The invention discloses water treatment equipment. The water treatment equipment comprises a control system, a raw water box, four parallel-connected raw water pumps, three parallel-connected heat exchangers, a flocculating agent feeder, three parallel-connected pan filters, three parallel-connected ultra-filtration devices, an ultra-filtration water box, four parallel-connected RO (Reverse Osmosis) booster pumps, a reducing agent feeder, a scale inhibitor feeder, three parallel-connected safety filters, four parallel-connected primary high-pressure pumps, three groups of parallel-connected primary reverse osmosis devices, a primary RO water box, a sodium hydroxide feeder, four parallel-connected secondary high-pressure pumps, three groups of parallel-connected secondary reverse osmosis devices; a secondary RO water box, two parallel-connected EDI (Electronic Data Interchange) water supply pumps, a sterilizer, a precision filter, an EDI device, a nitrogen-sealed water box, two parallel-connected pure water pumps, a TOC (Total Organic Carbon) remover, a polishing mixed bed and a terminal filter, which are connected in series in sequence. The water treatment equipment has the advantages that the heat exchangers in the water treatment equipment are used when a temperature is lower, and the use of the heat exchangers is stopped when the temperature of the weather rises. The running efficiency of the water treatment equipment is improved.
Description
Technical field
The present invention relates to water-treatment technology field, especially a kind of water treatment facilities.
Background technology
When the high-purity water system of bi-membrane method is used for water temperature Four seasons change than larger area, the aquifer yield of reverse osmosis equipment is subject to
Temperature impact ratio is larger, and the salt rejection rate of counter-infiltration system and aquifer yield are very sensitive to the change of inflow temperature, increase water temperature meeting
Lead to salt rejection rate reduce, this be primarily due to molecules of salt pass through film diffusion rate can accelerate because of the raising of temperature caused by.With
When with coolant-temperature gage increase, water flux is almost linear increase, and this is mainly due under the viscosity through the hydrone of film
Fall, leads to diffusivity to increase；Conversely, at low temperatures, the water flux of film will significantly decline, and salt rejection rate can rise
High.Based on the above characteristic of film, the inflow temperature of reverse osmosiss must select a proper scope, just can put forward high yield water
Amount, stablizes salt rejection rate, reduces operating cost.

38.6m3/h, lift are 38m, and raw water pump 102 provides necessary power for follow-up water treatment facilities；Its running status is by controlling system
System 128 control.
As shown in Fig. 2 heat exchanger 103, because water temperature Four seasons change ratio is larger, the aquifer yield of reverse osmosis equipment is subject to temperature shadow
Ring that ratio is larger, 60% when aquifer yield is 25 DEG C when 10 DEG C is even lower, the salt rejection rate of reverse osmosiss simultaneously and aquifer yield
Change to inflow temperature is very sensitive, increases water temperature and salt rejection rate can be led to reduce, this is primarily due to molecules of salt and passes through film
Caused by diffusion rate can be accelerated because of the raising of temperature.Simultaneously with the increase of coolant-temperature gage, water flux is almost linear increase,
This declines mainly due to the viscosity of the hydrone through film, leads to diffusivity to increase；Conversely, at low temperatures, film
Water flux will significantly decline, and salt rejection rate can raise.Based on the above characteristic of film, the inflow temperature of reverse osmosiss passes through to change
Hot device 103 selects a proper temperature, could improve aquifer yield, stablizes salt rejection rate, reduces operating cost.Water process sets
