Embodiment Construction
[0028] use Figure 1-Figure 5 An industrial wastewater treatment process according to an embodiment of the present invention is described as follows.
[0029] Such as Figure 1 to Figure 3 Shown, a kind of industrial wastewater treatment process of the present invention, this process comprises the steps:
[0030] S1: Pass the wastewater through the filter to filter the large particles of impurities, and pass the filtered wastewater into the wastewater separation equipment; use the wastewater separation equipment to better separate the small particles of impurities from the wastewater;
[0031] S2: The equipment body of the waste water separation equipment in S1 is provided with an ultrasonic generator 26; the ultrasonic wave 26 is emitted by the ultrasonic generator, which resonates with the waste water, and the air in the waste water is separated out; after the air in the waste water is separated out, the water in the waste water Irregular movement with small particles of i...

The invention belongs to the technical field of waste water treatment, and specifically relates to a process for treating industrial waste water. The process includes the following steps: passing the waste water through a filter to filter large particles of impurities, and passing the filtered waste water into the waste water separation device; The equipment body of the separation equipment is equipped with an ultrasonic generator, and the ultrasonic wave resonates with the wastewater. After the air in the wastewater is separated, the water and small particles in the wastewater move irregularly; add sand to the ultrasonically treated wastewater, forcing The small particles of impurities in the irregular movement in the wastewater are precipitated; the wastewater filtered out of the small particles of impurities is removed for the next step of anaerobic treatment; because the air in the wastewater is separated by ultrasonic waves, the oxygen content in the wastewater is lower, which is beneficial to the follow-up For anaerobic treatment, the present invention utilizes the effect of ultrasonic waves to separate the air in the waste water, improve the filtering efficiency and save the cost.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to an industrial wastewater treatment process. Background technique [0002] With the continuous development of industry, various industrial categories are becoming more and more detailed, and the industrial wastewater produced is also diverse. The pollutants in organic industrial wastewater are complex, and most of them are toxic and harmful substances. If they are not properly treated and discharged into the water body, they will It will cause great harm to the environment. Most organic industrial wastewater contains refractory biodegradable substances and nutrients that can cause eutrophication of water bodies (such as ammonia nitrogen, etc.). The COD, ammonia nitrogen and suspended solids that still remain in water bodies using conventional biological treatment processes cannot meet the discharge requirements. , so it is necessary to add advanced processing technol...
