A building drainage concentrator relates to a drainage concentrator applied to toilets, balconies and kitchens. The building drainage concentrator consists of a stand pipe drainage section (1), a horizontal pipe drainage concentrating section (2) and a water seal component (3). A horizontal surface (9) of the horizontal pipe drainage concentrating section (2) and an inner wall below are planes or cambered surfaces approximate to planes. A maximum distance of a horizontal opening (15) of a channel (13) on the top of the concentrating section of the horizontal pipe drainage concentrating section (2) that is communicated with the stand pipe drainage section (1) is greater than a maximum distance of a vertical opening (16). The top of the water seal component (3) on one side of the horizontal surface (9) is communicated with the bottom of the water seal component; a floor drain cover (23) is arranged above the water seal component. The minimal distance L between the outside of the upper portion (18) of the water seal component and the outer wall of the adjacent stand pipe drainage section is ranging from 40mm to 450mm. The lowest end at the inlet of a horizontal pipe port (44) is higher than the horizontal surface (9). In case of the floor drains are installed, the building drainage concentrator is able to use the toilet, the kitchen and the balcony when the water is drained at the same floor of the building, without any fall slabs or slightly descending floors.

The invention discloses a drainable manhole cover with combined steel plates and concrete filled steel tubes. The drainable manhole cover comprises a concrete cover body (1), wherein a steel plate (2) is embedded in a bisecting surface in the thickness direction of the concrete cover body (1), cylindrical steel tubes (3) symmetrically distributed about the steel plate (2) are connected with the upper surface and the lower surface of the steel plate (2), and drain pipes (5) penetrating through the upper surface and the lower surface of the concrete cover body (1) are arranged in the steel tubes (3). According to the drainable manhole cover with the combined steel plates and concrete filled steel tubes, the steel plate (2) is embedded in the concrete cover body (1), the upper surface and the lower surface of the steel plate (2) are symmetrically connected with the steel tubes (3), the drain pipes (5) are introduced in the steel tubes (3), the distribution of the steel tubes (3) can be regulated and changed according to the shape of the manhole cover and the stress situation, and because the steel plate (2) and the steel tubes (3) are common components, the manufacturing cost is relatively lower. The design of gaps of the steel tubes (3) can enhance connection between the steep tubes (3) and concrete, can also bear corresponding load, and enhances the strength of the manhole cover; and the drain pipes (5) can drain water on the basis of not influencing a reinforcement structure.

The invention discloses an industrial sewage treatment device that can be automatically cleaned based on 5G technology, including a sewage treatment tank and a filter tank. The other side of the suction pump is provided with a main pipe, and the main pipe is connected to each other through the cross pipe, the stirring and cleaning pipe, the filtering and cleaning pipe, and the sewage reuse pipe. The stirring and cleaning pipe is installed with a first solenoid valve, so the One end of the stirring and cleaning pipe away from the four-way pipe is provided with a stirring and cleaning nozzle, a second solenoid valve is installed on the filtering and cleaning pipe, and one end of the filtering and cleaning pipe away from the four-way pipe is provided with a filtering and cleaning nozzle, The invention is provided with stirring and cleaning nozzles and filtering and cleaning nozzles, which facilitates cleaning of the stirring and filtering structures in the sewage treatment tank, and saves more water; the sewage is circulated in the process of "pressing rake", which does not increase the amount of sewage, and saves energy and reduces emissions. , the effect is remarkable.

The invention relates to a floor drain, in particular to a floor drain with an automatic blocking / drainage device, the floor drain can automatically open or block the mouth of a downpipe at any time so as to prevent the occurrence of ground water impoundment and indoor air pollution by using a special mechanism when the floor drain is used or not used. The floor drain comprises a floor drain body, a floor drain cover, an inner core, a floating body cover and a reducing downpipe, wherein the floor drain cover is covered on the floor drain body, and fixed by a fastening pin; the inner core is sleeved on the reducing downpipe, and can move upwards and downwards by a handle; and the floating body cover is arranged on the inner core and the downpipe, once being used, the floating body cover can achieve a water-seal / cover-seal double sealing effect. When the dirt deposited on the bottom of the floor drain is removed, the removing of the dirt can be realized only by lifting the inner core to flush with water, and the process of removing is simple and quick.
