Embodiment
[0022] (1) The preparation process of the multi-stage adsorption pond for bio-enhanced advanced treatment of coal chemical wastewater is as follows:
[0023] The multi-stage adsorption tank for biointensified advanced treatment of coal chemical wastewater is made of plexiglass plates. The main body of the reactor is 90cm long, 30cm wide, and 50cm high, and is divided into 3 spaces on average. The length of the primary baffle is 50cm, the width is 30cm, and the upper 5cm is a plexiglass screen with a mesh size of 20, which is installed at the first space dividing point. The length of the primary baffle is 50cm, the width is 30cm, and the upper 10cm is a plexiglass screen with a mesh size of 20, which is installed at the second space boundary point. Two water diversion boards are respectively located in the middle sections of the second and third spaces parallel to the baffle. The water diversion boards are 40cm long and 30cm wide and installed from the top downwards. There is ...

The invention discloses a multistage adsorption pool for the biological enhanced advanced treatment of coal chemical waste water. The multistage adsorption pool consists of a primary baffle plate, an adsorbent inlet, a secondary baffle plate, a water distribution plate, a screen mesh, a water outlet, an adsorbent outlet, a water inlet, a multifunctional adsorbent and a reactor main body, wherein the primary baffle plate, the secondary baffle plate, the water distribution plate and the multifunctional adsorbent are arranged inside the reactor main body, the primary baffle plate and the secondary baffle plate are tightly connected with the reactor main body, a space is formed at the lower part of the water distribution plate, and the multifunctional adsorbent can be freely filled between the baffle plates; the adsorbent inlet is formed in the top of the reactor main body, and the position of the adsorbent inlet is associated to the stage number of the adsorption pool; both the adsorbent outlet and the water inlet are formed in the bottom of the reactor main body; the screen mesh is installed on the wall of the reactor main body, and the water outlet is formed in the outer side of the screen mesh. The multistage adsorption pool has the beneficial effects that by adopting an adsorption-regeneration fluidized bed for the advanced treatment of the coal chemical waste water, the efficiency is high, the cost is low, the simplicity in operation can be realized.
Description
technical field [0001] The invention belongs to the technical field of coal chemical wastewater treatment, and in particular relates to a multi-stage adsorption pool for biologically enhanced 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, a...
