The application scope of single screw dewatering machine was introduced. It not only can used in extracting black liquor but also in concentrating the pulp. In recent years, the equipment has been also used in the treatment of sludge in effluent treatment plants where there is great application potential. Furthermore the machine can also be used in tobacco field for tobacco stem and tobacco powder, pulping. These application experiences indicate the equipment has advantages including working stability, short dewatering time, high dewatering efficiency and easy operation.

The washing and bleaching were designed to use integrated technology and its equipment, such as the extrusion-diffusion replacement washing, the closed hot screening and fans defoaming etc in a reed pulp mill. Compared with the traditional black liquor extraction technology, the integration technology significantly improved extraction rate, concentration and temperature of the black liquor. It provided a practical basis for effectively optimizing the extraction of black liquor in straw pulping process.

Pulp washing is a key process to realize lower energy consumption and less effluent emission and implement cleaner production in a modern pulp mill. Nowadays it becomes difficult to select the washing device as there are various products appeared in market. According to the functional features of the devices, combing the mature operational experiences of the mills, this paper discussed the possible options among twin-roll replacement press washer, drum replacement washer and drum vacuum washer or their optimum combination as the main washing device of the modern pulp mills. The concepts of washing device configuration and washing device selection were proposed. ©, 2015, China Technical Association of Paper Industry. All right reserved.

Biorefinery was an effective way to convert biomass resources into energy and diversified valuable biomass products. It was also an effective way to high-value utilizeraw material and resource "three wastes" (waste gas, waste water and waste industrial residue). Paper industry provides an important platform for developing biorefinery. This paper emphasizes several feasible models in conjunction with traditional pulp & paper industry and biorefinery, relevant technology application and development trend. ©, 2015, China Technical Association of Paper Industry.

This paper mainly discussed the current status and application of domestic Disc Filter. This equipment is not only used for white water recovering in the paper-making stage, but also used for stock thickening in chemi-mechanical and recycled pulp process. High fiber recovery rate and low water consumption can be achieved when disc filter is used for white water recycling. It has an efficient filtration function for water recycling while it is used for stock thickening. The equipment operation is easy and reliable.
