Abstract

The invention discloses a wastewater treatment process which comprises the following steps of: pumping wastewater into an acid regulator, carrying out air aeration treatment on the wastewater in a neutralization tank by using an aeration device, carrying out air aeration treatment on the wastewater in a tower by using the aeration device, enabling the wastewater to flow into the neutralization tank automatically, carrying out air aeration treatment on the wastewater in the tower by using the aeration device, meanwhile, adding alkali into the tank, enabling the wastewater to automatically flowinto a DER electrolytic reaction tank, performing air aeration on the electrolytic reaction tank by using the aeration device, enabling the wastewater to enter a flocculation sedimentation tank, enabling effluent to enter a hydrolysis acidification tank, stirring the wastewater in the tank by using a submersible stirrer, enabling the effluent to enter a primary sedimentation tank, enabling the effluent to enter a water distribution tank, pumping the effluent into an IC anaerobic reactor by using a pump, enabling the effluent to automatically flow into an anaerobic sedimentation tank, enablingthe effluent to enter A/O, enabling the effluent to enter an MBR membrane reactor, enabling the effluent to enter a Fenton reaction tank, adding PAM to enable small particles to form large particles for rapid sedimentation, and enabling the effluent to enter the flocculation sedimentation tank to realize mud-water separation and supernatant discharge. The problem of wastewater treatment is fundamentally solved.

Description

technical field [0001] The invention relates to the field of electrolysis technology, in particular to a wastewater treatment technology. Background technique [0002] The principle of wastewater treatment process: micro-electrolysis is based on the galvanic reaction in electrochemistry. When iron and carbon are immersed in the electrolyte solution, since there is an electrode potential difference of 1.2V between Fe and C, countless micro-battery systems will be formed, forming an electric field in their action space. The new ecological ferrous ions produced by the anode reaction have a strong reducing ability, which can reduce some organic substances, and can also make the bis The bond is opened to decompose some refractory cyclic and long-chain organic compounds into easily biodegradable small molecule organic compounds to improve biodegradability. In addition, divalent and ferric ions are good flocculants, especially nascent ferrous ions have higher adsorption-flocculat...
