Cargill Grain & Oil

Background of the Project:


Cargill China is a diversified multinational corporation group, which is mainly engaged in the development, production, and sales of protein feeds and related products that use oilseeds as raw materials for processing; processing and sales of vegetable oils; development, production, and sales of high-performance starch coatings.


Project Address:

Jiangsu Nantong + Guangdong Yangjiang + Tianjin (Northern Cargill)


Wastewater Characteristics:

The wastewater from this project is mainly derived from refining wastewater, crushing wastewater, flushing surface water, domestic sewage and other wastewater. Among them, the CODcr produced by the oil refinery is the highest, and the treatment is the most difficult. The main pollutants are oils and soaps. Directly entering the biochemical treatment will cause the biochemical system bacteria and microorganisms to provide insufficient oxygen, and the microbial film will fall off. The bacterial microorganism will sustain the oil. Ability is less than 50mg/L.


Project Outcome:

1. Deliver 720m 3 /d complete sewage treatment station on time and in high quality ;

2. The use of oil separation - flotation -A / O-MBR process, effluent reaches " wastewater discharge standards " GB8978-1996 an emission standards;
