The printing and dyeing wastewater was treated by a pulse cyclic fluidized bed(CFB) composite process with engineering scale of 5000m3/d.

Composite process composed of inorganic macromolecule flocculent polymeric ferric sul-fate (PFS) with leading effective microorganism (EM) was used for algae control of raw water from eutrophic water body.

The experimental method of aeration biological filter-chemical precipitation-sand filter composite process and water quality situations in experiment are introduced.

The paper introduces the different process combination and looks for the rational technological combination by comparative analysis on the basis of analyzing effects of tea factors on the quality of Meijiangcuipian tea according to the principle of tea process.

Experimental Study on Treatment of Rural Domestic Sewage by Combined Technology;

Then the incline plate sediment-continuous filtering-ultrasonic filtering-reverse osmosis combined technology was used to treat wastewater.

While gas recovery getting ito the medium and later stage,the combined technology of drainage gas recovery by gas lifting and by foam are developed in order to suit the condition of constantly descending of formation pressure.

Study on treatment of dyeing wastewater by combined process of biological micro-electrolysis;

PAC-UF combined process in the advanced treatment of water from the Yellow River;

The combined process is suitable for the wastewater treatment in city residenti.

Application and development status of activated carbon adsorption and combination processes in wastewater treatment;

Based on the study on the effects of activator and active agent on the solid caustic desulfuriza-tion, a laboratory test was performed for the combination process of solid caustic desulfurization-fixed bed sweetening for FCC naphtha refining.

, the kinetic model of combination process of residue hydrotreating and catalytic cracking is established in consideration of its features and SARA composition of residue.
