Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments.

[0034] A mobile box-type river and lake water defluoridation device is characterized in that: it includes a hollow shell inside, and the two sides of the shell are respectively provided with a mixing part and a post-processing part, and the mixing part and the post-processing part There is a filter part between;

[0035] The mixing section and the filtering section are separated by a fan-shaped triangular weir baffle plate 7 arranged vertically, a suction pump 2 is arranged at the bottom of the mixing section, and a flocculation pump 2 is arranged above the suction pump 2. Settling box 6, the said pump 2 and the flocculation settling box 6 are separated by an inclined steel plate 6-1, and a composite flocculant dosing box 5 is arranged above the inside of said flocculation settling box 6, said The bottom of the composite flocculant d...

Abstract

The invention relates to a mobile box type river and lake water defluorination device which comprises an internally hollow outer shell, wherein a mixing part and an after-treatment part are respectively arranged on two sides in the outer shell; a filtration part is arranged between the mixing part and the after-treatment part; adsorption filtration is realized by an activated alumina adsorption filtering plate in the filtration part after performing chemical coagulation in the mixing part, wherein the activated alumina adsorption filtering plate can be reused by regeneration treatment after adsorption to reach saturation. For surface water containing excessive fluorine, the mobile box type river and lake water defluorination device performs first-stage treatment by chemical coagulation ofa composite defluorination coagulant and performs second-stage treatment by adsorption filtering of activated alumina, and has characteristics of non-stop operation, no need to stop the operation forregeneration, high defluorination selectivity, relatively easy regeneration, good defluorination effect, convenient use and mobility.

Description

technical field [0001] The invention relates to the technical field of water body impurity removal, in particular to a mobile box-type river and lake water defluorination device. Background technique [0002] Fluorine is one of the essential trace elements for human life. Appropriate amount of fluorine can strengthen bones and teeth and reduce the incidence of dental caries. However, when fluorine accumulates in the human body for a long time, it can penetrate deep into the bone and generate CaF2, resulting in brittle bones, tooth stains, ligament calcification, joint stiffness and even paralysis, and severe cases lose the ability to work. Chronic fluoride poisoning can also cause soft tissue damage, and even tumors, and there is a risk of causing leukemia. According to reports in recent years, long-term intake of excessive fluoride can also cause cancer and mutagenesis. [0003] The fluorine content of drinking water sources in many areas of my country is relatively high...
