At an altitude of 3,100 meters, ten sets of silver-grey boxes are slowly unloaded from a flatbed truck. This is integrated sewage treatment equipment specially customized for Tibet. It will be assembled within 72 hours and will inject technological power into the treatment of domestic sewage for 20,000 local residents and more than 2 million tourists per year.

At the "nerve endings" of the urban pipe network, the integrated lifting pump station is reshaping the sewage transportation pattern with the innovation of "full integration + intelligence". This "underground heart" buried at a depth of 6-15 meters, through the coordination of grids, submersible pumps, and intelligent control systems, efficiently lifts decentralized sewage to the treatment plant, with an average daily transportation volume of over 200,000 tons, becoming the core hub of sponge city construction.

At the end of the sewage treatment plant, the belt filter press processes thousands of tons of sludge per day with a continuous process of "flocculation-pressing-stripping", reducing the moisture content from 95% to below 75%. This equipment, which consists of 127 sets of precision components, redefines the efficiency standard of solid-liquid separation through millimeter-level control and intelligent algorithms.

In the deep water area of ​​industrial wastewater treatment, anaerobic towers are reshaping the treatment paradigm of high-concentration organic wastewater with a dual-zone structure of "fluidized bed + deep purification". This cylindrical equipment with a diameter of 3-10 meters achieves a COD removal rate of more than 80% through the "biological sponge" effect of granular sludge and an intelligent circulation system. At the same time, the annual biogas production can meet 30% of the factory's electricity consumption, becoming a model of "waste treatment with waste".

At the end of the sewage treatment plant, the belt filter press is reshaping the sludge dewatering scene with "assembly line" operation. This equipment, which consists of a filter belt, a roller system and intelligent control, achieves a leap-forward reduction in sludge moisture content from 95% to 75% through a continuous process of flocculation-pressing-stripping, becoming the "efficiency champion" in the field of solid-liquid separation.

At the "throat" of the sewage treatment plant, the screen machine is protecting the safety of the entire treatment system with millimeter-level precision. This seemingly simple device intercepts dozens of tons of garbage every day through the precise arrangement and intelligent control of metal bars, becoming an indispensable "outpost guard" for water environment management.

In the wave of "zero-waste city" construction, incinerators are becoming the core equipment for urban solid waste treatment with their dual advantages of efficient reduction and energy utilization. This "industrial behemoth" that can convert garbage into heat energy has achieved a win-win situation in terms of environmental and economic benefits through intelligent control and clean combustion technology.

In the sedimentation process of sewage treatment, the inclined tube sedimentation tank has become the core equipment for efficient solid-liquid separation with its innovative design of "honeycomb structure". By shortening the particle settling path and increasing the sedimentation area, it has achieved a revolutionary breakthrough in treatment efficiency and floor space, providing an economical and efficient solution for water environment management.

In the "precision filtration" link of sewage treatment, microfiltration machines are becoming the new favorite of the industry due to their high efficiency and energy saving characteristics. This device, which looks like a drum washing machine, uses a 0.01-0.1 mm filter and an intelligent control system to accurately intercept suspended particles, providing key support for the recycling of water resources.

At the end of the sewage treatment industry chain, a device called "screw stacker" is quietly revolutionizing the way sludge is treated. Through bionic design and intelligent control, it achieves sludge reduction and harmless treatment, becoming an important equipment for water environment management.
