Embodiment 1
[0017] Taking the treatment of 5 tons of sewage as an example, first dissolve 15 kg of sodium hydroxide in 120 kg of industrial soft water and stir for 30 minutes, then dissolve 0.6 kg of anionic polyacrylamide in 100 kg of industrial soft water, and stir for 30 minutes. Pour sodium hydroxide solution, pay attention to dispersion, then pour 15kg of aluminum chloride, stir for 20 minutes, then pour 12kg of ferrous sulfate, pour it in evenly, pour slowly, continue stirring for a while, then slowly Pour the anionic polyacrylamide solution and stir until flocculent suspension appears.
[0018] After 1-2 days, the water stratified. The flocculent suspended matter was taken out and bagged, filtered and bagged and dumped into the garbage dump as garbage. The clean water continued to be used as water for mopping.
Embodiment 2
[0020] Taking the treatment of 10 tons of sewage as an example, first dissolve 30 kg of sodium hydroxide in 240 kg of industrial soft water and stir for 35 minutes, then dissolve 1.2 kg of anionic polyacrylamide in 200 kg of industrial soft water, and stir for 45 minutes. Pour sodium hydroxide solution, pay attention to dispersion, then pour 30kg aluminum chloride, stir for 30 minutes, then pour 24kg ferrous sulfate, pour it in evenly, pour slowly, continue stirring for a while, then slowly Pour the anionic polyacrylamide solution and stir until flocculent suspension appears.
[0021] After 1-2 days, the water stratified. The flocculent suspended matter was taken out and bagged, filtered and bagged and dumped into the garbage dump as garbage. The clean water continued to be used as water for mopping.

Abstract
The invention discloses a treatment technology of glass fiber wire drawing waste water. Sodium hydroxide and anionic polyacrylamide are respectively dissolved in a mount of water first and then are stirred for a period of time; the waste water in a sewage reservoir is stirred, a sodium hydroxide solution is slowly poured in first, and then aluminum chloride and ferrisulphas are poured in turn; after the mixed solution is stirred for a period of time, an anionic polyacrylamide solution is slowly poured in, and the stirring is continued until flocculent suspended substances appear; after the mixed solution is placed for 1 to 2 days, the waste water presents layered phenomenon, the flocculent suspended substances are fished out and processed through drainage, and then are poured into a refuse dump as trash; and the remaining water is used as the water for cleaning floor. The treatment technology eliminates paraffin, acidoid and odour in the glass fiber wire drawing waste water, reduces the COD value, has low cost, and is convenient for the treatment of glass fiber waste water.
Description
Technical field [0001] The invention relates to a process for processing glass fiber drawing sewage. Background technique [0002] The glass fiber drawing sewage contains paraffin wax and acidic substances, and the general treatment process is not thorough, mostly directly discharged, which causes serious environmental pollution. Summary of the invention [0003] The purpose of the present invention is to provide a glass fiber sewage treatment technology that can eliminate paraffin, acidic substances, and odor in the glass fiber drawing sewage, reduce the COD value, and has low cost and convenient implementation. [0004] The technical scheme for realizing the present invention is a glass fiber drawing sewage treatment process, and the specific steps are as follows: [0005] a. First dissolve sodium hydroxide and anionic polyacrylamide in a certain amount of water, and stir for a period of time; [0006] b. Stir the sewage in the sewage pond, first slowly pour the sodium hydroxi...
