Embodiment Construction

[0008] like figure 1 The wastewater treatment method of the shown button production process is characterized in that it adopts a combined physicochemical + biochemical treatment process; the biochemical part adopts an anaerobic-aerobic combined treatment process; Methane), the aerobic treatment process adopts the A / O process; the physical and chemical treatment process: the production wastewater and domestic wastewater enter the comprehensive adjustment pool, adjust the pH, pump it into the reaction pool with a sewage pump, add PAC and PAM to react and then enter the sedimentation tank. After the solid-liquid separation of wastewater, the flocs precipitate, and the supernatant liquid enters the biochemical treatment process; the biochemical treatment process adopts the A / O biochemical treatment method, and after the wastewater is hydrolyzed in the hydrolysis tank of the anaerobic process, part of the COD of the wastewater is removed to improve The biodegradability of wastewate...

Abstract

The invention relates to a wastewater treatment method used during button production. The wastewater treatment method is characterized by including: adopting a physiochemical+biochemical combined treatment process; adopting an anaerobic-aerobic combined treatment process for a biochemical portion, adopting an incomplete anaerobic process for anaerobic treatment, and adopting an A / O process for aerobic treatment; for the physiochemical treatment process: enabling production wastewater and domestic wastewater to enter a comprehensive adjusting tank, using a pump to pump the wastewater into a reaction tank, adding PAC and PAM for reaction, enabling the wastewater into a settling tank, and enabling supernatant to enter the biochemical treatment process; enabling the wastewater to be hydrolyzed by a hydrolysis tank through the anaerobic process to enter an aerobic section, adopting a contact oxidation process, mounting a combined filler rod in an oxidation tank, culturing microorganisms, decomposing organic matter into carbon dioxide and water, adding polymerized aluminum chloride into treated water in a mixing precipitation tank for precipitation, discharging sludge into a sludge tank for treatment, recycling outgoing water reaching standards or discharging sludge cakes to be conveyed outside for harmless treatment. The wastewater treatment method has the advantage of good wastewater treatment effect and is suitable for wastewater treatment of button production enterprises.

Description

technical field [0001] The invention relates to a wastewater treatment process. The invention is applicable to the waste water treatment process of button production enterprises. Background technique [0002] The wastewater in the button production process is mainly the polishing wastewater generated during button polishing and the wastewater discharged from the bar material machine and sheet material machine. At present, there are physical methods and chemical methods for industrial wastewater treatment at home and abroad. The removal object of physical method is insoluble suspended matter in water. The processing equipment and methods used mainly include grids, screens, sedimentation (sand settling), filtration, microfiltration, air flotation, centrifugal (swirl flow) separation, etc. The removal objects of the chemical method are colloidal substances and dissolved substances in wastewater. The main treatment methods are neutralization treatment, coagulation treatment,...
