The invention relates to the technical field of oily sludge treatment, in particular to an oily sludge recycling-harmlessness comprehensive treatment process and equipment thereof.The oily sludge recycling-harmlessness comprehensive treatment process comprises the following steps that S1, dehydration treatment is conducted, specifically, firstly, impurities in oily sludge are removed and crushed through pretreatment equipment, so that subsequent treatment of the oily sludge is facilitated; s2, tempering treatment: adding a tempering agent, such as acetic acid, sodium hydroxide, hydrogen peroxide, calcium oxide, diatomite and polyacrylamide (PAM), into the sludge to improve the performance of the sludge, the addition amount of the sodium hydroxide is 0.5-5% of the dry weight of the sludge, the addition amount of the hydrogen peroxide is 0.5-3% of the dry weight of the sludge, the addition amount of the calcium oxide is 1-10% of the dry weight of the sludge, and the addition amount of the diatomite is 1-10% of the dry weight of the sludge; the addition amount of the diatomite is 1%-5% of the dry weight of the sludge, and the addition amount of the PAM is 0.01%-0.5% of the dry weight of the sludge. According to the oil-containing sludge treatment device, oil-containing sludge can be conveniently and rapidly pretreated through the arranged rotation adjusting device, so that impurities in the sludge can be fully treated.

The present application relates to sewage treatment technical field, especially to a kind of sewage treatment device of water conservancy project.The present application aims at overcoming the shortcomings that suspended solids precipitation process time is longer, and precipitate is easy to secondary pollution sewage in the process of cleaning sedimentation tank.The technical implementation scheme of the present application is: sedimentation tank, the sedimentation tank is opened in upper portion and is located in the lower portion of sewage discharge port of sewage discharge port located in its upper portion, the sedimentation tank is opened in lower portion;Rotary outer tube, the movable setting of rotary outer tube is in the bottom of sedimentation tank;Venturi tube, the outer wall of rotary outer tube is provided with venturi tube, and the venturi tube has several ones.The present application is provided with venturi tube, and venturi tube simultaneously sprays flocculating agent and air, so that flocculating agent blows air into fine bubbles, flocculating agent becomes flocculating group and adheres to pollutant and floats on the surface of sewage, while improving the efficiency of sewage treatment, it is convenient for staff to handle the pollutant adhered by flocculating group in time, thereby avoiding secondary pollution of pollutant to sewage.

The utility model discloses an efficient spiral-flow type sewage treatment precipitation device, which relates to the technical field of sewage treatment, and comprises a box body, a cyclone is arranged at the upper part in the box body, a connecting frame is connected to the upper part of the outer wall of the cyclone, the back surface of the connecting frame is connected with the box body, a water inlet is connected to the upper part of the outer wall of the cyclone, and a water outlet is connected to the lower part of the outer wall of the cyclone. And a water outlet is formed in the top of the cyclone. According to the utility model, through the arrangement of the swirler, the connecting pipe, the drain pipe, the floating plate and the like, after sewage is treated by the swirler, large-particle objects enter the storage screen frame, water flow is input into the connecting pipe through the water outlet, enters the drain pipe and is discharged to the bottom end of the inner side of the box body, and the water flow is pressed by the floating plate with certain gravity, so that the large-particle objects enter the storage screen frame; the outer wall of the floating plate is limited by the sliding block and the inner wall of the box body, so that the floating plate has the capability of quickly flattening the shaking water surface, and fine particles in water can be conveniently precipitated under the action of the gravity of the fine particles.

The utility model discloses automatic dust removal equipment for bottle cap processing, which belongs to the technical field of bottle cap processing and comprises a conveying mechanism and a bottom frame, a fixing component is arranged on the surface of the bottom frame, an electric push rod is arranged at the top of the bottom frame, an adjusting plate is arranged at the top end of the electric push rod, and a connecting frame is fixedly connected to the top of the adjusting plate. The automatic dust removal equipment for bottle cap processing has the beneficial effects that the automatic dust removal equipment for bottle cap processing can drive the adjusting plate, the connecting frame, the supporting plate and the adjusting frame to ascend and descend through work of an electric push rod, the height of the structure can be conveniently adjusted and controlled, external air can be sucked into the adjusting box through work of an air suction pump, and the dust removal efficiency is improved. And by means of a filtering frame and a filtering plate, the treated dust can be conveniently collected and treated, by arranging a sliding groove, the positions of the filtering frame and the filtering plate can be conveniently adjusted and controlled, and the dust in the filtering plate can be conveniently removed.
