    摘要: The present disclosure provides a water floating object treatment device for sewage treatment, including water pump, motor, round box, butt joint hole, liquid inlet pipe, electric adjusting valve, pneumatic controller, round frame, slurry pump, round tube, three-blade long plate, fan-shaped scraping plate, fine screw rod, guide sliding rod, wire brush bristle, assembling hole, fine-hole filter plate, strip hole, round plate, air cylinder, rubber round block, fan-shaped hole, threaded hole, and sliding hole. The present disclosure is reasonable in design, and function of filtering water in a treatment tank is realized. By replacing and installing the fine-hole filter plates with different sizes of holes, different degrees of filter effects are achieved. Meanwhile, the filtered water can be injected into corresponding treatment tank.

    摘要: The present invention is related to a polyurethane dispersant and a preparation method thereof. The polyurethane dispersant is terminated by a nitrogen-containing heterocyclic compound during synthesis. The nitrogen-containing heterocyclic compound is prepared by subjecting anhydride and a compound containing a primary amine and a secondary amine or a hydroxyl or mercapto group to dehydration condensation. The condensed product is the nitrogen-containing heterocyclic compound, containing a reactive hydrogen. The structural formula of the compound containing the primary amine and the secondary amine or hydroxyl or mercapto group is shown as follows: wherein n=1 to 5, and preferably 2 to 4, R1 and R2 are respectively alkyls containing 1 to 8 carbons, R1 and R2 are independent of each other or connected by a chemical bond to form one or more saturated or unsaturated 4-member to 8-member rings, and X represents N, O, or S.
