Abstract
The invention discloses a chemical wastewater comprehensive purification device. The device comprises a catalysis oxidation pond, an oxidation stabilization pond, a post-biochemical BAF pond, a cleanwater pond, a diluting comprehensive tank, a pretreatment primary BAF pond, a pretreatment secondary BAF pond and a water outlet pond; an ozonator is connected inside the catalysis oxidation pond through a gas pipeline, the clean water pond is provided with a water inlet hole and a water outlet hole, and the water inlet hole of the clean water pond is connected with the post-biochemical BAF pond through a rear-section transferring pipeline; the post-biochemical BAF pond comprises a pond wall, a sifting plate and an aeration channel, and suspended filler is prepared from, by weight, 60-70 partsof high-density polyethylene, 10-15 parts of polypropylene resin, 6-8 parts of low-density polyethylene, 8-10 parts of bamboo charcoal powder, 4-6 parts of wood powder, 2-3 parts of lignin, 2-3 partsof dichloromethane, 1-2 parts of guanidine, N,N-diethyl, and 0.5-1 part of N,N'-Ethylenebis(stearamide). By means of the chemical wastewater comprehensive purification device, high-salt phenolic wastewater is subjected to advanced treatment and up-to-standard drainage of the petrochemical industry at a low cost.
Description
technical field [0001] The invention relates to a comprehensive purification device for chemical sewage, belonging to the technical field of wastewater treatment. Background technique [0002] At present, the treatment methods for phenolic wastewater mainly include extraction method, adsorption method, chemical oxidation method, biochemical treatment method and so on. The extraction method consumes a lot of energy, and it is easy for the extractant to remain in the subsequent wastewater, which affects the subsequent treatment process; the adsorption method is simple to operate and is suitable for wastewater with low phenol content, but the one-time investment in equipment is large, and the regeneration of the adsorbent is difficult ; Although the chemical method can oxidize and remove phenol, the operating cost of direct oxidation is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a comprehensive purification device f...
