Problems solved by technology
Besides not being particularly efficient, these machines are bulky and need to be attended to
[0013] Or use centrifugation, but centrifugation also yields very low dry matter content (22-25% d.m.)

Embodiment Construction
[0030] Referring to the accompanying drawings, FIG. 1 shows sludge treatment equipment, which includes a hollow container shell 2 and an inner body 3 coaxial with the shell 2 .
[0031] Inside the housing 2, the device also comprises a compaction dewatering chamber 4, along which the sludge flows. Upstream of this chamber 4, the first end 2a of the housing 2 is provided with an inlet zone 5, which is preferably provided with a funnel for loading the sludge F to be treated; while downstream of the chamber 4, the second end of the housing 2 The second section 2b is provided with an outlet zone 6 for discharging the treated sludge out of the equipment.
[0032] The plant 1 is also provided with suitable movement means 7 , working in cooperation with the inner body 3 to facilitate the compaction of the sludge F and push it from the inlet zone 5 to the outlet zone 6 .
[0033] The filter device 10 is located inside the housing 2 and demarcates the compaction dehydration chamber 4,...

An apparatus for treating waste sludge comprises an outer container casing (2), internally hollow, an inner body (3) which is coaxial with the outer casing (2), a compacting and dehydrating chamber (4), inside the outer container casing (2) and along which the sludge to be treated runs, an inlet zone (5) for supplying the sludge to be treated to the chamber (4), an outlet zone (6) for unloading the treated sludge, movement means (7) for the sludge, cooperating with the inner body (3), which promote the compaction and advancement of the sludge from the inlet zone (5) to the outlet zone (6); the container net (11) is connected to a negative pole of a control unit to form a cathode, and at least the inner body (3) is connected to a positive pole of a control unit to form an anode. A method of treating sludge comprises the stages of promoting the continuous advancement and compaction of sludge inside a compression chamber between the anode and the cathode, and establishing a difference in potential in order to subject the sludge to be treated to an electrical field.
Description
technical field [0001] The invention relates to waste sludge dehydration treatment equipment and a treatment method thereof. [0002] In particular, the present invention can be applied to the control treatment of sludge produced in industrial production processes (such as biological tomatoes, vegetables, etc.), or the reuse of sludge produced in agricultural work or biological water purification treatment, which have previously The sludge has been treated chemically, biologically and mechanically. Background technique [0003] Industrial and / or purification processes generate large volumes of sludge solutions that include solid materials that need to be disposed of or reused. [0004] These solutions may contain sand, dirt, cellulose, residues derived from washing machines or sinks, or biodecantation sludge. [0005] Often, waste-like or reused materials are quite large in volume and weight, so it is necessary to develop solutions that reduce the volume and weight of the ...
