Typical Cases

Technologies & Innovation

Bengbu Reclaimed Water Reuse Project

Recycled water is supplied for municipal miscellaneous purposes, landscape reuse, industrial reuse, etc.; 32.85 million tons of re- claimed water can be reused annually.

Huzhou Sand Washing City Project

Water Aﬀairs Butler Project for Industrial Parks 50% resource utili- zation

Distributed PV Power Generation Project

The distributed PV systems of sewage treatment plants in Bengbu, Guzhen, Huzhou, Wuxi, Feicheng, Qixian County and Yan'an have been connected to the grid for power generation, with an installed capacity of nearly 20 MW, reducing indirect carbon emissions by about 13,000 t CO2/year.

Zero Liquid Discharge (ZLD) of Industrial Wastewater

Biochemical eﬄuent and concentrated brine are used as raw materials to produce recycled water and chemical products such as mirabilite, sodium chloride, and sodium nitrate to achieve zero discharge and resource utilization of wastewa- ter.

Aerobic Granular Sludge Technology (AGS Technology)

Advanced and low-carbon, as a "next-generation waste-water treatment technology", compared with widelyused conventional biologicalwastewater treatment tech-nologies such as A²0 and MBR. Aerobic Granular sludge(AGS) Technology can achieve efficient simultaneousnitrogen and phosphorus removal, reduce the foot-print by more than 40%, and reduce energy consumption by more than 30%.

Sludge Double Recirculation AOA Advanced Nitrogen Removal Technology

In collaboration with academicians of the Chinese Academy ofSciences (CAS),we pioneered the configuration of placing theanoxic zone at the rear, eliminating the need for internal recircu-lation and forming an anaerobic-oxic-anoxic(AOA) biologicaltreatment process.

Anaerobic membrane bioreactor

Featuring low energy consumption, high organic loading capacity, and high eﬄuent quality, it has important ap- plication prospects in the ﬁeld of sewage resource utilization.

Multivariate water quality online monitoring system based on quantum dot spectral sensing technology

By collecting the spectral characteristics of inﬂuent and eﬄuent of sewage treatment plant as well as dif- ferent process stages based on quantum dot spectral sensing technology, a mathematical model between spectral information and water quality monitoring parameter concentrations is established, and online multivariate water quality monitoring equipment is developed.

Focus on practical application and build a smart water affairs brain

In 2021,an intelligent closed-loopcontrol system for water treatmentprocess was built in Liuguangmen,Huzhou East and Guzhen SewageTreatment Plants. Based on theonline data ofinfluent as the controlbasis and the online data of effluentas the feedback correction index, itrealized the coupled intelligent con-trol of aeration, reflux, dosing andother modules, saving more than15% energy overall.
