Abstract
The invention discloses a kind of coagulant for handling domestic waste water, include the raw materials of following parts by weight:20 30 parts of diatomite, 15 20 parts of ferric sulfate, 22 29 parts of magnesium sulfate, 35 40 parts of flyash, 26 30 parts of polyacrylamide, 10 25 parts of aluminium polychloride.Present invention processing domestic waste water coagulant is different from traditional single type coagulant, diatomite, ferric sulfate, magnesium sulfate, flyash are incorporated into common polyacrylamide coagulant, make to form new valence bond structure between diatomite and flyash, further increase coagulation effect, so as to have good treatment effect, suitable popularization and application to the total nitrogen in waste water, total phosphorus and COD.
Description
Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of coagulant for handling domestic waste water.
Background technology
Domestic waste water is one of main wastewater source in China, and the improvement of domestic waste water is also that water treatment field needs emphasis to examine
The problem of worry.Specifically, nitrogen-containing compound such as nitrite nitrogen, nitrate nitrogen, inorganic salts nitrogen, dissolved nitrogen in domestic waste water
Etc. causing, nitrogen pool in family domestic waste water is higher, in addition, total phosphorus content is also very high in domestic waste water.Both pollutants are families
How the main source of front yard Pollutants in Wastewater, effectively reduce Determination of Total Nitrogen in Waste Water and total phosphorus content has become us and is badly in need of solving
The problem of.
The content of the invention
It is an object of the invention to provide a kind of coagulant for effectively reducing nitrogen phosphorus and the processing domestic waste water of COD contents.
The technical solution for realizing the object of the invention is：
A kind of coagulant for handling domestic waste water, include the raw material of following parts by weight:Diatomite 20-30 parts, ferric sulfate 15-
20 parts, magnesium sulfate 22-29 parts, flyash 35-40 parts, polyacrylamide 26-30 parts, aluminium polychloride 10-25 parts.
Preferably, the coagulant includes the raw material of following parts by weight:25 parts of diatomite, 18 parts of ferric sulfate, magnesium sulfate 26
Part, 38 parts of flyash, 27 parts of polyacrylamide, 19 parts of aluminium polychloride.
Compared with prior art, its remarkable advantage is the present invention：
Present invention processing domestic waste water coagulant is different from traditional single type coagulant, by diatomite, ferric sulfate, sulfuric acid
Magnesium, flyash are incorporated into common polyacrylamide coagulant, make to form new valence bond structure between diatomite and flyash,
Coagulation effect is further increased, it is suitable to promote so as to have good treatment effect to the total nitrogen in waste water, total phosphorus and COD
Using.
Embodiment
The present invention is described in further detail with reference to specific embodiment.

29 parts of magnesium sulfate, 40 parts of flyash, 26 parts of polyacrylamide, 25 parts of aluminium polychloride.
Embodiment 3
A kind of coagulant for handling domestic waste water, the coagulant include the raw material of following parts by weight:25 parts of diatomite, sulphur
Sour 18 parts of iron, 26 parts of magnesium sulfate, 38 parts of flyash, 27 parts of polyacrylamide, 19 parts of aluminium polychloride.
Embodiment 4
A kind of coagulant for handling domestic waste water, include the raw material of following parts by weight:23 parts of diatomite, 15 parts of ferric sulfate,
29 parts of magnesium sulfate, 38 parts of flyash, 28 parts of polyacrylamide, 25 parts of aluminium polychloride.
The domestic waste water that 4 parts of water quality phase homogenous quantities are 1kg is taken respectively, and it is 115mg/L that before processing, which measures total values of nitrogen might, total phosphorus value
For 123mg/L, inorganic agent in tri- groups of embodiments of 100g is separately added into 4 parts of waste water, after stirring, stand 1h, measure total values of nitrogen might,
Total phosphorus value and COD results are as follows：
| Before processing | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | |
| Total values of nitrogen might | 115 | 8.5 | 9.4 | 5.3 | 6.7 |
| Total phosphorus value | 123 | 9.5 | 7.9 | 4.8 | 8.4 |
| COD | 308 | 75 | 79 | 63 | 80 |
