Structure of the invention is reasonable, easy to use, can clear up bottom of pond and the water surface, will be on the sundries of bottom of pond, the water surface
Floating material, COD, ammonia nitrogen and residual liquid medicine carry out thorough cleaning, the cultivating system of the effective solution prior art existed
Filter the technical problem of effect difference.
Embodiment 2
A kind of adsorbent is prepared according to following technique:
Palygorskite is crushed, progress ball milling 12h in ball mill is then put into, stops ball milling, cross 200 meshes, collect screenings,
Obtain component A；
Zeolite powder, diatomite, bentonite and water are mixed evenly according to the mass ratio of 5:2:3:10, obtain component B；
Component A, component B, ammonium hydrogen carbonate and urea are put into blender according to the mass ratio of 10:30:1:1,300rpm
5min is stirred, mixed material is obtained, then puts into pelletizer and be granulated, the sphere that partial size is 5mm is made；It will be spherical
Object is placed in 80 DEG C of baking oven dry 60min, then is calcined, 600 DEG C of calcination temperature, and 30min is kept the temperature, and takes out, natural cooling
To room temperature, adsorbent is obtained.
Waste water index: COD 612.9mg/L, ammonia nitrogen 115.6mg/L, terramycin 1358.1ug/L, sulfa antibiotics
65.3ug/L,
Control group selects conventional active carbon and polyacrylamide respectively；Each group adsorbent handles the time as 2h, and dispensing ratio is
Waste water per ton adds 50g；Treated, and water parameter index is shown in Table 1:
Table 1
| Group | The present invention | Active carbon | Polyacrylamide |
| COD mg/L | 38.9 | 89.6 | 154.1 |
| Ammonia nitrogen mg/L | 14.9 | 43.2 | 38.7 |
| Terramycin ug/L | 34.1 | 234.6 | 289.1 |
| Sulfa antibiotics ug/L | 6.5 | 18.4 | 37.2 |
