Wastewater Treatment Technology

Chemical Dosing System
A chemical dosing system is an integrated equipment designed for the precise dosing, mixing, liquid transfer, and automated control of chemicals. It is widely used in circulating water systems requiring the addition of corrosion inhibitors, scale inhibitors, and biocides for water quality treatment.

Aeration and oxygen supply should be relatively simple for experts, and mainly involves three items: calculation of aeration volume (which has a lot to do with water quality and water volume), aeration fans and aeration devices. There are many methods to calculate aeration volume, each method has its own advantages and disadvantages (mainly simplicity and deviation rate). Everyone can choose a method according to the project situation and their own needs.

A2/O process is the abbreviation of Anaerobic-Anoxic-Oxic, which is the abbreviation of anaerobic-anoxic-aerobic biological denitrification and phosphorus removal process. The treatment efficiency of this process can generally reach: BOD5 and SS are 90% to 95%, total nitrogen is more than 70%, and phosphorus is about 90%.

The biofilm method is an artificial enhancement of the soil self-purification process. It mainly removes soluble and colloidal organic pollutants in wastewater, and also has a certain nitrification ability for ammonia nitrogen in wastewater. The biofilm method is widely used in the treatment of industrial wastewater.

The oxidation ditch process, as a mature activated sludge sewage treatment process, has been widely used throughout the country.

The A/O process was produced in the 1970s. Because it has the functions of degrading organic matter and denitrification at the same time, and is easy to operate and manage, it has been widely used. Since the sewage treatment process is determined based on many factors such as the amount of sewage, water quality, effluent requirements and local actual conditions, small and medium-sized urban domestic sewage treatment stations generally use A/O and other processes.

In recent years, the wastewater treatment industry has undergone significant transformations, driven by advancements in intelligent technologies such as the Internet of Things (IoT), big data, and artificial intelligence (AI). These technologies have allowed for enhanced automation, real-time monitoring, and more efficient management of wastewater treatment processes, leading to significant improvements in operational efficiency and energy savings.

The sedimentation tank is a commonly used device in the water treatment process. Its main function is to make the solid particles in the water settle to the bottom of the tank through gravity, achieving water purification. Sedimentation tanks are widely seen in diverse water treatment systems, including tap - water treatment, sewage treatment, and industrial wastewater treatment.

Water pollution is the focus of discussion in today's society. In order to make industrial wastewater reach the discharge standard, many factories have used sewage treatment equipment.
