Embodiment Construction
[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0025] Such as Figure 1 to Figure 4 Shown, a kind of fine chemical industry wastewater treatment process of the present invention, its chemical industry wastewater treatment process comprises the following steps:
[0026] S1: Chemical wastewater is collected comprehensively, physically precipitated, and filtered in order to remove surface floating debris, separate bottom sediment, and obtain clarified wastewater;
[0027] S2: Perform oxidation treatment on the clarified wastewater obtained in S1, the oxidation treatment in this step includes oxidation by ozone, and catalytic oxidation by ultraviolet rays in the aeration tank;
[0028] S3: The clarified wastewater oxidized in S2 is filtered through the first reverse osmosis to obtain reverse osmo...

The invention belongs to the technical field of wastewater purification, and specifically relates to a fine chemical wastewater treatment process. The reactor used in the wastewater treatment process includes a shell; the upper end of the shell is provided with an end cover, and the output shaft end of the centrifuge extends into the shell. And fix the No. 1 shaft; the outer ring of the No. 1 shaft is evenly equipped with a double-layer microbial injection chamber, and the No. 1 spring is installed in the horizontal direction and close to the No. The push plate is connected with the block, the microbial treatment agent is installed in the first cavity, and the second cavity is set in the horizontal direction and away from the first axis in the injection chamber; the water inlet pipe is arranged on the side wall of the shell near the end cover, There is a controller on the side wall of the lower end of the housing; the controller is used to control the work of the reactor; the lower end of the housing is provided with an outlet pipe; through the cooperation between the centrifuge, the first shaft and the injection chamber, the first Ejection of microbial treatment agent in the cavity.
Description
technical field [0001] The invention belongs to the technical field of wastewater purification, in particular to a fine chemical wastewater treatment process. Background technique [0002] The rapid development of my country's chemical industry has caused a lot of improper discharge of industrial wastewater. Industrial wastewater contains a large amount of toxic substances that not only pollute the urban environment, but also have a huge impact on people's lives, seriously threatening people's lives and health. In order to ensure the long-term development of the chemical industry and promote the further development of urban construction, it is necessary to strengthen the treatment of chemical industrial wastewater and improve the utilization rate of industrial wastewater after treatment. To ensure that the discharge of industrial wastewater meets the safety requirements, it is necessary to strengthen the control of pollution sources on wastewater discharge, and adopt reasona...
