical strength of the wall body; after the wall bushing is installed, the outdoor bushing and the indoor bushing extend from the lower position of the wall body to a high position far away from the wall body, so that more low-position space is not occupied, thereby facilitating the arrangement of other things; and the situations that traditional extra-high-pressure wall bushings are inconvenient to transport and lift and parts of traditional extra-high-pressure wall bushings are difficultly processed are completely changed.

The invention discloses T-type oil-water separation equipment integrating two special wettable materials, and belongs to the technical field of wastewater treatment. The T-type oil-water separation equipment is of a three-channel structure and is arranged into a lateral T shape or an inverted T shape according to an oil-water separation system. In the three-channel structure, a vertically-upward channel serves as an oil-water mixing system inlet channel, and the other two channels serve as separation channels. A super-hydrophobic and super-oleophilic separation membrane AW and a super-hydrophilic and underwater super-oleophobic separation membrane AO are arranged in the two separation channels respectively. Compared with an existing oil-water separation mode adopting a single membrane, the problem that a liquid barrier layer is formed due to the large liquid density difference is solved, and continuous oil-water separation is achieved; meanwhile, hydrostatic pressure borne by the separation membranes is reduced in the double-channel separation mode, and the requirement for the mechanical strength of the separation membranes is reduced; continuous oil-water separation without the consideration of the oil-water density difference can be achieved.
