Research and application of flocculation technology in the chemically enhanced primary treatment process, the biologically enhanced primary treatment process, and the chemical-biological flocculation process are introduced respectively.

Bioflocculation intensified primary treatment technology was characterized by followings: without the addition of medicament, smaller quantity of sludge yielded compared with chemical flocculation technology, with little aeration to restore the activity of sludge, and low cost in operation.

The paper describes technical characteristice process and engineering practice of the intensive primary physicochemical method by using EWP high efficiency wastewater purifier to treat domestic sewage in cities.

The performance of microbe preparation bio-augmentation(MPB) and compost treatment with manure(CTM) was compared.
