★Scope of application

Applicable to wastewater treatment in the printing and dyeing and textile industries

★Main technical parameters

Influent CODcr 600--800mg/L; Effluent CODcr 60--100mg/L; Effluent meets the national sewage discharge standard GB8978-1996, GB4287-92 first-level discharge standard.

★Technical features

The principle of hydrolysis and acidification is to decompose organic matter that is difficult to degrade under aerobic conditions through anaerobic hydrolysis and acidification microorganisms, and to improve the B/C of wastewater to facilitate the operation of subsequent aerobic biological treatment. Hydrolysis and acidification abandon the methane production stage in the anaerobic digestion process, which has very strict requirements on environmental conditions and slow microbial proliferation. The volume of the anaerobic treatment device is greatly reduced, and the gas recovery and utilization system is eliminated. The hydrolysis and acidification contact oxidation method has low operating costs and good treatment effects.

★FAQ

Q. What are the common sewage treatment processes?
A. Common sewage treatment processes include activated sludge method (such as A²/O, oxidation ditch, SBR), biofilm method (such as biofilter, biorotor), membrane bioreactor (MBR), etc. These processes mainly use physical, biological and chemical means to remove organic matter, suspended solids, nitrogen and phosphorus and other pollutants in sewage to achieve standard discharge or water resource reuse.

Q. How is the sludge generated during sewage treatment handled?
A. The sludge generated during sewage treatment needs to be concentrated, dehydrated, stabilized (such as anaerobic digestion) and other treatments to reduce the volume and reduce pollution. The treated sludge can be used as a resource, such as fertilizer, incinerated for power generation, or landfilled. Reasonable disposal of sludge is an important part of ensuring that the entire sewage treatment process meets environmental standards.

Q. Does the sewage treatment plant have a bad smell? How to control the odor pollution?
A. Sewage treatment plants may produce bad smells at water inlets, grit chambers, sludge treatment areas and other places. In order to control the odor pollution, deodorization measures such as sealing facilities, negative pressure collection, chemical washing, biological filters or activated carbon adsorption are usually adopted, and the plant area is reasonably laid out and green belts are set up to reduce the impact on the surrounding environment.
