Abstract
The invention discloses a kind of raw water processing method, the method is as follows: (1) first filtering: detaching raw water by strainer, be put into collecting-tank；(2) waddingization: launching flocculant into collecting-tank, and sediment will be discharged；(3) raw water after waddingization secondary filter: is subjected to secondary filter into filter；(4) it adsorbs: the raw water after secondary filter is subjected to adsorption treatment by resin adsorption tower；(5) it is acidified: the raw water after adsorption treatment is acidified, liquid chlorine, sodium hypochlorite are added into water；(6) desalination: first adding reducing agent sodium hydrogensulfite into water, carries out desalting processing using electrodeionization；(7) deoxygenation: vacuum dust cather deoxygenation is utilized, and adds oxygen scavenger into water.Operation of the present invention step is succinct, after wastewater treatment, can reduce the maintenance cost of heating system with effective solution impurities in water problem.
Description
Technical field
The invention belongs to water treatment fields, and in particular to a kind of raw water processing method.
Background technique
With the continuous development of catering industry, influence of the discharge of sewage from catering business to ambient enviroment is increasingly severe, each
Relevant rules and regulations are worked out all to determine the qualified discharge of sewage from catering business, and constantly mentioning with levels of substance in place
Height, a middle chemical article are more also popularized, and get worse the pollution level of the sanitary sewage of people also, and then lead to river water
Pollution also come it is also serious, existing heat supply or waters supply of power plant be all after used absorption river water processing carry out using, but now
Some process method steps are more, and operation is comparatively laborious, and treatment effect is sometimes unsatisfactory.
Summary of the invention
Goal of the invention: the purpose of the present invention is to solve deficiencies in the prior art, provide a kind of raw water processing method,
It solves the above problems.
Technical solution: a kind of raw water processing method of the present invention, the method are as follows:
(1) first filtering: raw water is detached by strainer, is put into collecting-tank；
(2) waddingization: launching flocculant into collecting-tank, and sediment will be discharged；
(3) raw water after waddingization secondary filter: is subjected to secondary filter into filter；
(4) it adsorbs: the raw water after secondary filter is subjected to adsorption treatment by resin adsorption tower；
(5) it is acidified: the raw water after adsorption treatment is acidified, liquid chlorine, sodium hypochlorite are added into water；
(6) desalination: first adding reducing agent sodium hydrogensulfite into water, carries out desalting processing using electrodeionization；
(7) deoxygenation: vacuum dust cather deoxygenation is utilized, and adds oxygen scavenger into water.
Preferably, filter upper layer filtrate is anthracite or active carbon, and intermediate filtrate is quartz sand, and lower layer's filtrate is
Magnetic iron ore or ceramic grain.The utility model has the advantages that operation of the present invention step is succinct, it, can be with effective solution impurities in water after wastewater treatment
Problem reduces the maintenance cost of heating system.
Specific embodiment
A kind of raw water processing method, the method are as follows:
(2) first filtering: raw water is detached by strainer, is put into collecting-tank；
(2) waddingization: launching flocculant into collecting-tank, and sediment will be discharged；
(3) raw water after waddingization secondary filter: is subjected to secondary filter into filter；
(4) it adsorbs: the raw water after secondary filter is subjected to adsorption treatment by resin adsorption tower；
(5) it is acidified: the raw water after adsorption treatment is acidified, liquid chlorine, sodium hypochlorite are added into water；
(6) desalination: first adding reducing agent sodium hydrogensulfite into water, carries out desalting processing using electrodeionization；
(7) deoxygenation: vacuum dust cather deoxygenation is utilized, and adds oxygen scavenger into water.
In this example, filter upper layer filtrate is anthracite or active carbon, and intermediate filtrate is quartz sand, lower layer's filtrate
For magnetic iron ore or ceramic grain.
Operation of the present invention step is succinct, after wastewater treatment, can reduce heating system with effective solution impurities in water problem
Maintenance cost.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, according to the technical essence of the invention
Any simple modification, equivalent change and modification to the above embodiments, all of which are still within the scope of the technical scheme of the invention.
