Embodiment 1

[0020] (1) The average water quality of the primary and secondary concentrated water of #3 and #4 reverse osmosis systems in a plant is shown in Table 1. The content of PTP-0100 antiscalant in system operation is 16mg / L.

[0021] Table 1 Test water quality

[0022]

[0023] (2) Start the feed water pump and adjust the water inlet flow to the preset value. Measure the turbidity of the effluent water every 30s. When the turbidity of the fluidized bed effluent is stable, turn on the dosing pump to add softener, quickly adjust the dosing flow rate to the preset value, and the softening-induced clarification process begins.

[0024] (3) Test water quality according to Table 1, choose NaOH as softener. The amount of softener is represented by the specific consumption of softener (N), and N is defined as the alkalinity of NaOH and test water (JD m ) ratio of moles. In order to guarantee HCO3 - It is completely neutralized with NaOH, and the theoretical value of N is 1.0.

Abstract

The invention relates to a system for carrying out softening treatment on reverse osmosis concentrated water by means of induced crystallization. The system comprises a reverse osmosis concentrated water collection pool, a softener storage box and an induced crystallization reactor, wherein the reverse osmosis concentrated water collection pool is communicated with an inlet formed in the bottom of the induced crystallization reactor by a water feed pump and an inflow water flow regulating valve; the softener storage box is communicated with the inlet formed in the bottom of the induced crystallization reactor by a softener dosing pump and a softener flow regulating valve; an outlet formed in the top of the induced crystallization reactor is connected with a softened water outlet by a water outlet pipe, and the water outlet pipe is communicated with an inlet of the water feed pipe by a water return pipe; a backflow regulating valve is arranged on the water return pipe; a sampling hole is formed in the middle of the induced crystallization reactor. After the system is adopted, the recycling of the reverse osmosis concentrated water is realized, namely, most of the reverse osmosis concentrated water is recycled, and only a small amount of backwashing water of the reactor is discharged outside; furthermore, the component of industrial salt in the reverse osmosis concentrated water is completely recycled, so that the reliable recycling of the reverse osmosis concentrated water is realized.

Description

technical field [0001] The invention belongs to the technical field of industrial waste water reuse, and in particular relates to a reverse osmosis concentrated water induced crystallization softening treatment recovery system of a power plant make-up water treatment system. Background technique [0002] When reverse osmosis technology is used for water treatment, a certain amount of concentrated water will be produced, especially when fresh water is produced from brackish water, the amount of concentrated water is even greater than that of fresh water. If it cannot be recycled and discharged directly, it will not only cause waste of water resources, but also cause environmental impact. At present, the reverse osmosis concentrated water treatment methods mainly include: deep well injection, filter flushing, dust removal for boilers, salt production, electrolysis, membrane distillation, and membrane crystallization. The invention proposes the technology of using induced crys...
