Photo-Fenton Advance

Photo-Fenton: Adding "a beam of light" to Fenton oxidation, enabling iron to self-cycle, thereby facilitating the treatment of refractory industrial wastewater.

Across multiple industries nationwide (petrochemical / petroleum / pharmaceutica

Pilot-scale to full-scale implementation (10 to 32,000 m³/d)

Photo-Fenton is an advanced oxidation process (AOP) that introduces ultraviolet or solar light on the basis of the classic Fenton reaction (Fe²⁺/H₂O₂). Through photochemical reduction of Fe³⁺, iron ions are continuously cycled back to Fe²⁺, thereby substa

Sequencing Batch Rea

SBR (Sequencing Batch Reactor): A single tank completes the full cycle of "influent feeding—aeration—sedimentation—effluent discharge" in a time-sequential manner, offering a highly flexible option for industrial wastewater treatment at small to medium fl

Across multiple industries nationwide (pharmaceutical / petrochemical / brewery

Pilot-scale to full-scale engineering (from tens to tens of thousands of m³/d)

Sequencing Batch Reactor (SBR) completes five operational phases—filling, aeration, settling, decanting, and idle—in a time-sequenced manner within a single reactor tank, eliminating the need for a secondary clarifier and sludge return. Solid-liquid separ

Nanoscale Zero-Valen

Nanoscale Zero-Valent Iron (nZVI) Reduction Technology: One Sheet of Nano Iron Reduces and Detoxifies Hexavalent Chromium, Chlorinated Organics, and Dyes in a Single Step

Multiple industries nationwide (electroplating/leather making/chemical/electroni

Pilot to full-scale engineering (tens to tens of thousands of m³/d)

Nanoscale zero-valent iron (nZVI) uses Fe⁰ elemental particles to directly reduce hexavalent chromium to trivalent chromium, dechlorinate chlorinated organic compounds, and detoxify nitro/azo dyes through reduction. It serves as a highly efficient pretrea

Oxidation Ditch…

Oxidation Ditch: An industrial wastewater treatment process that packs "extended aeration + simultaneous denitrification" into a single ring-shaped channel

Multiple industries nationwide (food/beer/soy sauce/paper/vinylon/bleaching and

Pilot to full-scale engineering (thousands to hundreds of thousands of m³/d)

The oxidation ditch is a ring-shaped ditch-type activated sludge process that combines plug-flow and completely mixed characteristics, achieving simultaneous nitrification-denitrification through extended aeration and dissolved oxygen gradients. Based on

$Nanofiltration (NF): Letting monovalent salts pass through while retaining divalent salts and dyes — the intermediate force in industrial wastewater fractionation and resource recovery.$

Nanofiltration (NF)

Nanofiltration (NF): Letting monovalent salts pass through while retaining divalent salts and dyes — the intermediate force in industrial wastewater fractionation and resource recovery.

Multiple industries nationwide (coking / printing and dyeing / coal chemical / h

Pilot to full-scale (1 to several thousand m³/d)

Nanofiltration (NF) has a pore size of approximately 1 nm and a molecular weight cut-off (MWCO) of 200–2000 Da, positioning it precisely between Ultrafiltration and Reverse Osmosis: it retains SO₄²⁻ and medium-molecular-weight organics while allowing NaCl

UASB Anaerobic Biolo

UASB Upflow Anaerobic Sludge Blanket: no aeration, no chemicals, "eating" high-strength organic wastewater into biogas — the signature reactor of anaerobic granular sludge

Nationwide multi-industry (alcohol/starch/soy products/printing and dyeing/paper

Pilot to engineering scale (1 to several thousand m³/d)

UASB relies on a self-immobilized granular sludge layer of 0.1–0.5 cm at the bottom, allowing wastewater to flow upward through it, where organic matter is broken down into methane by a four-stage anaerobic bacterial consortium in relay. The design volume
