The installation of the biogas holder for the slaughterhouse wastewater treatment project has been completed

Address: Binzhou, Shandong

The slaughterhouse wastewater treatment project undertaken by [Company Name] in Binzhou, Shandong Province, has reached a new milestone with the completion of its 5,000 m³ biogas gas holder installation. This marks the project’s transition from main construction to equipment commissioning and trial operation.

A Robust Treatment Process for High-Strength Slaughterhouse Wastewater

Slaughterhouse wastewater typically contains high concentrations of organic matter, fats, oils, grease, and suspended solids. Its flow rate and composition also fluctuate significantly with production shifts, making it a challenging industrial wastewater stream. Located in Binzhou, Shandong Province, this project primarily treats wastewater from slaughterhouse processing operations and facility washdown.

To address these characteristics, the project employs a combined treatment process comprising pretreatment, anaerobic treatment, aerobic treatment, and advanced treatment.

Pretreatment units—including screening, grease separation, and dissolved air flotation—remove hair, feathers, fats, oils, grease, and suspended solids, reducing the load on downstream treatment stages. The core anaerobic process efficiently converts organic matter into biogas under high organic loading conditions, while substantially reducing the aeration energy required for subsequent aerobic treatment. The aerobic and advanced treatment stages further remove chemical oxygen demand (COD), ammonia nitrogen, and total phosphorus to ensure that the treated effluent consistently meets applicable discharge standards.

A 5,000 m³ Gas Holder for Reliable Biogas Storage and Supply

Biogas collection and storage are essential to the project’s resource recovery strategy. The newly installed 5,000 m³ gas holder provides buffer storage and pressure stabilization for biogas generated during anaerobic treatment.

By balancing fluctuations between biogas production and consumption, the gas holder supports a steady gas supply and enables the recovered biogas to serve as a usable energy source.
