Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of wastewater treatment, and particularly relates to a special powder medicament dosing device for fluorescent wastewater. BACKGROUND
[0002] The fluorescent agent wastewater treatment equipment mainly adopts the following technologies: physical adsorption method, chemical oxidation method, biological degradation method, etc. Among them, the physical adsorption method uses adsorbents with high specific area, such as activated carbon, zeolite, etc., to remove the fluorescent substances in wastewater by adsorption, which has low investment cost and good removal effect.
[0003] At present, there are special powder medicaments for fluorescent wastewater on the market, which are mainly composed of powdered activated carbon and other powder medicaments, and have good treatment effect on fluorescent wastewater. However, the powder medicament also has some problems in the use process. On the one hand, the powder medicament adding process often causes dust, which not only wastes the medicament, but also causes secondary pollution to the surrounding environment; on the other hand, the powder medicament has poor fluidity, and often needs manual intervention during the adding process, which has low automation level. SUMMARY
[0004] The purpose of the present application is to provide a special powder medicament dosing device for fluorescent wastewater, to solve the problems of easy dusting and low operation automation level in the powder medicament adding process in the prior art.
[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present application is as follows: a special powder medicament dosing device for fluorescent wastewater, comprising a medicament storage tank, a powder conveying pump and a reaction integrated pool.
[0006] The medicament storage tank is modified from a conventional 1000L volume tray type PP square ton barrel. The powder medicament is filled and packed in the medicament storage tank at the factory of the medicament supplier, and then transported to the use site, so as to avoid dusting caused by configuration and packing of the medicament at the use site.
[0007] Four pulleys are fixed under the ton barrel tray to facilitate the transfer of the ton barrel. Two pulleys on one narrow side are universal wheels for adjusting the forward direction, which facilitates the transfer of the medicament storage tank in the limited space at the site.
[0008] A discharge port is installed on one side of the bottom of the medicament storage tank, a manual valve is installed outside the discharge port to prevent the medicament from spilling during the transfer of the medicament storage tank, and a running knot is installed at the rear end of the manual valve to facilitate the disassembly and assembly of the medicament storage tank during replacement.
[0009] The barrel wall opposite to the discharge port of the medicament storage tank is inclined, the included angle between the barrel wall and the ground is greater than 50°, a variable frequency vibration pump is fixed outside the barrel wall by bolts, so as to ensure that the powder medicament in the barrel can flow to the discharge port.
[0010] The powder conveying pump is a pneumatic diaphragm powder conveying pump. Compared with conventional screw pumps, diaphragm pumps have better sealing performance and more guaranteed powder flow stability when conveying powdered drugs.
[0011] In this design, the integrated reaction tank is a fully enclosed structure to prevent powder from escaping from the inlet and causing dust.
[0012] The integrated reaction tank consists of chamber 1, chamber 2, chamber 3, and a reaction zone. The powdered reagent enters the interior of the reaction tank through chamber 1, with the inlet submerged underwater. The powdered reagent in chambers 1, 2, 3, and the reaction zone is thoroughly mixed with the wastewater to reduce the amount of powder released into the air.
[0013] The length of the partition between chambers 1, 2, and 3 is gradually shortened, thereby reducing the water flow resistance and guiding the powdered medicine to move in the direction of flow from chamber 1 to chamber 2 to chamber 3 and the reaction zone.
[0014] The tops of compartments 1, 2, and 3 are equipped with atomizing spray heads, which combine with the water mist to cause a small amount of powdered medicine that escapes into the air to fall back into the pool.
[0015] After the powdered reagent enters the reaction zone and is fully mixed with the wastewater and adsorbs the characteristic pollutants of the wastewater, polyaluminum chloride and polyacrylamide are added to the water to cause the powdered reagent to precipitate and finally separate from the treated water in the form of sludge.

[0020] The pharmaceutical storage tank is a modified version of a standard 1000L pallet-type PP square ton container (1-1). Powdered pharmaceuticals are mixed and filled into the storage tank at the pharmaceutical supplier's factory before being transported to the use site, avoiding dust generation caused by on-site preparation and filling of pharmaceuticals.
[0021] Four pulleys (1-3) are fixed under the ton barrel tray to facilitate the transfer of the ton barrel. Two pulleys on one narrow side are universal wheels to adjust the forward direction, facilitating the transfer of the medicament tank in the limited space on site.
[0022] A discharge port is installed on one side of the bottom of the medicament tank, and a manual valve (1-4) is installed outside the discharge port to prevent the medicament from spilling during the transfer of the medicament tank.

[0028] The bottom cover plate of the reaction zone is made of PP plate, and the cover plate and the top of the pool body are fixed with glass glue to ensure sealing and facilitate disassembly and internal maintenance in the later stage.
[0029] The liquid level in the reaction pool is 200mm higher than the pool, and the medicament inlet (3-4) pipeline is buried 100mm below the pool. The lengths of the partitions between compartment 1, compartment 2, and compartment 3 in the pool are gradually shortened, gradually reducing the water flow resistance, and guiding the powder medicament to move in the direction of compartment 1, compartment 2, compartment 3, and the reaction zone.
