The utility model discloses a coal mine roadway car wash pool relates to car wash pool technical field, it includes setting in the car wash pool of roadway inner terrace surface, the car wash pool one side is equipped with the water inlet pipe, the car wash pool other side is provided with the drain pipe, the car wash pool inner terrace surface is the concrete terrace, and the concrete terrace bottom end is the concrete cushion, and is provided with metal anchor rod and anticorrosion anchor cable reinforcement on the concrete cushion. This kind of coal mine roadway car wash pool, vehicle drives to car wash pool in roadway can complete cleaning tire, reduces the amount of mud of tire, effectively reduces the amount of mud of roadway surface, through the automatic full section centralized dust removal area of adding, effectively purifies the air quality of incoming flow, and synchronously completes the body cleaning.

The invention relates to the technical field of sewage treatment, in particular to a crystal bead fluidization reaction sewage treatment process which comprises the following steps: 1) sewage enters a crystal bead fluidization tower and is in contact with a precipitant under gas stripping to generate small-particle precipitates; 2) combining the small-particle precipitate with the seed crystal to form a prototype of crystal beads, and continuously fluidizing and circulating in a crystal bead fluidizing area to form mature crystal beads; (3) precipitating and gathering mature crystal beads at the bottom of the crystal bead fluidization tower, and discharging from a crystal bead collecting opening; sewage passes through the clarification area and is discharged from the water outlet; the method comprises the following steps: a) mixing water discharged from a crystal bead fluidization tower with a coagulant to form a small floc mixture; b) feeding the small floc mixture into the efficient separation tower, contacting with a flocculating agent, and circularly fluidizing under the action of gas stripping until the large floc is large and settles to the bottom of the efficient separation tower, and c) discharging the large floc from a sludge discharge port at the bottom of the efficient separation tower, mixing the large floc with the sewage, and feeding the mixed floc into the crystal bead fluidization tower. The sludge discharge amount is small, and the sewage treatment equipment occupies a small area.

The utility model discloses a gas field produced water treatment device, and relates to the technical field of water treatment equipment. The gas field produced water treatment device comprises a jet device, an aeration oxidation pond, a booster pump, a silicon carbide filtering assembly, a backwashing water tank, a cleaning water pump, a cleaning water tank, a scale inhibitor dosing tank, a scale inhibitor dosing pump, a pipeline mixer and a compressed air storage tank, wherein the jet device is arranged at the liquid inlet end of the aeration oxidation pond, the liquid outlet end of the aeration oxidation pond is communicated and connected with the silicon carbide filtering assembly through the booster pump, and the output end of the silicon carbide filtering assembly is communicated and connected with the input end of the backwashing water tank, the input end of the cleaning water tank and the input end of the pipeline mixer. The utility model has the advantages of no need of flocculation dosing, high filtering efficiency, less self-water consumption, stable and excellent effluent, small occupied area, low operation cost, less sludge amount and high automation degree.
