Urban Wastewater Advanced Treatment Engineering

To achieve higher water quality standards or enable wider reuse, Urban Wastewater Advanced Treatment Engineering is essential. Jingbo primarily uses physical or chemical methods to further purify the water after secondary treatment, removing remaining pollutants such as nitrogen, phosphorus, and difficult-to-decompose organic matter, bacteria, and viruses.

Specifically, denitrification is achieved through two biological reactions: first, bacteria convert ammonia nitrogen in an oxygenated environment, and then another type of bacteria converts it into nitrogen gas in an anaerobic environment, releasing it into the air; phosphorus removal is either accomplished by polyphosphate-accumulating bacteria that "consume" phosphorus in alternating aerobic and anaerobic environments, ultimately removing it with the sludge, or by adding chemicals to precipitate the phosphorus; filtration uses sand filters or membranes to remove fine impurities, clarifying the water; and disinfection directly kills bacteria and viruses in the water using methods such as chlorination, ultraviolet light, or ozone to prevent disease transmission. This entire process ensures the treated water can be discharged into water bodies with high water quality requirements or used for purposes such as watering plants, street cleaning, or industrial cooling.

Furthermore, Urban Wastewater Advanced Treatment Engineering inevitably generates a significant amount of sludge, which also requires proper treatment to reduce its volume, stabilize its properties, and eliminate hazards. Ideally, the sludge should also be recycled. First, the sludge is concentrated to reduce its volume; then it undergoes digestion, where microorganisms decompose the organic matter in the sludge in an anaerobic or oxygen-deficient environment. This process also produces biogas, which can be used as an energy source. Afterward, the sludge is dewatered using a centrifuge or filter press to form a sludge cake. This sludge cake has many uses, including soil improvement, landfilling, incineration, and even as a raw material for building materials.

In general, Urban Wastewater Advanced Treatment Engineering is not something to be taken lightly; it must strictly adhere to national and local environmental regulations, from design and construction to operation. It's not just about a single piece of equipment, but rather the integration of many pieces of equipment and facilities such as screens, pump stations, and biochemical tanks, along with supporting systems like electrical and automatic control systems. The core technology relies on microorganisms to "do the work," decomposing pollutants, making it particularly environmentally friendly. These projects are generally large-scale, serving an entire city or region, and are a crucial part of urban infrastructure. They must operate 24 hours a day, but parameters can be flexibly adjusted based on the volume and quality of incoming water to ensure effective treatment.

Product Advantages

The benefits of Urban Wastewater Advanced Treatment Engineering are numerous. It can fundamentally address water pollution, improving the quality of water in rivers and lakes, eliminating the black and foul-smelling conditions; the disinfection step kills bacteria and viruses, ensuring public health; cleaner water improves the urban environment and enhances the quality of life. Furthermore, the technology is quite mature; methods like the activated sludge process have been used for over a hundred years, offering high treatment efficiency, removing over 90% of many pollutants, resulting in clear treated water.

More importantly, it allows for resource recovery. The water treated by Urban Wastewater Advanced Treatment Engineering can be reused, alleviating water shortages; the biogas produced from sludge digestion can be used for power generation and heating; and even the sludge itself can be reused, truly turning waste into valuable resources. Some may think that building and operating these projects is expensive, but in the long run, it avoids many losses caused by water pollution, such as medical expenses and losses to industry and agriculture, making it extremely worthwhile. Centralized treatment is also much more cost-effective than decentralized treatment by individual households and can drive the development of environmentally related industries. Nowadays, many wastewater treatment plants are becoming increasingly intelligent, using automated machine control, requiring fewer people to monitor them. Some even utilize new technologies like big data and AI to optimize operations, resulting in greater energy savings and higher efficiency.
