Embodiment 1
[0060] Taking the chemical sewage in the pharmaceutical manufacturing production park as an example, when it enters the device, the B / C is 0.1, the average COD is 400 mg / L, and the average ammonia nitrogen is 40 mg / L.
[0061] The sewage treatment plant processes the above-mentioned sewage through the following steps:
[0062] Step 1: The control valves of the outlet pipelines of the hydrolytic acidification pool (3) and the multifunctional biochemical pool (4) are simultaneously opened to form a parallel connection, so that the multifunctional biochemical pool is transformed into a hydrolytic acidification pool, and the sewage in the chemical industry park passes through the water inlet pump (1) in parallel Enter the hydrolytic acidification pool (3) and the multifunctional biochemical pool 4), and combine with the subsequent process to form a hydrolytic acidification-anoxic-MBR process, and the automatic control device (28) is turned on or off according to the feedback signal...

The invention provides a sewage treatment device for a chemical industry park. The sewage treatment device is a technical-combination-changeable device, is positioned in a container and comprises a hydrolysis acidification pool (3), a multifunctional biochemical tank (4), a vertical flow sedimentation tank (7), a denitrification tank (10), an aeration tank (11), an MBR reaction tank (14), an automatic control device (28) and sewage pipelines, wherein the hydrolysis acidification pool (3) is provided with a stirrer; the multifunctional biochemical tank (4) is provided with another stirrer, a closeable tank cover is arranged at the top of the multifunctional biochemical tank (4), the denitrification tank (10) is provided with another stirrer, and the aeration tank (11) is filled with fillers. The invention further provides a sewage treatment method of the device. According to the sewage treatment device and the sewage treatment method thereof, the sewage treatment device is a technical-combination-changeable sewage treatment device with strong adaptability, good effects, high flexibility and maneuverability; mass operating data can be provided, and the sewage treatment device and the sewage treatment method thereof are of greatest significance for the design and the stable operations of sewage treatment plants in the chemical industry park.
Description
technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment device in a chemical industry park, in particular to a sewage treatment device in a chemical industry park with variable process combination and a sewage treatment method thereof. Background technique [0002] At present, China's industrial economy continues to develop, and a park-based development model has gradually formed. Especially the chemical industry, which is a pillar industry of my country's economic development, is showing a trend of vigorous development of chemical parks. Correspondingly, a large amount of chemical industrial sewage generated thereby also needs to be treated urgently. In this situation, the establishment of sewage treatment plants in chemical industrial parks has become the main solution to the sewage treatment in chemical industrial parks. As a sewage collection and treatment site, its role in the prevention and control of regional wate...
