Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the waste water produced by regeneration in the existing ion exchanger floating bed water production process has a high pH and cannot be discharged directly, and proposes an industrial soft water production process. The waste water produced by regeneration is close to neutral and meets the direct discharge standard , save the amount of liquid caustic soda

Embodiment Construction

[0011] The water production process of the present invention is as follows: raw water pump --- pretreatment --- raw water tank --- raw water pump --- mechanical filter --- front positive bed --- positive floating bed --- intermediate water tank -- -Middle pump---front shade bed---yin floating bed---mixed bed---demineralized water tank---demineralized pump---water unit.

[0012] On the basis of the existing technology, the present invention sets the pre-equipment and uses the principle of incomplete regeneration of ion exchange resins to change the operation steps to realize the regeneration of the anion and yang bed resins. At the same time, it can also effectively control the acid-base concentration of waste water during regeneration and realize the regeneration of acid-base. The waste water is directly discharged, and the standard discharge can be achieved without affecting the normal regeneration.

[0013] When the water production is in normal operation, the raw water ente...

Abstract

The invention discloses a production process for industrial soft water. The production process comprises the following process flow: a raw water pump; pretreatment; a raw water tank; a raw water pump; a mechanical filter; a preposed cation bed; a cationic floating bed; an intermediate water tank; an intermediate pump; a preposed anion bed; an anionic floating bed; a mixed bed; a desalting water tank; a desalting pump; a water using unit. According to the invention, through additional arrangement of the preposed cation bed and the preposed anion bed, treatment load of the cationic floating bed and the anionic floating bed is mitigated and the operation cycles of the cationic floating bed and the anionic floating bed are effectively prolonged; and waste water produced after regeneration of the floating beds is almost neutral water, production of acid-base waste water in the process of soft water production is reduced, the produced waste water reaches the standard of direct discharge, liquid alkali for neutralization is greatly reduced, and treatment cost for acid-base waste water is reduced for enterprises.

Description

technical field [0001] The invention relates to the technical field of water production, in particular to an industrial soft water production process, which reduces the generation of acid-base wastewater in the soft water production process. Background technique [0002] The water quality requirements of industrial soft water are the water quality requirements of power plant boilers, the process raw water is river water, and the water production process adopts the ion exchanger floating bed process. The main equipment includes positive floating beds, negative floating beds, and mixed beds. In recent years, due to the continuous improvement of environmental protection requirements, the acid and alkali wastewater generated by the recycled water bed must be discharged up to the standard according to the wastewater discharge standards formulated by the environmental protection department (the main discharge index is that the pH value must be greater than 7). For normal water pro...
