This utility model relates to a combined integrated wastewater deep treatment equipment, comprising: an anaerobic tank, effluent from the anaerobic tank being connected to an anoxic tank, effluent from the anoxic tank being connected to an aerobic tank, a suspended sedimentation separation structure within the aerobic tank, an aeration device below the sedimentation separation structure within the aerobic tank, supernatant from the sedimentation separation structure being connected to a vertical flow sedimentation tank, supernatant from the vertical flow sedimentation tank being connected to a gradient filtration device, and effluent from the gradient filtration device being connected to a clear water tank. The beneficial effects are: the proportion and sequence of anaerobic, anoxic, and aerobic processes can be adjusted according to different usage scenarios; the process is arranged in the order of anaerobic, anoxic, and aerobic, mainly for simultaneous nitrogen and phosphorus removal; the biological treatment zone consists of anaerobic + anoxic + aerobic; and the sedimentation zone and gradient filtration are connected in series at the end of the biological treatment zone, highly integrating biological and deep treatment processes, resulting in equipment with high treatment efficiency, high flexibility, strong adaptability, low operation and maintenance difficulty, and low operating energy consumption.

The invention relates to a method for constructing an integral sinking underground permanent wall body by taking soil in a wall. The method comprises the following steps: prefabricating an underground permanent wall body with an open hole in the middle on the ground; the underground permanent wall body sinks, and soil taking equipment is synchronously used for taking soil in the holes of the underground permanent wall body till the underground permanent wall body sinks to the designed elevation; and filling core grouting concrete into the holes of the underground permanent wall body. The prefabricated underground permanent wall body is matched with the soil taking equipment to achieve sinking while taking soil, disturbance to surrounding soil is small, safety is high, the underground permanent wall body is used for replacing a supporting pile or wall and an underground permanent structural wall which is cast in situ after excavation, holes are formed in the middle in advance, and materials and engineering cost are greatly saved; overall prefabrication is conducted on the ground, and the stress performance and the waterproof performance are good; a foundation pit does not need to be excavated before construction, soil in the wall body can be excavated under the condition of no rainfall after the wall body sinks to the designed elevation, underwater bottom sealing is carried out after the wall body is excavated to the designed elevation, and the influence on the surrounding environment is small.

The invention discloses a metal particle waste screening device, and relates to the technical field of metal recycling, the metal particle waste screening device comprises a screening box and a disc-shaped primary screening box, the primary screening box is installed on the screening box, and a primary screening mechanism is arranged on the primary screening box and used for screening out iron particles in metal particle waste; the end, away from the primary screening box, of the screening box is provided with a water flowing opening and connected with a water guiding plate, a water collecting tank is installed on the outer wall of the screening box and located below the water guiding plate, and the outer wall of the bottom of the screening box is connected with a plurality of supporting legs. The water flow applies rightward force to the metal particles, the metal particles move rightwards while sinking, the copper particles and the aluminum particles are the same in particle size but large in density difference, the sinking speed of the copper particles in the water is higher than that of the aluminum particles, the rightward moving distance of the aluminum particles in the sinking process is larger, and therefore the metal particles are prevented from sinking. And screening of the copper-aluminum particle waste is achieved.

The invention discloses a sinking and floating auxiliary cleaning platform and method, and aims to overcome the defects that a quartz product is easy to collide with the edge of a pickling tank during pickling operation, and an acid solution is easy to fill into a glove during operation by a worker. A sinking and floating switching cavity is formed in the sinking and floating platform, a through-flow hole is formed in the bottom of the sinking and floating platform, a high-pressure inflation nozzle is arranged on the sinking and floating platform, the sinking and floating switching cavity is communicated with an exhaust pipe, a switching valve is installed on the exhaust pipe, and the through-flow hole and the high-pressure inflation nozzle are both communicated with the sinking and floating switching cavity. In the pickling process, the quartz product is placed on the sinking and floating platform, the quartz product automatically sinks and floats along with the sinking and floating platform, collision of the quartz product is reduced, acid liquor is prevented from entering gloves of staff, and the labor intensity and the safety risk of the staff are reduced.
