The invention discloses an integrated treatment method for thickening, drying and purifying municipal sludge. The method comprises the steps as follows: the municipal sludge is concentrated in a sludge concentrating pool, and the concentrated submerged sludge is transported into a decanter centrifuge; a polyacrylamide cationic flocculating agent in a medicine adding box is added into the decanter centrifuge, wherein 2-3g of polyacrylamide is added into each kilogram of the submerged dried sludge, and solid particles in the submerged sludge are bonded together to form a plurality of particle groups, so that solid is separated from liquid to form a supernate and a mud cake; the mud cake is transported into a sludge treating place by a shaftless screw conveyer, and the supernate is transported to a sludge concentrating pool through a clear liquor pipeline by a water pump in a reflowing way; the supernate in the sludge concentrating pool is transported to the bottom of a filter by an overflowing groove through a pipeline; and the solid is separated from the liquid due to the centrifugal precipitation principle of the decanter centrifuge, the sludge with different charging concentrations is treated by less flocculating agent, and the physical filtering function and the physical absorbing function of the filler are abundantly acted, so that the municipal sludge and the wastewater produced by the municipal sludge can be synchronously treated.

The invention discloses an oilfield wellhead quantitative dosing device with backflow self-protection, and relates to the technical field of oilfield wellhead dosing devices, including a first housing, a first liquid medicine storage, a first transparent measuring barrel, and a first slip ring , the first electric push rod, the first displacement sensor, the first L-shaped connecting pipe, the second liquid medicine storage, the second transparent measuring barrel, the second slip ring, the second electric push rod, the second displacement sensor, the second Solenoid valve, the second L-shaped connecting pipe, the third L-shaped connecting pipe, the pipe joint and the detection spray-melting mechanism; the present invention reduces the crude oil impurities by dissolving the wax on the inner wall of the oil pipe and the mineral impurities contained in the crude oil in the oil pipe , and by detecting the first pressure sensor and infrared sensor and the first displacement sensor and the second displacement sensor in the spray-melt mechanism, the collected data in the oil pipe are collected, analyzed and sorted out to analyze and obtain the quality of crude oil.
