Experiments about static simulation of microbicide MN-202 and Xinjiermiing to treat recycling water in refinery have been carried out.

Analyze the origin and harm of the microorganism in circulating cooling water system,Proposed the methods of continuously adding the oxidized disinfectant sodium hypochlorite and the biology dispersing agent,And regularly adding the highly effective broad spectrum non-oxidative bactericide,Then summarized the judgments and the examination means of the medium leaking in refinery.

The overall purpose of this research was to confirm the feasibility of treating residue of circulating cooling water of refinery using dissolved air floatation process.

This paper is to study the biochemical method used in the treatment of activated sludge in refinery wastewater under the activation conditions.

The removal effects of COD,NH_3-N and turbidity from refinery wastewater in the biofilter were investigated using activated carbon,zeolite,architectural ceramic particles and engineering ceramic particles as biofilter packing.

The flocculation of composite flocculant polyaluminum chloride (PAC)—polydimethydiallyammonium chloride (DMDAAC) for the wastewater from oil refinery was compared with that of PAC or PDMDAAC.

Practicability of district heating using heat pumps with circulating water of power plant as heat source;
