The application discloses an ecological fishery breeding system sewage circulating treatment device, and relates to the technical field of sewage treatment.The device comprises a separation tank, a horizontal partition plate is arranged in the separation tank, and the inside of the separation tank is divided into an upper stirring chamber and a lower sedimentation chamber; a stirring mechanism is arranged in the stirring chamber, and the stirring mechanism comprises a vertically arranged stirring shaft and stirring blades arranged on the stirring shaft; the top end of the stirring shaft penetrates through the top of the tank and is connected with a driving mechanism; the bottom end of the stirring shaft penetrates through the horizontal partition plate and is rotationally connected with the horizontal partition plate; a wastewater inlet and a flocculant adding port are arranged on the top of the separation tank and are communicated with the stirring chamber; and the separation tank further comprises a drainage mechanism, which is arranged on the stirring shaft.The ecological fishery breeding system sewage circulating treatment device can promote chemical flocculation through physical stirring, can utilize an independent static space for physical sedimentation, and can automatically connect the two stages through centrifugal force, so that the efficient cooperation of physical and chemical multistage treatment is realized.

The invention discloses a resource utilization method of desulfurization waste liquid and chlorination slag, which is characterized in that carbide slag is used as a desulfurizer for desulfurization of sulfur-containing flue gas, and the generated desulfurization waste liquid is used for treatment of the chlorination slag; chlorination slag slurry and primary filter residues are obtained after the chlorination slag is subjected to dilute acidizing, thickening and filtering, and the primary filter residues are conveyed to a power plant for power generation; the method comprises the following steps of: firstly, neutralizing chlorinated slag slurry by using desulfurization waste liquid for the first time, then, adding one or more of carbide slag, lime or caustic soda for the second time of neutralization to enable the pH value of the chlorinated slag slurry to be 7-8 to obtain neutralized slag slurry, finally, filtering the neutralized slag slurry to obtain secondary filter residues and secondary filtrate, and adding cement and gravel into the secondary filter residues to prepare concrete blocks. The secondary filtrate is sent to a sewage purification system to be treated and then reused to a dust collection slag washing procedure and a concrete block preparation procedure; the method not only scientifically treats the desulfurization waste liquid, but also realizes resource utilization of the chlorination slag, and reduces the treatment cost of the desulfurization waste liquid and the chlorination slag.

The application relates to the technical field of tailing treatment, in particular to a high-mudding copper-nickel ore dressing tail water treatment, recycling and recycling system and process, wherein the high-mudding copper-nickel ore dressing tail water treatment, recycling and recycling system comprises a crushing module, a grinding module and a flotation module; after minerals are separated from ore slurry, the flotation module is used to obtain flotation tailings and flotation concentrates, and the flotation tailings and the flotation concentrates are respectively transported to an A-type water treatment submodule and a B-type water treatment submodule; the A-type water treatment submodule is used to receive the flotation tailings, and sequentially passes through a sedimentation unit and a dosing unit to carry out solid-liquid separation and water purification treatment; overflow water obtained through the treatment is used as A-type clarified water and is returned to the crushing module, the grinding module and the flotation module to supply water; and bottom flow water obtained through the sedimentation is transported to a tailing pond to carry out natural sedimentation, so as to recycle C-type clarified water to supply water to the flotation module. According to the application, the comprehensive recycling utilization rate of the ore dressing tail water is improved by combining tailing three-stage series deep clarification and tailing pond backwater reuse.

The utility model discloses a kind of silicon powder recovery devices in industrial silicon furnace flue gas, including equipment base, separator tank, smoke inlet and gas outlet, the inside of the separator tank is movably connected with multiple groups of adjusting mechanism for changing flue gas flow rate, the adjusting mechanism includes fixedly connected on the inner side wall of separator tank fixed pivot, the fixed pivot is movably connected with spoiler through fixed link, and the spoiler is in conformity with the inner diameter of separator tank, the end of the spoiler is movably connected with piston;Through fixed link and the spoiler of pivot connection, and piston is movably connected with the end of spoiler and penetrates tank body, when flue gas quantity is larger and flow rate is too fast, tank pressure rises and pushes piston to move out, drives spoiler to rotate to tank wall, expands flue gas flow range to reduce flow rate, prolongs flue gas residence time, makes silicon powder fully settle.
