Adjacent connection type double-body reaction kettle equipment based on planting method fluorine-removing water treatment, and use method of adjacent connection type double-body reaction kettle equipment

Abstract

The invention relates to adjacent connection type double-body reaction kettle equipment based on planting method fluorine-removing water treatment. The equipment comprises a cylindrical cylinder provided with an upper cover and a lower cover plate, wherein the bottom of the cylindrical cylinder is fixedly connected with a pedestal bracket. The equipment is characterized by further comprising a planting / plant-removing double-purpose bed arranged in the cylindrical cylinder; the planting / plant-removing double-purpose bed comprises a semi-circular screen planting / plant-removing sheet group A and a semi-circular screen planting / plant-removing sheet group B which contain planting type hydroxyapatite filter grains and are arranged in adjacent connection type left and right semi-cylindrical sealing cylinders correspondingly; a pure water outlet valve is arranged on the upper part of the left semi-cylindrical sealing cylinder and a raw water inlet valve is arranged on the lower part of the left semi-cylindrical sealing cylinder; a washing water outlet valve is arranged on the upper part of the right semi-cylindrical sealing cylinder and a washing water inlet valve is arranged on the lower part of the right semi-cylindrical sealing cylinder. The adjacent connection type double-body reaction kettle equipment based on planting method fluorine-removing water treatment has high fluorine removing efficiency, is simple, convenient and reliable in operation for a novel planting method fluorine-removing water treatment process, and can meet the requirement of the novel planting method fluorine-removing water treatment process.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to a contiguous two-body reactor equipment based on a planting method for defluoridation water treatment and a method for using the same. Background technique [0002] Fluorine is one of the essential trace elements for the human body, but long-term drinking of high-fluorine water can lead to fluorosis, which will seriously affect human health. Therefore, the World Health Organization has announced a regulation that the fluorine content of drinking water should not exceed 1.5mg / L. Nowadays, the research on fluoride removal water treatment methods has been highly valued by various countries. The methods of fluoride removal water treatment published in the previous research mainly include coagulation sedimentation method, chemical precipitation method, electrodialysis method, electrocoagulation method, reverse osmosis method, nanofiltration method, ion Ex...

Problems solved by technology

However, this method still has the following obvious deficiencies: first, the aluminum ion content in aluminum-based water treatment materials is within the standard range, but still higher than non-aluminum-based water treatment materials, and there is a risk of excessive aluminum ions; The process and equipment for processing materials are relatively complicated, and they have to go through processes such as filtration, coagulation, and precipitation. The problem of reduced effectiveness
