Abstract

The invention relates to a high-throughput capacity sewage sludge depth reducing method. The method is based on a high-throughput capacity sewage sludge depth reducing device. The high-throughput capacity sewage sludge depth reducing device comprises pressure filter plate frames, a long-stroke oil cylinder (1), a short-stroke oil cylinder (9), a mechanical amplification mechanism (10) and a high pressure sludge feeding pump (28), pressure filter chambers (37) are formed between the pressure filter plate frames, the left side and the right side of every pressure filter plate frame are respectively connected with an outer ring (32) and an inner ring (34), the outer rings (32) and the inner rings (34) of the two adjacent pressure filter plate frames closely cooperate, and every outer ring (8) is fixedly provided with a sealing member (33); and the output end of the long-stroke oil cylinder (1) is fixedly connected with a main push plate (8), and the mechanical magnification mechanism (10) is arranged between the main push plate (8) and an auxiliary push plate (11). The method has the advantages of few vulnerable parts, low energy consumption, and low water content of dehydrated sludge.

Description

technical field [0001] The invention relates to the field of sewage sludge treatment, in particular to a method for reducing the depth of sewage sludge with a large processing capacity. Background technique [0002] The high moisture content of sludge is the bottleneck that restricts sludge treatment and disposal. Sludge with high moisture content is not only bulky, but also contains a large amount of organic matter, heavy metals and harmful microorganisms that are easily corrupted or released into the environment, causing secondary pollution. Subsequent landfill, incineration and resource utilization of sludge will cause adverse effects. Therefore, sludge dehydration reduction is the primary purpose of sludge treatment, and reduction is the basis for realizing other "three modernizations" of sludge. The drier the sludge, the more beneficial it is for subsequent treatment and disposal. [0003] The commonly used dewatering equipment for early sludge includes plate and frame...
