Description

Glass fiber wastewater treatment equipment Technical Field The invention relates to the technical field of wastewater treatment equipment, in particular to glass fiber wastewater treatment equipment. Background Glass fiber is an inorganic nonmetallic material with excellent performance, and has the advantages of good insulativity, strong heat resistance, good corrosion resistance and high mechanical strength, but has the disadvantages of brittle property and poor wear resistance. The yarn is manufactured by taking six ores of pyrophyllite, quartz sand, limestone, dolomite, loam and boron-magnesium stone as raw materials through the processes of high-temperature melting, wire drawing, winding, weaving and the like, the diameter of a monofilament is several micrometers to twenty-several micrometers, which is equivalent to 1/20-1/5 of that of a hair, and each bundle of fiber precursor consists of hundreds or even thousands of monofilaments. Glass fibers are commonly used as reinforcing materials in composite materials, electrical and thermal insulation materials, circuit substrates, and the like in various areas of national economy. The glass fiber industry in China is in the leading world, the glass fiber production quantity is in the first place, the environment-friendly situation in China is in strict supervision on waste water and waste gas, and enterprises are promoted to adopt more advanced and efficient waste water treatment processes. The glass fiber waste water is organic waste water, and its property is related to the kinds of impregnating compound contained, mainly including lipid, emulsifying agent, water-soluble organic matter, toxic substance, small quantity of glass fiber and residue, when the glass fiber is produced, it is required to spray brightening agent made up by chemical raw materials of unsaturated polyester resin, petroleum ether and mechanical lubricating oil, etc. before cooling, and discharge it together with cooling water so as to produce milky glass fiber waste water, and can affect recovery and reutilization of resource. For such waste water, an effective method is first used to remove suspended substances, and in the prior art, some medicaments (generally called coagulants and coagulant aids) are added into water, so that particles which are difficult to precipitate in the water can be mutually polymerized to form colloid, and then the colloid is combined with impurities in a water body to form larger floccules. The flocculating constituent has strong adsorption capacity, can adsorb suspended matters, can adsorb partial bacteria and soluble substances, and is increased in volume and sunk through adsorption. However, the organic polymer particles have light specific gravity, fine particles and slow precipitation, and the precipitation method has small area loading capacity of the precipitation tank and large dosage. And the general coagulating sedimentation has an unsatisfactory treatment effect on the coagulating sedimentation. In view of the above, a glass fiber wastewater treatment apparatus is provided to solve the above technical problems. Disclosure of Invention Aiming at the defects of the prior art, the invention provides glass fiber wastewater treatment equipment, which solves the technical problems that the area load capacity of a sedimentation tank is small and the required dosage is large due to the fact that organic polymer particles in glass fiber wastewater are light in specific gravity, fine in particles and slow in sedimentation, and the rate of sedimentation filtration and the rate of aeration are reduced when the environmental temperature is reduced. In order to achieve the above purpose, the present invention provides the following technical solutions: a glass fiber wastewater treatment apparatus comprising: The device comprises a shell, wherein a device cavity is formed in the shell; the liquid inlet is arranged on the upper surface of the shell; The reaction tank is fixedly arranged in the middle of the device cavity; The fixed plate is fixedly arranged on the inner top wall of the device cavity; the motor is fixedly arranged on the upper surface of the shell; A sliding cavity is formed in the fixing plate, a first elastic air bag and a second elastic air bag are symmetrically and fixedly connected to two side walls of the sliding cavity, a third one-way valve and a fourth one-way valve are symmetrically and fixedly arranged in one side wall of the fixing plate, the third one-way valve is communicated with the outside, and the fourth one-way valve is communicated with the second guide pipe; Preferably, the liquid inlet is communicated with the reaction tank through a liquid inlet pipe, a first grating, a second grating and a third grating are inserted in the liquid inlet pipe at equal intervals, a pull rod is fixedly connected with the first grating, the second grating and the third grating together, and one end diameter of the pull rod is larger than the pi
