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 a comprehensive treatment method for copper smelting smoke dust and black copper sludge. The comprehensive treatment method for the copper smelting smoke dust and the black copper sludge includes: preforming high temperature smelting on the black copper sludge, the arsenic-containing smoke dust and sodium sulfate which are mixed evenly to obtain a melt, and layering the melt after cooling, thereby obtaining a mixed material containing arsenic and natrium on the upper layer and crude copper on the lower layer, wherein the crude copper can be used for electrolytic refining of copper. The comprehensive treatment method for the copper smelting smoke dust and the black copper sludge achieves synergistic treatment for the copper smelting smoke dust and the black copper sludge, is short in technical process and simple to operate, and improves recovery rate of resources.

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.

Embodiments of the present invention relate to a message synchronization method, apparatus and system. The method includes: obtaining a first sending time stamp transmitted on a main link and a second sending time stamp transmitted on a backup link respectively; calculating to obtain a time difference according to the first sending time stamp and the second sending time stamp; adding bytes to the first message transmitted on the main link and the first message transmitted on the backup link, and form second messages to be transmitted on the main link and the backup link respectively; and sending the second messages to a receiving end on the main link and the backup link respectively. According to the message synchronization method, apparatus and system provided in the embodiments of the present invention, when errors occur in the second message on the main link and are uncorrectable, the receiving end may receive the second message through the backup link, modify a second receiving time stamp on the backup link according to the time difference in the second message, so that the receiving end may obtain the same receiving time stamps on the main link and the backup link, thereby implementing the synchronization process of the messages.
