Abstract
A sludge treatment device comprises an electrolytic tank made of organic glass sheets, an anodic electrode and a cathodic electrode. An anodic tank and a cathodic tank are disposed at two ends of a sludge tank of the electrolytic tank. An anodic partition net is disposed between the anodic tank and the sludge tank, and a cathodic partition net is disposed between the cathodic tank and the sludge tank. Both the anodic electrode and the cathodic electrode are made of noble metal oxide meshed titanium conductive plates and are disposed in the anodic tank and the cathodic tank respectively. Each of the anodic partition net and the cathodic partition net comprises a stainless steel mesh with an additional semipermeable membrane. One inner wall of the sludge tank is provided with a thermometer hole and a vent hole. Modified activated carbon adsorbent is disposed in the cathodic tank to facilitate adsorption of heavy metals, and accordingly reduction of content of the heavy metals in the sludge is enhanced. By electrolytic pretreatment of the sludge, the content of the heavy metals in the sludge is reduced effectively.
