Receive water body pressure, make the development that industrial zone is healthy and orderly, the implementation on time of national and local key project is effectively ensured, has
Great environmental benefit and social benefit.
With the popularization of zero-discharge technology, the zero-emission for the waste water realized substantially at present, but abraum salt caused by the evaporation of end,
Belong to danger wastes, therefore technique of zero discharge also needs further to extend, Expansion development abraum salt wsates resources project.Main flow work at present
Skill is that nanofiltration divides salt evaporation and sal prunella coproduction.Because containing a certain amount of COD in coal chemical industrial waste water, COD presence have impact on entirely
The product quality of by-product salt.Which kind of technique mixed salt separation is either carried out using and realizes salt recycling, is all had a problem that：It is high
COD removal problem in salt waste water, COD can not will influence the quality of salt in real time outside removal system.Coal chemical industrial waste water COD spy
Sign is：Complicated component, organic pollution content are high, and COD is up to ten or even hundreds of gram per liters, the mass fraction of salt generally 5% with
On, it is difficult to realize biochemical degradation COD.
Organism kinds are more in coal chemical industrial waste water, complicated component (is mostly indoles, quinolines, carbazoles, pyridines etc. one
A little hardly degraded organic substances), it high salinity and can not be completed using biodegradable mode, cause the problem to become current coalification
One bank of work waste water reclaiming, how by improving current water treatment technology, solve the problems, such as that COD is selection in haline water
Suitable equipment, rational technique remove COD, ensure that by-product salt meets Nacl one-level refined salt standard, therefore seek a kind of application
COD devices are removed in coal chemical industrial waste water and technique is significant.

Tower B, adsorption tower C and adsorption tower D waste water inlet connection, the production jellyfish pipes of the tower adsorption systems of COD tetra- respectively by produce water valve with
Adsorption tower A, adsorption tower B, adsorption tower C and adsorption tower D production water out connection, the backwash water water inlet pipe of the tower adsorption systems of COD tetra-
It is connected respectively by backwash water water intaking valve with adsorption tower A, adsorption tower B, adsorption tower C and adsorption tower D production water out, the towers of COD tetra-
The backwash water water producing pipe of adsorption system passes through backwash aquatic products water valve and adsorption tower A, adsorption tower B, adsorption tower C and adsorption tower D respectively
Water inlet connection.
Reference picture 2, the adsorption tower A, adsorption tower B, adsorption tower C and adsorption tower D waste water inlet outside connect in parallel to enter
Water valve and backwash aquatic products water valve, adsorption tower A, adsorption tower B, the interior connection spray thrower of adsorption tower C and adsorption tower D waste water inlet；Inhale
Attached tower A, adsorption tower B, adsorption tower C and producing for adsorption tower D connect connection production water valve and backwash water water intaking valve in parallel outside water out；
In adsorption tower A, adsorption tower B, adsorption tower C and adsorption tower D macropore charcoal absorption is sequentially provided with by waste water inlet to water out is produced
Layer, mesoporous activated carbon adsorption layer and large micropore activated carbon adsorption layer.
Specific embodiment of the present utility model is that detailed process is as follows：
As shown in figure 1, the waste water from pre-treating technology unit flows through adsorption tower A (this equipped with activated carbon from top to bottom
When Open valve XV01A and XV02A), Open valve XV01B and XV02B (adsorption tower B operations) after adsorption tower A absorption 1-2h, suction
XV01C and XV02C (adsorption tower C operations) is opened after attached tower B absorption 1-2h, now the towers of ABC tri- are in running status.Adsorption tower is transported
During row when adsorption tower aquifer yield reduces, and intake pressure rises, represent that the tower needs to carry out backwash procedure.
Illustrated below by taking adsorption tower A as an example, when adsorption tower A needs to carry out backwash, closing adsorption tower A water intaking valve
XV01A and production water valve XV02A, open adsorption tower A backwash water intaking valve XV01'A and backwash production water valve XV02'A, backwash about 3min
Backwash valve (XV01'A, XV02'A) opening adsorption tower A water intaking valves (XV01A, XV01A) are closed afterwards to continue to adsorb.Because of charging
During be the intermittent time be present between the tower of adsorption tower three, so carrying out backwash with the sequencing of charging, do not influence normal
Operation and adsorption process.
The main pipe of production water is provided with COD detectors, and when reading is showed more than producing water required value on COD detectors, expression is inhaled
Attached water quality can not meet next technological standards, also imply that adsorption tower A fails, and now need to cut out regeneration into being about to A towers,
D towers put into operation, and open valve XV01D, XV02D (put into operation adsorption tower D), close valve XV01A, XV02A (cutting out adsorption tower A), this
When just by original absorption three tower A-B-C be changed to adsorption tower B-C-D, so carry out circulation B-C-D, C-D-A, D-A-B, A-B-C, remain
Remaining single column is as standby.
Filling for the acticarbon of single column, as shown in Fig. 2 absorption single column can be divided into three layers of absorption of upper, middle and lower
Layer, waste water from top to bottom pass through successively, and the superiors are using big mesoporous activated carbon, middle level using mesoporous activated carbon, lower floor using big micro-
Mesoporous activated carbon.Because of the complicated component of COD in coal chemical industrial waste water, process requirements individually can not be met using one or two kind of activated carbon,
COD molecular weight also differs widely, and because of the adsorption mechanism of activated carbon, upper strata must use big mesoporous activated carbon, otherwise mesopore or big
Micropore can block hole, reduce the adsorption rate of activated carbon, so the utility model patent is divided greatly using in absorption waste water successively
Son amount, intermediate molecular weight and small-molecular-weight realize that the COD in waste water is removed, while high degree make use of the Gao Bibiao of activated carbon
The adsorption effect in face and effectively raise adsorption efficiency.
Resin tower series operation and regeneration use PLC or DCS automated system operational controls.
The technique contains two parts for the main subpackage of absorption of coal chemical industrial waste water：1）Three layers of charcoal absorption of single column；2）Four
Tower parallel connection technology, including absorption, backwash process, four towers are in parallel to adsorb the standby parallel connection technology of a tower using three towers, ensures three towers
Order four towers of water inlet recycle, so as to conveniently realize the COD of coal chemical industrial waste water absorption.Simultaneously in adsorption process, solid-liquid
Mass transfer is with adsorbing motive force demand, it is necessary to which timing carries out backwash to adsorption tower, therefore the absorption of the tower of moment two of technique meets technique need
Ask, i.e., now single column carries out backwash.By this patent ensure water inlet order by, finally realize COD molecular weight in water from height
To low adsorption process.Four tower parallel connection technology processes are simple, and governing factor is single, and the construction of equipment is compact and easy to operate, is easy to
Carry out the maintenance at scene and disclosure satisfy that the technical indicator of water outlet.
