Description
Technical field
The present invention relates to technical field of sewage, particularly relate to waste water treating agent and the preparation side thereof of a kind of smelting iron and steel
Method.
Background technology
Sewage-treating agent as the term suggests need exactly a kind of additive used when sewage disposal, as polyacrylamide,
PAMC, PAMA, nonionic, amphion polyacrylamide, aluminium polychlorid etc. are not
Can use as sewage-treating agent with in purposes.
In the sewage disposal system using the various inorganic coagulant such as aluminium salt, iron salt, flocculant, if desired for the water processed
Amount has exceeded the disposal ability of depositing reservoir or has floated outward owing to other factors cause flco in water to have little time sedimentation, only needs to add
The PAM of 0.1-2ppm helps solidifying, can significantly improve effect of settling.And, after process, COD and the chromaticity index of water also have substantially
Improvement.
Use 0.3-2ppm can reduce mud and the ratio of water in biochemistry pool and sludge concentration tank, improve biochemistry pool
Utilization rate with sludge concentration tank.Sludge concentration can be brought up to 30--100 g/L by 3---10 g/L, substantially reduce next
The mud body weight of the process of step sludge dewatering, improves device for dehydrating sladge waste and personnel's effective percentage.
In recent years, the crisis of facing mankind water had been undisputable fact.China adds urban infrastructure construction and ring
The input of border protection, strengthens comprehensive environmental improvement, so that gross contamination emission is effectively controlled, some areas and city
