Embodiment Construction
[0024] The remaining sludge with a moisture content of more than 78% after dehydration in the urban sewage treatment plant is transported to the plant and transported to the sludge silo by a screw conveyor (Gongyi City, Henan Province Great Wall Machinery Factory) for storage. The sludge silo is a cylindrical silo (Putzmeister, Germany), with a hydraulically driven sludge carriage and a shaftless screw conveyor at the bottom to prevent sludge from agglomerating.
[0025] The sludge in the silo is sent to a stable mixing tank (Henan Hongxing Mining Machinery Co., Ltd., Zhengzhou) through a screw conveyor, and 10% of the sludge is added with CaO, and stirred for 10 minutes, which can separate and dehydrate 10% of the sludge. , can also play the role of sulfur fixation. Reduce the moisture content to 65% sludge; send the stabilized sludge to the deodorizing mixing tank through a screw conveyor (Henan Hongxing Mining Machinery Co., Ltd., Zhengzhou), and add 1.24% Fe of the sludge ...
