Embodiment Construction
[0022] (1) The preparation process of the adsorption-regeneration fluidized bed for advanced treatment of coal chemical wastewater is as follows:
[0023] The main body of the reactor is made of stainless steel. The diameter of the upper bottom of the flat top cone at both ends of the reactor main body is 15cm, the lower bottom is 30cm, the waist length is 25cm, the hollow cylinder in the middle is 30cm in diameter, and the length is 120cm. The arc is calculated from the vertical center line, 45° left and right, and the opening length is 10cm. The water inlet has a diameter of 10cm and a length of 15cm. It is located on the upper part of the flat-topped cone at the front end of the reactor main body, and the distance from the oblique line of the upper bottom is 3cm. The connecting pipe is divided into two parts, the horizontal connecting pipe and the vertical connecting pipe. The diameter of the longitudinal connecting pipe is 10cm and the length is 25cm. 2cm, 5cm in diameter...

Abstract
The invention discloses an adsorption-regeneration fluidized bed for deeply treating wastewater of a coal chemical industry. The fluidized bed is composed of a water inlet, multifunctional adsorbents, a separation bucket, a connection pipe, a water outlet, a rotary shaft, a fan blade and a rector main body, wherein the rector main body is composed of a front flat cone, a middle hollow cylinder and a rear flat cone; an opening is formed in the upper part of the front section of the hollow cylinder and the water inlet is located at the front end of the outer part of the rector main body; the connection pipe is located at the rear end of the outer part of the reactor main body; the multifunctional adsorbents, the rotary shaft and the fan blade are arranged in the rector main body; the fan blade is located on the rotary shaft and can rotate along the rotation of the rotary shaft; the multifunctional adsorbents and a water flow move in the reactor main body; the separation bucket is connected with the connection pipe; a bottom outlet of the separation bucket is connected with the opening of the reactor main body; the water outlet is located on a lower part water collection region of the separation bucket. The adsorption-regeneration fluidized bed has the beneficial effects that the efficiency is high, the cost is low and the operation is simple when the adsorption-regeneration fluidized bed is used for carrying out deep treatment on the wastewater of the coal chemical industry.
Description
technical field [0001] The invention belongs to the technical field of advanced treatment of coal chemical wastewater, and in particular relates to an adsorption-regeneration fluidized bed for advanced treatment of coal chemical wastewater. Background technique [0002] Coal chemical wastewater has the characteristics of complex composition, turbid smell, high concentration of organic matter and salt, strong alkalinity, and difficult biodegradation. In addition to dozens of inorganic substances such as ammonia nitrogen, thiocyanide, sulfide, and cyanide, coal chemical wastewater also contains phenols, monocyclic and polycyclic aromatic compounds, and heterocyclic compounds containing nitrogen, sulfur, and oxygen. , pyridine, carbazole, biphenyl and many other organic compounds, which are seriously harmful to water body-aquatic plants-aquatic animals and human health. At present, the domestic treatment technology of coal chemical wastewater mainly adopts biochemical method, ...
