Problems solved by technology

[0003] The use of coagulation technology in small water treatment equipment needs to solve two main technical problems: one is the miniaturization of the dosing device, and the other is the miniaturization of the stirring power
Studies have shown that the effect of this flocculation is 1.67 times higher than that of the first flocculation, but it does not help the equipment of the treatment process and the miniaturization of the equipment

Embodiment Construction

[0022] As shown in Figure 2, it is a schematic diagram of the principle of a domestic iron removal device produced by the patented technology of the present invention. In the figure, the circulation pump 1 extracts the treated water from the lower part of the container 4 for forced circulation. After the treated water passes through a dosing device 2 that can add medicine and gas at the same time, it enters the mixing pipe 3 and relies on hydraulic power for high-speed rotation and mixing. After the mixed water enters the container 4 again, since the hydraulic power has been consumed in a large amount in the mixing tube 3, when entering the container 4, the power is greatly reduced, and the volume of the container 4 is much larger than the mixing tube 3, therefore, The treated water can only rotate at a very low speed in the container 4 . Through structural design, the rotation of the treated water in the mixing tube can reach the time and intensity (lower limit) required for ...

Abstract

The invention provides a method for circulation and coagulation water treatment technology, which comprises two basic processes of feeding and mixing. Water being treated is subjected to more than one circulation of feeding-mixing, then enters the processes of flocculation and precipitation (called 'circulation micro flocculation'), or is subjected to more than one circulation of feeding-mixing-initial flocculation and then enters the processes of final flocculation and precipitation (called 'circulation initial micro flocculation'). The method is beneficial to reducing the power demand of hydraulic stirring, increasing the mixing effect of a flocculating agent and the water being treated, opening up more effective paths for the application of a coagulation method in deferrization, demanganization and defluorination, and also provides possibility for traditional coagulation water treatment technology to be miniaturized and be used on equipment.

Description

technical field [0001] The patent of the present invention is a water treatment process and belongs to the field of water treatment. It includes two basic procedures of dosing and mixing. Its characteristics are: the treated water has undergone more than one dosing-mixing cycle process, so that the water is subjected to cyclic flocculation treatment. According to the different processes completed by a single cycle, it can be divided into cycle micro-coagulation and cycle primary coagulation. Background technique [0002] Coagulation, also known as flocculation, is an important process in water treatment, generally including three process engineering of dosing - mixing - flocculation. Among them, the mixing is carried out immediately after adding the medicine, and the added medicine and the water to be treated are fully mixed with high-intensity stirring. Generally, the speed gradient G of the mixing is required to be about 500-1000 / second, and the mixing time is 10-30 seco...
