Description

A kind of high salt water treatment facilities

Technical field

This utility model is related to a kind of high salt water treatment facilities.

Background technology

Current high salt water process is usually mechanical accelerating purifying pool, ultrafiltration, cation bed, efficient reverse osmosiss.Reverse osmosis produced water I.e. (middle water) partly fills into recirculated water, partly fills into desalted water through two-pass reverse osmosis deep desalting, sends into main process unit.Concentrated water (60t/h) squeeze into evaporation tank and carry out natural evaporation.Because the concentrated water water yield is big, time-consuming, required place for simple dependence natural evaporation Have high demands.And the reverse osmosis concentrated water discharge water yield is big, and the problems such as reverse osmosiss pollution fouling.

Utility model content

The defect existing for above-mentioned background technology, this utility model provides a kind of high salt water treatment facilities.

For achieving the above object, the technical solution adopted in the utility model is：It includes homogenizing pond, the softening being sequentially communicated Depositing reservoir, more medium filter, hardness removal unit, decarbonizing tower, decarburization pond, efficient reverse osmosis membrane group and product pond, described Soften depositing reservoir to be also connected with mud scratch pool, mud scratch pool is connected with dewaterer, and dewaterer is connected with homogenizing pond, efficiently instead Permeable membrane group is also connected with efficiently reverse osmosis concentrated pond.

This utility model has the advantages that：

1st, anti-Organic Pollution is strong：System can very high COD and BOD concentration even have under the environment of oil run and not Go wrong；In high pH environment, fatty acid carries out saponification, and Organic substance is dissolved in water, and without being adhered on film.Generally cleaning RO film Organic Pollution be to be carried out using the solution of high PH.Efficiently the operation of reverse osmosiss is equivalent to and is carrying out weak solution always Cleaning, so need not often clean, saves operating cost.

2nd, stable against biological contamination is strong：Under conditions of high PH, most of biologies " have dissolved " or have been destroyed, and do not go to pot Biology also cannot be carried out breed.Biology is gone to pot due to huge concentration change between water inlet and concentrated water, consequent Osmotic pressure change makes the cell wall rupture of microorganism.

3rd, no the polluting and have high clearance of silicon：Under high pH condition, the dissolubility of silicon rises rapidly, the dissolving of silicon Degree>2000mg/l, so do not have pollution.Colloid and the activated silica of system feedwater high concentration can be stood.

4th, the pollution of no difficulty soluble salt：Efficiently reverse osmosis technology is to remove hardness to extremely low level first, so can be High pH condition is run, and resin not only removes all of hardness, goes back the polyvalent cation in exchanged water, such as caesium, barium, aluminum, ferrum The presence of these ions can cause the fouling of film.Efficiently the second step of reverse osmosis technology is to remove basicity by way of degassing, Even if no hardness, alkali and do not have polyvalent cation to mean not having the pollution of film under high pH condition, do not have dirty stifled, Fouling is not had to mean that the flux of film can be very high, the response rate is only affected by osmotic pressure.

Brief description

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, before not paying creative labor Put, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is structured flowchart of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work Embodiment, broadly falls into the scope of protection of the invention.

As shown in figure 1, this utility model include being sequentially communicated homogenizing pond, soften depositing reservoir, more medium filter, hardness Removal unit, decarbonizing tower, decarburization pond, efficient reverse osmosis membrane group and produce pond, described softening depositing reservoir also with mud scratch pool Connect, mud scratch pool is connected with dewaterer, dewaterer is connected with homogenizing pond, efficient reverse osmosis membrane group also with efficiently reverse osmosis concentrated Pond connects.Homogenizing pond is connected with haline water water inlet pipe, and haline water passes through preliminary treatment after entering homogenizing pond, enters and softens clarification Pond, goes the most of hardness in eliminating water softening feeding lime breast, iron salt, PAM, liquid caustic soda, magnesium oxide and sodium carbonate in depositing reservoir With materials such as silicon, after clarification and effluent acid adding, the float in more medium filter removal water, granule and colloid, reduce water inlet Turbidity and SDI value, afterwards enter hardness removal unit.Soften after the mud discharged in depositing reservoir enters mud scratch pool and enter Dewaterer is processed, and the sewage after dewaterer separation reenters homogenizing pond and processed, and then outward transport is processed mud.Hardness is gone Except unit removes the calcium ions and magnesium ions of residual in eliminating water.Ion exchange resin in the calcium of hardness, magnesium ion and demineralizer in water is carried out Exchange, make water outlet be difficult to form carbonate scale and sulfate scale.Cation bed water outlet enters carbon dioxide cleaner, is removed with the mode of air blast degassing Free carbon dioxide in water.After decarbonizer degassing, in water, the carbon dioxide of residual is less than 5mg/l, and decarbonizer water outlet is entered Enter decarburization pond.The water outlet of decarburization pond through plus alkali adjust pH after, enter efficient reverse osmosis membrane group, effectively go in eliminating water various from Son, inorganic matters, colloidal particles, antibacterial and organic substance etc..Reverse osmosis produced water enters reuse pool after acid for adjusting pH, through HERO Produce water pump and be transmitted back to for producing, concentrated water sends into pond of temporarily meeting an urgent need after then entering efficiently reverse osmosis concentrated pond.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model Protection domain within.
