Treatment process for black and odorous sludge in black and odorous water body
The invention discloses a treatment process for black and odorous sludge in a black and odorous water body. The treatment process sequentially comprises the following steps: water body desilting: sucking out and conveying the sludge in the water body through a slurry pump; garbage cleaning: conveying sludge into screening equipment to separate garbage in the sludge, then carrying out sand and mud separation, and then enabling the screened sludge to flow into a settling pond; concentrating and settling: sequentially adding a flocculating agent and a settling agent into the settling pond to enable sludge to settle at the bottom of the settling pond to form bottom mud, pumping out liquid on the upper layer of the settling pond for purification treatment, and discharging the liquid back to the raw water body after the liquid is qualified; bottom mud hardening and tempering: pumping the bottom mud at the bottom of the settling pond to a bottom mud hardening and tempering device, and then adding a hardening and tempering agent for hardening and tempering; dehydration and drying: sending the tempered bottom mud to a dehydrator for dehydration and drying to form a mud cake. The process provided by the invention has efficient treatment efficiency and dehydration effect, and can bring better environmental benefits and social benefits.
本发明公开了一种黑臭水体中黑臭淤泥的处理工艺，依次包括如下步骤：水体清淤：将水体内的淤泥经过泥浆泵吸出并输送；垃圾清理：淤泥输送至筛分设备内将淤泥内的垃圾分离，然后进行沙泥分离再将筛分出的淤泥流入至沉淀池内；浓缩沉降：将絮凝剂和沉降剂先后投入沉淀池内，使淤泥沉降在沉淀池底部形成底泥，沉淀池上层的液体抽出进行净化处理合格后再排回原水体内；底泥调质：将沉淀池底部的底泥抽出至底泥调质装置，然后加入调质剂进行调质；脱水干化：将调质后的底泥送至脱水机进行脱水干化形成泥饼。本发明具有高效的处理效率和脱水效果，能够带来更优的环境效益和社会效益。
