Embodiment Construction

[0042] below, in figure 1 , figure 2 In the wastewater treatment system shown, in order to apply the present invention to have image 3 The case of a pre-coated vacuum filter with a scraper device shown is explained as an example.

[0043]

[0044] exist figure 1An example of a flow diagram of a wastewater treatment system is shown in . This flowchart assumes treatment of waste water such as grinding waste water, acid waste water, and flexographic printing ink waste water.

[0045] A waste water tank 12, a reaction tank 14, and a vacuum filter 16 are provided as a basic structure. In addition, an alkali solution tank 18 and an inorganic coagulant tank 20 are attached to the reaction tank 14 .

[0046] In this embodiment, slaked lime (Ca(OH) 2 ) water dispersion, aluminum sulfate (Al 2 (SO 4 ) 3 ·nH 2 O), PAC (Al 2 (OH) n C 16-n ) and other aqueous dispersions. In addition, these respective tanks 18 and 20 are provided with agitators 22 and 22 , and supply pipe...

Abstract

The invention provides a vacuum filtering apparatus and an operating method thereof. A precoated layer vacuum filtering apparatus may operate in manner of irrelevant to the concentration and the characteristics of waste water and easily setting the feeding speed of the scraping knives of a scraper device. In a precoated layer vacuum filtering apparatus (16) equipped with a filtering groove 936), a filtering drum (38), and a scraper device (46) provided with scraping knives (48), a filter liquor flow measuring device (82) and a control device (86) connected with an indication input unit (88) and a display unit (90) are disposed. The indication input unit (88) sets feeding speed of multiple scraping knives (48) and transmits the feeding speed to a knife feeding driving unit with the control device (86) in order to control the scraping knives with set feeding speed. In addition, a structure is provided and is capable of automatically acquiring flow measurement data from the filter liquor flow measuring device and corresponding to the set feeding speed of the scraping knives of the scraper device and displaying the flow measurement data on a display unit.

Description

technical field [0001] The invention relates to a pre-coated vacuum filter unit and a method of operating the same. Specifically, it relates to a pre-coat vacuum filtration system capable of efficiently performing filtration operation from high-concentration wastewater to low-concentration wastewater, and contributing to reduction in the amount of pre-coat material used and discharge of cake (cake) device and its method of operation. Background technique [0002] The meanings of main terms used in this specification etc. are as follows. [0003] The "required treatment volume" refers to the minimum waste water treatment volume that must be treated by the user within the maximum operating time (for example, 8 hours to 24 hours). [0004] "Filtration stock solution" refers to a substance prepared by adding a coagulant or the like to wastewater. In addition, "wastewater" and "filter stock solution" hardly change in capacity. In addition, the "fine particles" described in th...
