Embodiment

[0038] Example: such as Figure 1-2 As shown, a dosing device based on lime milk multi-point dosing reaction technology is characterized in that it mainly includes a dosing platform 1, a medicine storage tank 2, a dosing pump 3, a multi-point dosing pipe 4, and a cleaning device 5 and controller 6,

[0039] The dosing platform 1 is connected to the center of the sewage treatment tank through connecting rods 11, and a protective net 12 for preventing debris or people from falling into the sewage treatment tank is provided between the connecting rods 11.

[0040] The medicine storage tank 2 is arranged on the dosing platform 1, and the medicine storage tank 2 includes a dosing port 21 arranged on the top of the medicine storage tank 2 for adding milk of lime, and is arranged on the upper part of the side wall of the medicine storage tank 2 for connecting with the cleaning device 5. For cleaning the cleaning port 22 inside the medicine storage tank 2 and the medicine outlet pipe...

experiment example

[0059] Experimental example: the research example provides the impact of the dosing device on the amount of milk of lime

[0060] Experimental equipment: 1 set of dosing device provided in the example, 1 set of common single-point dosing device on the market.

[0061] Experimental conditions: add viscose fiber wastewater with the same parameters in two sewage treatment tanks with the same specifications, set the dosing device provided by the embodiment and a commercially available common single-point dosing device on the sewage treatment tanks, respectively Add milk of lime with the same parameters in the pool for pH adjustment and sulfate removal, adjust the pH value and sulfate of viscose wastewater in the two sewage treatment pools to the same parameters, and calculate the amount of milk of lime that needs to be added. The experimental results are shown in the table 1,

Abstract

The invention provides a dosing device and method based on lime milk multi-point dosing reaction technology, including a dosing platform, a medicine storage tank, a dosing pump, a multi-point dosing pipe, a cleaning device and a controller, and a medicine storage tank Set on the drug dosing platform, the drug storage tank includes a drug feeding port, a cleaning port and a drug outlet pipe, the drug dosing pump is set at the connection between the drug outlet pipe and the drug storage tank, and the multi-point drug feeding pipe includes a rotating tube, which is spiral stepped A plurality of dosing pipes, diffusion devices and driving devices installed on the rotating tube. The diffusion device includes diffusion pipes, diffusion motors and diffusion blades. The cleaning device includes suction pumps, suction pipes and cleaning pipes. The controller is installed on the dosing platform. , the controller is respectively connected with the dosing pump, the multi-point dosing pipe and the cleaning device through the relay. In a word, the invention has a novel structure, can effectively reduce the amount of milk of lime, has advantages in the treatment of viscose fiber wastewater, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a dosing device and method based on lime milk multi-point dosing reaction technology. Background technique [0002] Viscose fiber is the kind of chemical fiber that is closest to the quality of natural fiber, and occupies an important position in the textile industry. At the same time, viscose fiber production will produce a large amount of waste water (short fiber 300m 3 / t, long fiber 1200m 3 / t), mainly includes two categories of acidic and alkaline wastewater, of which acidic wastewater mainly comes from spinning workshops and acid stations, including plasticizing bath overflow water, washing spinning machine water, acid station filter washing water, silk washing Water and post-treatment pickling water, etc.; alkaline wastewater mainly comes from alkali station drainage, raw liquid workshop wastewater glue tank and equipment washing water, filter cloth ...
