Biochemical Treatment Technology of High Salt Wastewater
The continuous interaction in the live broadcast room is soaring
Q: Will the packing of your company have a problem of hardening, and will it cause sludge deposition after hardening, so that there is less sludge on the packing section?
A: Our company's packing has a special surface structure design, which can effectively prevent the problem of packing compaction. At present, the packing used in the project has not been compacted.
Q: For the multi-stage packing technology + post-air flotation combined process mentioned by your company, whether the dissolved oxygen carried by the sludge return in the post-air flotation will affect the effect of the anaerobic or anoxic process in the previous stage, and how to control it?
Answer: The combination process we mentioned is a recommended combination process. For the biochemical process with only aerobic section, this combination process has great advantages for projects with tight floor space; the front section has anaerobic or anoxic process reflux The subsequent dissolved oxygen control is calculated and confirmed in detail according to the pollutant concentration parameters, sludge concentration and reflux ratio of the specific process.
Q: What are the advantages of your company's multi-stage packing technology process operating costs?
Answer: The main operating advantage of this process is the reduction of sludge volume, especially for some industries that generate hazardous waste sludge or enterprises with high sludge treatment costs in the region, it has considerable advantages in reducing sludge treatment costs. .

WT-MSABP aerobic biochemical treatment technology has the characteristics of high treatment load, sewage salt tolerance<4% (calculated as sodium chloride), strong impact resistance, small footprint, and small amount of excess sludge. It is suitable for wastewater treatment. High-efficiency treatment of organic wastewater and refractory organic wastewater in high-salt environment of oxygen biochemical system, as well as upgrading and expansion without increasing the land occupation and investment of civil works.
