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
The present invention relates to water technical field processed, particularly the industrial soft water water preparation process of one, reduce the generation of acidic and alkaline waste water in soft water making processes.
Background technology
The water quality requirement of industrial soft water is station boiler water quality requirement, and the former water of technique is river, and water preparation process adopts ion-exchanger floating bed technique, and major equipment has positive floating bed, cloudy floating bed, mixed bed.In recent years, due to improving constantly of environmental requirement, regenerate acid that water bed processed produces, wastewater discharge standard that alkali waste water must be formulated by environmental administration accomplish qualified discharge (primary discharge index is that pH value must be greater than 7).The aquatic product of normal system, positive floating bed running period is 1/2nd of cloudy floating bed, and the number of times namely regenerating positive floating bed is the twice regenerating cloudy floating bed number of times.The waste water that the regeneration of sun floating bed produces is sour water, and the waste water that cloudy floating bed regeneration produces is alkaline water.In order to accomplish qualified discharge, technique to adopt in neutralization tank acidic and alkaline waste water and rear discharge, but due to sour water generation large compared with alkaline water generation, just therefore still need to use sour water in a certain amount of liquid caustic soda He unnecessary that all acid waste water can be made to obtain qualified discharge.Simultaneously in and process in, analyze continually, waste a large amount of manpowers, manipulation strength is large.
For this reason, need to research and develop a set of economical and practical waste water treatment process, under the prerequisite not affecting water bed processed regeneration, no matter after anion bed or cation bed regeneration, the waste water pH value of generation, close to neutral water, thus can directly discharges.
Summary of the invention
It is high that the object of the invention is to solve the waste water potential of hydrogen regenerating generation in existing ion-exchanger floating bed water preparation process, the problem that can not directly discharge, proposes a kind of industrial soft water water preparation process, and the waste water that regeneration produces is close to neutral, reach direct emission standard, save liquid caustic soda consumption.
The object of the invention is to be achieved by the following technical programs, industrial soft water water preparation process, adopt ion-exchanger floating bed technique, flow process comprises: former water water pump, and------------------------------water unit used by sweet-water tank---except salt pump---to mixed bed to cloudy floating bed to line pump to intermediate water tank to positive floating bed to mechanical filter to raw water pump to raw water box in pre-treatment, it is characterized in that, before described positive floating bed, add preposition cation bed, before described cloudy floating bed, add fore positive bed.
Water flow-path processed of the present invention is as follows: former water water pump, and------------------------------------water unit used by sweet-water tank---except salt pump---to mixed bed to cloudy floating bed to fore positive bed to line pump to intermediate water tank to positive floating bed to preposition cation bed to mechanical filter to raw water pump to raw water box in pre-treatment.
When water processed normally runs, former water enters positive floating bed after preposition cation bed, can remove the suspended substance that former water middle filtrator is not removed on the one hand, on the other hand the former water ions content of pre-treatment, alleviate positive floating bed processing load, effectively extend the cycle of operation of positive floating bed; The former water dealt through positive floating bed enters intermediate water tank, is pressurizeed and delivers to fore positive bed, enter cloudy floating bed and again process, alleviate the load of cloudy floating bed equally, also effectively ensured the running period of cloudy floating bed after pre-treatment cation bed water by line pump.
Regeneration operational scheme: positive floating bed spent regeneration, no matter whether preposition cation bed lost efficacy, and adjustment is stopped transport, and together regenerated with the positive floating bed of inefficacy.Sun floating bed enters regenerated liquid, and after adjustment bed internal pressure, the regeneration liquid pump of positive floating bed being discharged by in-line pump is to preposition cation bed.Preposition cation bed and positive floating bed realize series-connected regenerative, and adjust regenerated liquid regeneration proportion, temporally require to control well the positive floating bed recovery time, preposition cation bed regeneration effect need not be considered, after positive floating bed reaches the recovery time, and stops regeneration.Regenerated liquid acidity is after positive floating bed and preposition positive floating bed resin absorption exchange, and in waste water, acidity content is almost nil, reaches acid waste water treatment effect.
Cloudy floating bed spent regeneration, regenerated liquid is by entering fore positive bed after cloudy floating bed, and regenerated liquid basicity is after resin absorption exchanges, and in waste discharge, pH value is 7, reaches alkaline waste water treatment effect.
Beneficial effect: the present invention is by adding preposition cation bed and fore positive bed, alleviate the processing load of positive floating bed, cloudy floating celebrating, the cycle of operation of the positive floating bed of effective prolongation, cloudy floating bed, the waste water produced after floating bed regeneration is close to neutral water, reduce the generation of acidic and alkaline waste water in soft water making processes, reach direct emission standard, significantly reduce neutralization liquid caustic soda, for enterprise reduces acidic and alkaline waste water treatment operating costs.
