Abstract

The invention relates to a multi-stage dosing, crystallizing, granulating and softening device and method for high-hardness water. The multi-stage dosing, crystallizing, granulating and softening device comprises a crystallizing, granulating and softening bed device main body, and the crystallizing, granulating and softening bed device main body is provided with a seed crystal discharging port, a water inlet, a multi-stage dosing port, a seed crystal feeding port and a water outlet from bottom to top; and the crystallization granulation softening bed device main body is also provided with three observation windows and three sampling ports from bottom to top. The multistage dosing, crystallizing, granulating and softening device has the advantages of being good in water drinking effect, small in occupied area, low in operation and maintenance cost, easy to operate and the like.

Description

technical field [0001] The invention relates to a water treatment device and method, in particular to a multi-stage chemical dosing, crystallization, granulation and softening device and method for high hard water. Background technique [0002] The hardness index in the water body is the main control index in the industrial water index. The hardness factor in the water body is the main hazard factor in the industrial water. It is the main obstacle to the safety of industrial water system equipment, energy saving and emission reduction. Key points and difficulties of zero emission governance. In the process of industrial water use, due to evaporation and concentration, water processes such as washing and sewage discharge will produce a large amount of high-hardness sewage that is difficult to reuse. It must be effectively reduced and removed before it can be reused to reduce or avoid sewage pollution. For the treatment of hard water, many effective softening methods have bee...
