The invention provides a riverway channel water quality biologically-intensifying device and application thereof, belonging to the field of water treatment. The riverway channel water quality biologically-intensifying device comprises a transferring shaft and a filler area, wherein with the transferring shaft is positioned in the center of the riverway channel water quality biologically-intensifying device; the filler area encloses the transferring shaft. The riverway channel water quality biologically-intensifying device is characterized in that an upper fixed plate (3), a lower fixed plate and the transferring shaft (1) are integrated into a whole by taking the transferring shaft (1) as a center; an impeller (5) is fixed on the lower fixed plate; the filler area (4) is divided into fourregions through a grating sieve mesh (6), and biological fillers are filled in the regions. The integral riverway channel water quality biologically-intensifying device is driven to move by taking water flows as a driving force when being applied to the treatment of riverway channel water bodies, prevents the fillers from washing away by combining the fixed biological fillers with suspension fillers, can achieve the effective elimination and the synchrous denitrification of COD (Chemical Oxygen Demand), achieves the moving bed effect and also greatly enhances the mass transfer rate of nutrient substances and dissolved oxygen; and in addition, the riverway channel water quality biologically-intensifying device can carry out the treatment aiming at the pollution conditions of different water layers of riverway channels and also has the advantages of energy saving, environmental protection, low acquisition cost and operation cost, and the like.

The invention provides an electric tool rest, and relates to the technical field of numerical control machine tools. To solve the problems that a tool installed on an electric tool rest in the prior art is seriously abraded in the using process due to the slow heat dissipation, and workpiece materials are prone to being bonded to a cutting blade of the tool, the electric tool rest comprises an upper tool rest shell, a lower tool rest shell and a rotating mechanism. A plurality of tool installing positions are arranged on the outer surface of the upper tool rest shell, and a plurality of first cooling liquid pipelines are arranged in the upper tool rest shell. Each tool installing position corresponds to at least one first water outlet. The first water outlets are formed in the outer surface of the upper tool rest shell and located above the corresponding tool installing positions. A second cooling liquid pipeline is arranged in the lower tool rest shell, and a second water outlet of the second cooling liquid pipeline can be communicated with any first water inlet. The electric tool rest can cool a tool through the first cooling liquid pipelines and the second cooling liquid pipeline, and the service life of the tool is prolonged.

The invention provides a waste gas purification device and a process for a coal pulping system. The exhaust gas purification tower of this treatment system has excellent purification and treatment capacity, and the treated exhaust gas of the coal pulping system can meet the tail gas emission standard, which can significantly reduce the amount of waste water generated. The process of the invention includes: firstly collecting the waste gas through a centrifugal negative pump, then the waste gas enters the purification tower, and fully contacts the circulating liquid sprayed by the high-efficiency conical nozzle on the gas-liquid flow distributor, and the fresh liquid of the trough-type water distributor carries out Secondary absorption treatment. The absorbed exhaust gas is directly discharged to meet the emission standard. Part of the tower kettle circulating liquid is discharged to the wastewater treatment process, and part of the tower kettle circulating liquid is returned to the interior of the purification tower after heat exchange. The invention also provides an absorbing liquid used in the absorbing liquid, which has the characteristics of high efficiency, multi-function, low cost and the like.

The invention relates to a special diversion anaerobic baffled reactor, which has a plurality of advan-typetages, but is still in the experimental research period at home and abroad currently, and the relevan-typet engineering design and operation reports are extremely less. By aiming at the defect, the anaerobic baffle reactor is provided with a special diversion structure, so the large-scale sewage treatment requirement can be satisfied. The sewage anaerobic treatment is compared with the aerobic treatment, the power of about 90 percent can be saved, the amount of the survival residual sludge is only 10% of the aerobic treatment, the biochemical oxygen demand (BOD) removal rate can reach above 90%, the chemical oxygen demand (COD) removal rate is about 70-90%, most organics are converted into methane, and the special diversion anaerobic baffled reactor not only saves the energy but also produce the energy, and has a wide development prospect. The reactor is scientifically arranged and reasonably distributed, is dispensed with a triphase separator, is easy to control, is not blocked and has stable processing efficiency. The special diversion anaerobic baffled reactor can fully exert excellent features in the large-scale sewage water treatment field and can be practically applied.

The invention provides a multifunctional tool fixture. The multifunctional tool fixture comprises a supporting base, a rotating table, a turntable, a rotating wheel and a third driving device, whereinthe supporting base is composed of two supports; rotary shafts at the two ends of the rotating table are fixed to the supports correspondingly; the turntable is mounted on the rotating table, a firstdriving device mounted at the bottom of the rotating table drives the turntable to rotate, and a plurality of sliding blocks capable of moving in the radial direction and a plurality of clamping blocks corresponding to the multiple sliding blocks in position and arranged on the inner side of the edge of the turntable are arranged on the turntable around the axis of the turntable; the rotating wheel is mounted on the turntable and is coaxial with the turntable, a circle of inward concave grooves is formed in the outer edge face of the rotating wheel, cams are arranged between every two adjacent grooves, the rotating wheel is driven to rotate by a second driving device mounted at the bottom of the rotating table, and the outmost edge of the rotating wheel pushes the sliding blocks to slideoutwards and abut against the clamping blocks; and the third driving device drives the rotating table to swing or rotate along the rotary shafts of the rotating table. The multifunctional tool fixturecan improve the machining efficiency of parts and increase the product yield, the machining quality is ensured, and the labor intensity of manual operation is relieved.
