2020-12-03 01:16:22
This morning, Yang Zhiyang of Yangzhou Muyang Environmental Protection Equipment Engineering Co., Ltd. was sponsored by Shanghai Municipal Engineering Design and Research Institute, Chengtou Sewage, Shanghai Urban Drainage Co., Ltd. and China Science and Technology Association. “2010 Shanghai (2nd) Water Industry The hot topic forum gave a keynote speech and introduced a sludge concentration and dehydration technology.
The purpose of sludge dewatering and dewatering is to reduce the water in the sludge and achieve sludge reduction, creating conditions for subsequent processing, utilization and transportation. At present, the commonly used technologies for sludge concentration in China include: belt-type sludge concentration and dewatering, plate and frame filter press dewatering, centrifugal dewatering, and the like. These sludge concentration and dewatering technologies have some problems, such as easy clogging, can not be directly applied to low-concentration sludge dewatering, low automation operation, high maintenance cost, high energy consumption, secondary pollution, and unsatisfactory phosphorus removal effect.
Shepherd Environmental has developed and designed a new type of sludge concentration and dewatering equipment - the snail sludge concentration equipment, which uses the principle of screw extrusion, the strong squeezing force generated by the screw diameter and pitch change, as well as the swimming ring and fixed A small gap between the rings to achieve a new type of solid-liquid separation equipment for sludge dewatering. The snail sludge concentration equipment has the advantages of wide application range, equipment not easy to block, continuous automatic operation, saving operation cost, no secondary pollution, light body, saving engineering investment and improving phosphorus removal function.

Beeswax is obtained from the honeycombs of bees after the Honey has been removed by draining or centrifuging. The combs are melted with hot water, steam or solar heat; the melted product is filtered and cast into cakes of yellow beeswax. With detoxification, wound healing, tissue regeneration, pain relieving effect. Commonly used in the ulcer not healing, ecthyma erosion, ulceration of trauma, burn and scald.
