What are the routine inspections at a wastewater treatment plant?

Stepping into a wastewater treatment plant is like entering a vast "city intestinal hospital." Every corner and every piece of equipment here is silently working to purify wastewater. The inspectors are the "general practitioners" of this hospital, shuttling between the pipeline jungle and the machine matrix every day, using their keen eyes, sensitive sense of smell, and professional tools to conduct a meticulous "physical examination" of the entire system. Today, let's follow the footsteps of the inspectors and see what they inspect every day at the wastewater treatment plant!

Hebei University: A novel magnetic adsorption-capacitive deionization coupled technology for industrial saline wastewater recovery

Hebei University: A novel magnetic adsorption-capacitive deionization coupled technology for industrial saline wastewater recovery

There is an urgent need for economical and efficient seawater desalination technologies for the recovery of industrial saline wastewater and the desalination of seawater and brackish water. Desalination technologies based on adsorption often suffer from low adsorbent adsorption capacity, susceptibility to pollution, regeneration difficulties, and secondary pollution.

How to solve the problem of wastewater plant influent being impacted?

How to solve the problem of wastewater plant influent being impacted?

1. Dissolved Oxygen Adjustment Strategy When the influent is subjected to high-load shock, it can cause an abnormal decrease in dissolved oxygen. In this case, the system can be stabilized and prevented from water quality fluctuations through various methods. One of them is to increase the aeration by adding air blowers to quickly control the dissolved oxygen at a higher level, so that the system can recover quickly.

Key issues and countermeasures for the treatment and resource utilization of mine water in coal mines

Key issues and countermeasures for the treatment and resource utilization of mine water in coal mines

Coal mine water is characterized by large volumes and relatively low water pollution, making it a potential source of unconventional water resources. However, the low utilization rate of coal mine water resources remains a significant challenge. This paper analyzes the key issues hindering the resource utilization of coal mine water from three aspects: water treatment technology, integrated resource utilization models, and standardization systems. For the treatment of mine water containing suspended solids, iron and manganese, high salinity, and acidity, the development directions of low-carbon and low-cost technologies are discussed and analyzed, including enhanced coagulation sedimentation and microfiltration and ultrafiltration for direct removal of suspended solids, biological iron and manganese removal, and nanofiltration membrane desalination for reuse. The characteristics and progress of sludge reduction and resource utilization technologies in the mine water treatment process are summarized. Addressing the issues of limited internal consumption and unclear external utilization pathways for coal mine water within enterprises, this paper explores an integrated resource utilization model combining internal and external enterprise utilization through centralized treatment plants. The prospects and feasibility of producing high-quality drinking water from mine water are also preliminarily analyzed. Based on clarifying the current status of the emission and comprehensive utilization standards for coal mine water, this paper proposes the establishment of specific emission standards for coal mine water and suggests supplementing technical specifications for the resource utilization and comprehensive utilization of coal mine water, sludge treatment and disposal, and resource utilization.
