Embodiment

[0029] (1) The preparation process of the device for removing refractory organic matter from petrochemical wastewater by adsorption-bioxidative degradation is as follows:

[0030] The main body of the reactor of the device is made of plexiglass plate, and the length of the pool is 105 cm, the width is 30 cm, and the height is 60 cm. The diameter of the water inlet is 1cm, and the center point of the water inlet is located on the vertical center line of the left side, and is 5cm away from the apex. The installation groove is a strip-shaped groove with a width of 3cm, which is arranged at intervals on the front and rear panels. The first installation groove from the left side is 15cm away from the left panel and is located on the rear panel. The second installation groove is 15cm away from the left panel. Surface 30cm, located on the front panel. The multifunctional adsorption plate is 45cm long, 25cm wide, and 2cm thick, and is fixed on the installation groove from the bottom ...

Abstract

The invention discloses a device for removing petrochemical engineering wastewater difficultly-degraded organic matters through adsorption-biological oxidative degradation. The device comprises a water inlet, installing grooves, a multifunctional adsorbing plate, a reactor main body and a water outlet, wherein the water inlet and the water outlet are respectively distributed in the left reactor wall and the right reactor wall of a reactor main body, two adjacent installing grooves are alternatively distributed in the front reactor wall and the rear reactor wall of the reactor main body, a distance between the installing groove at the leftmost side and the left reactor wall is 15cm; a distance between every two installing grooves in the same reactor wall is 30cm; the multifunctional adsorbing plate is arranged inside the reactor main body and arranged on the installing grooves; the width of the multifunctional adsorbing plate is 5 / 6 that of the reactor main body. The device has the beneficial effects of high efficiency, low cost and simplicity in operation when petrochemical engineering wastewater is treated.

Description

technical field [0001] The invention belongs to the technical field of petrochemical wastewater treatment, and in particular relates to an adsorption-biological oxidation degradation device for removing refractory organic matter from petrochemical wastewater. Background technique [0002] Petrochemical wastewater has the characteristics of complex composition, odor, turbidity, high concentration of organic matter and salt, strong alkalinity, and difficulty in biodegradation. Coal chemical wastewater is a typical petrochemical wastewater. In addition to dozens of inorganic substances such as ammonia nitrogen, sulfur cyanide, sulfide, and cyanide, coal chemical wastewater also contains phenols, monocyclic and polycyclic aromatics Compounds, heterocyclic compounds containing nitrogen, sulfur, oxygen, pyridine, carbazole, biphenyl and many other organic compounds are serious hazards to water bodies, aquatic plants, aquatic animals and human health. At present, the domestic trea...
