Global rising environmental awareness has pushed food manufacturing wastewater treatment to the forefront of industrial sustainability agendas. Effluents discharged from food production contain abundant organic substances, suspended solids and nutrients. Without proper disposal, these waste streams will cause severe ecological contamination. Driven by continuous technical upgrades from manufacturers such as Haipuou Environmental Group, the food wastewater treatment sector has witnessed remarkable technological leaps. Advanced equipment and processes not only upgrade pollutant removal capacity but also support circular resource recovery. This article elaborates on these innovative treatment technologies and shares actionable guidance for food plant operators.

一、 Advances in Biological Wastewater Treatment

（一） Practical Cases & Industry Statistical Data

A large-scale food processing factory adopted high-efficiency biological treatment equipment manufactured by Haipuou Environmental. After system commissioning, its COD removal rate rose from 75% to 90%, while ammonia nitrogen elimination efficiency increased from 80% to 95%. Industry statistics show the adoption rate of biological treatment processes for food wastewater has climbed from 60% in 2015 to 85% by 2025.

（二） Operational Recommendations

1. Match biological processes to actual wastewater composition: select anaerobic or aerobic treatment units based on pollutant concentration and discharge standards.

2. Conduct routine maintenance on bioreactors to sustain microbial vitality; test microbial activity regularly and replenish bacterial agents when necessary.

3. Fine-tune operational indicators including temperature, pH value and dissolved oxygen to maximize overall treatment capacity.

二、 Wide Application of Membrane Separation Technology

（一） Practical Cases & Industry Statistical Data

A dairy processing facility deployed Haipuou’s membrane separation system for sewage reuse. The water recycling rate jumped from 30% to 70%, drastically cutting the plant’s freshwater consumption volume. Market surveys indicate the penetration rate of membrane separation solutions in food wastewater treatment grew from 15% in 2015 to 40% in 2025.

（二） Operational Recommendations

1. Pick membrane materials with strong corrosion resistance and high flux according to wastewater pollutant characteristics.

2. Schedule regular membrane module cleaning to mitigate fouling and extend service life of filtration components.

3. Integrate pre-treatment and post-treatment units into the overall layout to guarantee stable long-term running of membrane separation systems.

三、 Digital Twin Intelligent Water Management Platforms

（一） Practical Cases & Industry Statistical Data

A comprehensive food industrial park installed Haipuou self-developed digital twin smart water system. The platform cut daily operational costs by 20% and lifted overall wastewater handling efficiency by 15%. By 2025, over half of large-scale food wastewater treatment plants have adopted digital twin intelligent monitoring technology.

（二） Operational Recommendations

1. Build precise digital simulation models by collecting and analyzing full-cycle water quality and equipment operational data.

2. Deploy IoT sensors to realize real-time water quality tracking and automatic fault early warning for rapid anomaly handling.

3. Adjust system operating parameters based on big data analysis results to optimize energy consumption and treatment performance.

四、 Deep Sludge Dewatering and Resource Reclamation

（一） Practical Cases & Industry Statistical Data

A food processing plant adopted Haipuou deep sludge dewatering machinery. The sludge volume was reduced by 80% after treatment, and the dried sludge can be recycled as organic agricultural fertilizer. Up to 2025, roughly 30% of food wastewater treatment stations have realized full deep sludge dewatering and resource recovery.

（二） Operational Recommendations

1. Select targeted dewatering machinery in accordance with sludge physical properties and daily processing load.

2. Optimize temperature and pressure parameters during dewatering procedures to improve dehydration efficiency.

3. Facilitate circular economy development by reusing dried sludge in agriculture or auxiliary industrial production.
