Abstract
The invention discloses a kind of industrial sewage process methods, including into sewage be added in heavy metal precipitator, stir 30min after stand 60min, after grain slag is separated, then the liquid after separation is filtered；Wherein, the heavy metal precipitator includes the parts by weight of following component：30~40 parts of ferric trichloride, 25~32 parts of milk of lime, 8~12 parts of polyacrylamide, 8~12 parts of sodium hydroxide, 15~21 parts of sepiolite, 5~7 parts of sodium chloride.The present invention, can be by the heavy metal in sewage, ammonia nitrogen substance by the way that heavy metal precipitator is added in sewage；Wherein ferric trichloride, milk of lime, polyacrylamide and sodium hydroxide can be by the heavy metals (the significant heavy element of the bio-toxicities such as mercury (mercury), cadmium, lead, chromium and metalloid arsenic) in sewage, sepiolite and sodium chloride can effectively purify ammonia nitrogen waste water, have high economic benefit.
Description
Technical field
The present invention relates to a kind of industrial sewage process methods, belong to technical field of sewage.
Background technique
Sewage water treatment method includes physical treatment process, method of chemical treatment and biological treatment.Wherein method of chemical treatment is logical
Chemical reaction and effect of mass transmitting are crossed to separate, remove in waste water in dissolving, the pollutant of colloidal state or be translated into harmless
The waste water treatment process of substance.In method of chemical treatment, it is to add the processing unit based on medicament generates chemical reaction：It is mixed
Solidifying, neutralization, redox etc..
Coagulation-settlement process is good with effluent quality compared with other physico-chemical process, process runs well is reliable, warp
It helps the advantages that practical, easy to operate.Its coagulating sedimentation principle is in sedimentation basin by adding some medicaments into water (commonly referred to as
For coagulant and flocculation aid), so that the particle for being difficult to precipitate in water is aggregated with one another and is formed colloid, then with the impurity in water body
In conjunction with the bigger floccule body of formation.Floccule body have powerful adsorption capacity, suspended matter can not only be adsorbed, moreover it is possible to absorbed portion bacterium and
Dissolved matter.Floccule body is increased and is sunk by absorption, volume.
Summary of the invention
The purpose of the present invention is to provide one kind can be by the processing side of the removal of heavy metal, ammonia nitrogen class in trade effluent
Method.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of industrial sewage process method, including into sewage be added in heavy metal precipitator, stir 30min after stand
60min after separating grain slag, then is filtered the liquid after separation；Wherein, the heavy metal precipitator includes following component
Parts by weight：30~40 parts of ferric trichloride, 25~32 parts of milk of lime, 8~12 parts of polyacrylamide, 8~12 parts of sodium hydroxide, Hai Pao
15~21 parts of stone, 5~7 parts of sodium chloride.
Further, the heavy metal precipitator includes the parts by weight of following component：35 parts of ferric trichloride, milk of lime 28
Part, 10 parts of polyacrylamide, 10 parts of sodium hydroxide, 18 parts of sepiolite, 6 parts of sodium chloride.
Further, the mass ratio of the sewage and heavy metal precipitator is 1:2~3.
Further, the filtering refers to that the liquid after separation successively passes through sandstone, coarse sand, fine sand, active carbon and biology
Film filtering.
Of the invention has the advantages that：
It (1), can be by the heavy metal in sewage, ammonia nitrogen substance by the way that heavy metal precipitator is added in sewage；Wherein trichlorine
Changing iron, milk of lime, polyacrylamide and sodium hydroxide can be by heavy metal (mercury (mercury), cadmium, lead, chromium and the metalloid in sewage
The significant heavy element of the bio-toxicities such as arsenic), sepiolite and sodium chloride can effectively purify ammonia nitrogen waste water, economic effect with higher
Benefit；
It (2), can various impurity effectively in filter sewage by multiple filtration.
