The invention relates to an integrated waste water treating tank, which comprises a treating tank, wherein the two sides of the treating tack are respectively provided with a waste water inlet and a cleaning water outlet; according to the flow direction of water flow, the inner chamber of the treating tank is divided into a grille filter screen room, an active sludge anaerobism room, a biochemical degradation room and a cleaning water area by baffle plates; the chamber rooms are communicated with each other in the form of flowing in from upper parts and flowing out from lower parts; the grille filter screen room is obliquely provided with a grille filter screen; the active sludge anaerobism room is internally hanged with a plurality of assembled filling materials bunches, and the bottom of the active sludge anaerobism room is provided with active sludge; and the biochemical degradation room is internally hanged with a plurality of assembled filling materials bunches. By adopting the mode that the water inlet is higher than the water outlet, the water naturally flows in and flows out due to the pressure difference of water level and the self-gravitation of the water, therefore, the integrated waste water treating tank has low cost, simple technology, flexible installation and low energy consumption, can be buried underground without occupying the ground, does not need power lift, does not need the management and the maintenance with special persons, can treat the water quality to achieve standards for irrigation water quality, and is suitable for each house in villages.

The invention discloses a hydro-fluctuation belt ecological repairing system. The system comprises a soil solidifying pad and a plant protection pad, wherein the soil solidifying pad is laid on a soilbody of the hydro-fluctuation belt, and the plant protection pad is laid on the soil solidifying pad and is of a three-dimensional hollow structure; and the system further comprises anchoring devicesused for fixing the soil solidifying pad and the plant protection pad on the soil body of the hydro-fluctuation belt; a plant seed layer or a plant rhizome layer is arranged between the soil solidifying pad and the plant protection pad. The invention further discloses a hydro-fluctuation belt bank slope greening protection method. The system and the method have the advantages that the ecologicalrepairing capability is better, the plant growth can be more convenient, and the construction operation can be more convenient.

The invention relates to an integrated sewage treatment device. The integrated sewage treatment device comprises a treatment device body, wherein a sewage inlet and a clear water outlet are respectively formed in two sides of the treatment device body; a cavity of the treatment device body is divided into four chambers including a grating chamber, an anaerobic chamber, bio-contact oxidation chamber and a clear water region by baffles according to the flowing direction of water flow; the four chambers communicate with one another in a bottom-inlet and top-outlet mode; a grating filter screen is arranged in the grating chamber; a plurality of combined packing strings are suspended in the anaerobic chamber and the bio-contact oxidation chamber; activated sludge is thrown in the anaerobic chamber and the bio-contact oxidation chamber; and the bio-contact oxidation chamber uses a diving aeration mode. A water inlet of the integrated sewage treatment device is higher than a water outlet of the integrated sewage treatment device, and water is fed and drained by pressure difference of liquid level of a water body and with the aid of gravitational flowing of the water body. The integrated sewage treatment device is high in treatment efficiency, low in running cost, flexible in mounting and low in energy consumption, can be buried in the ground, and does not occupy the land; the treated water can reach the primary standard of sewage discharge standard; and therefore, the integrated sewage treatment device is particularly suitable for sewage treatment in construction of small towns and sewage treatment of hospitals, catering and the like.

The invention relates to a screw thread connection structure comprising an arc-shaped cap, a thread connecting structure and a chamfer; the arc-shaped cap is positioned at the topmost end; a prism structure is arranged below the arc-shaped cap; the prism structure and the arc-shaped cap are cast into a whole body; the thread connecting structure is cast below the prism structure; the chamfer is arranged below the thread connecting structure.
