1. Reasons for excessive total phosphorus 1. Total phosphorus in purified water is too high (water inflow is unstable) 2. Phosphorus accumulating bacteria in the aerobic section cannot absorb a large amount of soluble phosphorus, resulting in poor sludge discharge and unsatisfactory sedimentation effect. Increasing the reduction potential of the secondary settling tank increases, resulting in the release of phosphorus, and the phosphorus removal effect will be unsatisfactory, and the total phosphorus will exceed the standard. If the sludge concentration is high, increase the sludge discharge. 2. Solution to total phosphorus exceeding the standard 1. Add phosphorus removal agent at the back end to solve it. After biochemical treatment in domestic sewage plants, phosphorus generally exists in the form of orthophosphate. Iron salts, aluminum salts, phosphorus removal agents, etc. have all effects on phosphorus Great removal. 2. Adjust the biochemical treatment effect and improve the biochemical removal rate by adjusting a series of factors such as microbial nutrient ratio, DO value, and sludge concentration. 3. Add sewage treatment process equipment to further treat total phosphorus. 4. Suggestions for micro-point environmental protection In general, there are three solutions to the excessive total phosphorus, which need to be selected according to the actual situation. The latter two methods are complicated to operate and cost high, and are suitable for high-concentration total phosphorus treatment. Phosphorus agent saves cost and is easy to operate. It is suitable for removing medium and low concentrations of total phosphorus. Generally, the previous two methods cannot completely reduce phosphorus to the standard, so it should be used together with phosphorus removal agent.

The Role of Water Quality Sensors in Disinfecting Drinking Water

Water is a precious resource, and ensuring its safety for consumption is of paramount importance. With the growing concerns about water contamination and the spread of waterborne diseases, the need for effective disinfection methods has become increasingly significant. In this article, we will explore the role of water quality sensors in disinfecting drinking water and how they are revolutionizing the way we monitor and treat water quality.

Dissolved oxygen (DO) is a crucial parameter in water bodies and plays a vital role in supporting aquatic life. It refers to the amount of oxygen gas dissolved in water, and its concentration is directly related to the overall health and quality of the ecosystem. Aquatic organisms, such as fish, plants, and microorganisms, depend on adequate dissolved oxygen levels for their survival and metabolic processes. Monitoring dissolved oxygen levels is essential for assessing water quality, identifying potential pollution sources, and evaluating the effectiveness of water treatment and conservation efforts.

The Importance of Accurate Dissolved Oxygen Measurements

Accurate dissolved oxygen measurement is crucial in environmental monitoring to obtain reliable data for scientific research, regulatory compliance, and integrated water resources management. Traditional methods of dissolved oxygen measurement, like the Winkler titration method, are time-consuming, require extensive laboratory work, and may not provide real-time results. This limitation led to the development of dissolved oxygen sensors, also known as dissolved oxygen meters or probes, which enable continuous and precise monitoring of dissolved oxygen levels in the field.

How Do Dissolved Oxygen Sensors Work?

Dissolved oxygen sensors typically utilize an electrochemical measurement technique. They consist of a sensing element with a cathode and an anode, separated by an electrolyte. When the oxygen in the water diffuses through a gas-permeable membrane covering the cathode, it interacts with an electrolyte to produce a current proportional to the oxygen concentration. This current is then converted into a dissolved oxygen reading displayed on the sensor or transmitted wirelessly to a data collection system. Advanced sensors may also incorporate temperature and pressure compensation features to enhance accuracy.
