Description

Technical Field

[0002] Chemical waste liquid usually refers to liquid waste containing high concentrations of chemicals generated during the production process of the chemical industry. These chemicals may include organic solvents, heavy metals, toxic and hazardous substances, etc. Chemical waste liquid is characterized by high concentrations of pollutants and high toxicity, which are difficult or impossible to degrade directly through conventional sewage treatment processes. Chemical waste liquid contains various organic and inorganic substances, including solvent substances or cyclic compounds. These complex compositions make the treatment of waste liquid more difficult. When treating sewage, flocculants must first be added to settle impurities and separate flocculants from water, and then the harmful chemical components in the water must be further treated to complete the treatment of sewage so that the sewage meets the discharge standards.

After the water and flocculants are separated, there are residual flocs at the bottom of the pool. At this time, there is a large amount of water in the flocs.

After the sewage is stratified, the water pump 59 is turned on, and the flip motor 36 is turned on at the same time. The flip motor 36 drives the main connecting shaft 38 to rotate, the main connecting shaft 38 drives the main linkage gear 39 to rotate, the main linkage gear 39 drives the slave linkage gear 37 to rotate, and the slave linkage gear 37 drives the slave connecting shaft 40 rotates, and the connecting shaft 40 drives the downward pressure filter flap 33 to be in a horizontal state. The water in the upper layer of the flocculation tank 6 is sucked into the adsorption tank 7 by the water pump 59, and is then released from the drain pipe 58 after being adsorbed by the activated carbon adsorption layer 57. At this time, the buoyancy block 31, the support body 32 and the downward pressure filter flap 33 follow the water surface to drop after the water surface drops, and the downward pressure filter flap 33 presses down the flocculants. Finally, the conversion motor 44 is turned on, and the conversion motor 44 drives the conversion rotating shaft 42 to rotate. The conversion rotating shaft 42 drives the extrusion flocculant removal ball 41 to rotate, so that the flocculant holding tank 46 faces upward, and the flocculants enter the flocculant holding tank 46. Then, the conversion motor 44 is turned on again to rotate the extrusion flocculant removal ball 41, so that the flocculant holding tank 46 faces downward, and the flocculants can be separated.
