Problems solved by technology
However, for some water systems with high organic matter content and colloid formation, the surface of the particles has negative charges, so that anionic and non-ionic polymer coagulants cannot capture particles with high surface potential and cannot meet the treatment requirements. The research, development and use of cationic coagulants have been paid more and more attention by people

Embodiment
[0027] A kind of performance test method that the present invention is used to process the flotation agent of oily waste water, its concrete steps are as follows:
[0028] (a) Add a certain amount of flotation agent into a beaker filled with simulated waste water, and pour it into the simulated air flotation device after stirring evenly;
[0029] (b) feed the air of a certain pressure to the simulated air flotation device, and carry out the air flotation process;
[0030] (c) Pour the floating flocs in the air flotation device into an empty beaker quickly and weigh them;
[0031] (d) dry quantitative filter paper to constant weight, take out and weigh after cooling;
[0032] (e) filter the collected floating flocs with filter paper weighed to constant weight in step (d), dry until constant weight, then cool and weigh;
[0033] (h) Calculate the floc floating rate according to the measured data, and analyze the performance of the flotation agent according to the floc floating...

The invention discloses a performance test method of a flotation agent for treating oil-containing wastewater. The method comprises the following steps: adding the flotation agent to simulated wastewater, and stirring, pouring the resulting mixture into a simulation air flotation device; carrying out an air flotation process; rapidly pouring the floating floc in the air flotation device into an empty beaker and weighing; drying quantitative filter paper to a constant weight, taking the paper, cooling and weighing; filtering the collected floating floc, drying, cooling and weighing; calculating the floc floating rate according to the tested data, and analyzing the performance of the flotation agent according to the floc floating rate; and the like. According to the present invention, with testing the floc floating rate of the flotation agent, the performance of flotation agent and the sewage treatment effect of the flotation agent are analyzed, the test time is short, the test precision is high, and the test cost is reduced.
Description
technical field [0001] The invention relates to a performance testing method of a flotation agent used for treating oily waste water. Background technique [0002] Among many urban sewage and industrial wastewater, oily wastewater from the petroleum industry is the most representative. Oilfield oily wastewater mainly comes from onshore and offshore oil extraction, processing, transportation (accidents and drainage), and industrial drainage. Oil pollutants form an oil film on the water surface, which isolates the atmosphere from the water surface and destroys the oxygen-enriched conditions of the water body. The reduction of dissolved oxygen in the water will cause the plankton in the water body to suffocate and die due to lack of oxygen; it will also limit the growth of algae and other aquatic plants. Photosynthesis affects the self-purification of water bodies; oil pollutants attach to the surface of soil particles, forming an oil film in the soil, making it difficult for ...
