A pre-control method of head and tail shapes of continuous casting slab for reducing the removed amount from the head and tail of hot-rolled intermediate slab. By a pre-control cutting process for the head and tail shapes of continuous casting slab, the slab is cut into a shape such that its head end surface dents inwards and its tail end surface extrudes towards outside of the slab. In the pre-control cutting process, the head and tail shapes of the slab is cut in accordance with the curve which is linearly symmetrical with respect to the width center of the slab, and the arch height (i.e., the maximum value of the denting portion of the head or the extruding portion of the tail) is controlled in the range of 0 mm to 50 mm. In such a manner, the length of the non-uniform deformation portions of the head and tail of the intermediate slab can be significantly reduced, and thus the reduction of the removed amount from the head and tail of hot-rolled intermediate slab is achieved.

The invention discloses a vortex type solid-liquid diversion purification device and a sedimentation tank provided with the same. The purification device is formed by arranging at least one group of sedimentation parts, wherein each sedimentation part comprises a guide plate and a plurality of wing plates; each wing plate is divided into a first wing plate body used for guiding sediment and a second wing plate body used for guiding a fluid in a fluid flow direction; a first flow blocking plate and a second flow blocking plate which are used for blocking fluid washing are arranged at an inlet end and an outlet end of the first flow blocking plate respectively; a hydrostatic area is formed between the first flow blocking plate and the second flow blocking plate; a sewage discharge channel is formed in a position, located in the hydrostatic area, of the first wing plate body; the first wing plate body and the second wing plate body have inclination angles, so that sediment can flow into the sewage discharge channel conveniently; a vortex area which enables the fluid to form a vortex is arranged on the second wing plate body in the fluid flow direction; and a flow collection channel allowing the fluid to pass through is formed between the vortex area and the hydrostatic area. According to the vortex type solid-liquid diversion purification device and the sedimentation tank provided with the same, the purification efficiency and the purified water quality are improved greatly, and the cost is saved.

The invention discloses a transverse distribution lamella purifier and a settling pond with the same. The transverse distribution lamella purifier is formed by arranging multiple settling modules. Each settling module comprises a guide plate, a plurality of wing plates arranged in a flow direction of fluid, a first flow baffle and a second flow baffle, wherein the first flow baffle and the second flow baffle are arranged in the front and rear of the guide plate respectively. The inlet end of each wing plate is connected with the corresponding first flow baffle, and the outlet end of each wing plate is connected with the corresponding second flow baffle. The wing plates include first and second wing plates divided along the flow direction of the fluid, the first wing plates disposed inside the settling modules are used for guiding sediment, and the second wing plates projecting out of the settling modules are used for guiding the fluid. A sediment flow passage is formed between one side of each first wing plate, close to the corresponding guide plate, and the corresponding guide plate, and the wing plates are inclined so that the sediment can flow into the passages easily. Compared with the existing settling pond having the same size, the settling tank has the advantages that purifying efficiency is more than tripled, production cost is reduced greatly, and purifying efficiency is improved significantly.

The invention relates to an A2 / O-MBR composite processing system and method based on efficient utilization of carbon source, and belongs to the technical field of sewage treatment. The A2 / O-MBR composite processing system based on efficient utilization of carbon source mainly comprises an anaerobic tank, a first anoxic pond, an aerobic tank, an oxygen elimination tank, a second anoxic pond, and a membrane pool, wherein the anaerobic tank is connected with the first anoxic pond, the first anoxic pond is connected with the aerobic tank; the aerobic tank is connected with the oxygen elimination tank; the oxygen elimination tank is connected with the second anoxic pond; and the second anoxic pond is connected with the membrane pool. The A2 / O-MBR composite processing system and method based on efficient utilization of carbon source are aimed for requirements of enhanced nitrogen removal of high discharge standard municipal sewage treatment plant; the efficient utilization of carbon source and the enhanced nitrogen removal are achieved by adding the oxygen elimination tank and the anoxic ponds in the conventional A2 / O and MBR composite technology system, and using the oxygen elimination tank to remove the adverse effect of the dissolved oxygen to the technology denitrification in the backflow nitrified liquid, and completely using the inner source nitrification effect of the anoxic pond. The A2 / O-MBR composite processing system and method based on efficient utilization of carbon source have the advantages that the utilization ratio of carbon source is high, the effect of denitrification and dephosphorization is good, the water quality of the discharged water is good, the ability to resist impact load is strong the effect of saving energy and reducing consumption is obvious, and the like.
