Abstract
The present invention relates to a kind of sanitary sewage dephosphorization agent, including dephosphorization agent A to be made up of following component by weight with dephosphorization agent B, the dephosphorization agent A：6.25 parts of aluminium polychloride, 5.42 parts of attapulgite, 2.15 parts of aluminum sulfate, 2.36 parts of ferrous sulfate；The dephosphorization agent B is made up of following raw material by weight：1.85 parts of aluminium polychloride, 6.4 parts of polyvinyl alcohol, 2.15 parts of ferrous sulfate.The dephosphorization agent dephosphorization agent A and dephosphorization agent B of sanitary sewage provided by the invention, although in raw material it is common water treatment agent, but, after compounding, under pH condition in this application, the effect of its dephosphorization greatly promotes, and high phosphorus sanitary sewage phosphorus content after the processing of the application method can be reduced to 0.25mg/L, at or below national standard.
Description
Technical field
The invention belongs to water treatment field, and in particular to a kind of sanitary sewage dephosphorization agent.
Background technology
Sanitary sewage is mainly various detergent and sewage, rubbish, excrement used in urban life etc., mostly nontoxic
Inorganic salts, more containing nitrogen phosphate and sulfur in sanitary sewage, malignant bacteria is more.Especially middle detergent widely uses in recent years, causes
Phosphorus in Domestic Wastewater with Pulverized content remains high, and Phosphorus From Wastewater content height can cause serious pollution, therefore, needs to carry out before discharging
Processing, the phosphorus content in waste water is reduced, now more directly to be handled using aluminium salt, still, aluminium salt addition is difficult to control, place
Reason effect can not meet the needs of directly discharging.
The content of the invention
It is an object of the invention to provide a kind of sanitary sewage dephosphorization agent, by carrying out complex treatment to dephosphorization agent, improves
The effect of processing.
The present invention is achieved through the following technical solutions：
A kind of sanitary sewage dephosphorization agent, including dephosphorization agent A and dephosphorization agent B,
The dephosphorization agent A is made up of following component by weight：6.25 parts of aluminium polychloride, 5.42 parts of attapulgite, sulphur
Sour 2.15 parts of aluminium, 2.36 parts of ferrous sulfate；
The dephosphorization agent B is made up of following raw material by weight：1.85 parts of aluminium polychloride, 6.4 parts of polyvinyl alcohol, sulfuric acid
It is ferrous 2.15 parts.
The attapulgite passes through modification, and processing method is as follows：
（1）, by attapulgite natural air drying, be put into iron pan and carry out frying, frying temperature is at 550-600 DEG C, the frying time
For 10-12min；
（2）, by step（1）The good attapulgite use quality fraction of frying is 10% hydrofluoric acid solution immersion treatment 2-
3h, then washed；
（3）, by step（2）The attapulgite handled well is dried at 35-40 DEG C, then by attapulgite use by sulfuric acid
Aluminium, the sulfuric acid solution of mass fraction 0.5% are by weight 1：The 5 solution immersion treatment 1-2h prepared, ultrasound is used in immersion process
Ripple shakes, and then dries attapulgite, obtains attapulgite modified.After modification, phosphor-removing effect can lift 50-
60 times.
Dephosphorization agent A is used under the conditions of sewage PH is 7.5-8.5, and dephosphorization agent B uses in the case where PH is 6.5-7.5.
Beneficial effects of the present invention：The dephosphorization agent dephosphorization agent A and dephosphorization agent B of sanitary sewage provided by the invention, although former
It is common water treatment agent in material, still, after compounding, under pH condition in this application, the effect of its dephosphorization is significantly
Lifting, high phosphorus sanitary sewage phosphorus content after the processing of the application method can be reduced to 0.25mg/L, at or below national standard.
