What are the physical treatment methods for pharmaceutical wastewater?

Based on the characteristics of pharmaceutical wastewater, physicochemical treatment is required as a pretreatment or post-treatment step in its treatment process. Currently used physicochemical treatment methods mainly include coagulation, flotation, adsorption, ammonia stripping, electrolysis, ion exchange, and membrane separation. (1) Flotation Method: Flotation methods typically include various forms such as

What are the chemical treatment methods for pharmaceutical wastewater?

When applying chemical methods, excessive use of certain reagents can easily lead to secondary pollution of water bodies. Therefore, relevant experimental research should be conducted before designing the treatment. Chemical methods include the iron-carbon method, chemical oxidation-reduction method (Fenton’s reagent, H2O2, O3), and deep oxidation technology. (1) Oxidation Method This

Coking Wastewater Treatment Process:

1. A screen is installed at the inlet of the wastewater treatment system to remove large floating objects, branches, weeds, wood chips, plastic waste, and domestic garbage, protecting the safe operation of pumps and reducing the load on subsequent processes. 2. Wastewater flows by gravity into a collection tank after

What are the characteristics of coking wastewater?

distillation, purification, and by-product recovery processes of coking and coal gas production. It contains volatile phenols, polycyclic aromatic hydrocarbons, and heterocyclic compounds such as oxygen, sulfur, and nitrogen. It is a type of industrial organic wastewater with high CODcr, high phenol value, high ammonia nitrogen, and is difficult to treat.

What is the A2O treatment method?

1. AO (Anoxic-Oxic) process: Also known as the anaerobic-aerobic process, A (Anaerobic) is the anaerobic stage, used for ammonia and phosphorus removal; O (Oxic) is the aerobic stage, used for removing organic matter from the water. Its advantage is that in addition to degrading organic pollutants, it also has a

Introduction to Common Wastewater Treatment Processes

(1) According to the urban wastewater treatment and pollution prevention technology policy, wastewater treatment facilities with a daily treatment capacity of 200,000 cubic meters or more (excluding 200,000 cubic meters/day) generally adopt the conventional activated sludge process. Other mature technologies may also be used. For wastewater treatment facilities with a

What are anaerobic, anoxic, and aerobic tanks?

The A2O process primarily uses biological tanks with aeration devices, propellers (anaerobic and anoxic sections), and reflux. The channel layout is divided into anaerobic, anoxic, and aerobic tanks. An anaerobic tank is a reaction tank without dissolved oxygen or nitrates. Hydrolysis, acidification, acetic acid production, and methanation occur simultaneously to
