DGSB®
DGSB® — Denitrifying Granular Sludge Blanket
Process introduction:
DGSB ® It is an efficient anaerobic reactor for denitrifying granular sludge bed technology. In response to the problems of low sludge concentration, low volumetric efficiency, and large reactor volume in traditional biological denitrification processes, the design involves adding floating denitrifying granular sludge to the downward flow granular sludge bed DGSB ® Starting from the middle, the container load and denitrification efficiency are 10 times higher than those of ordinary bioreactors.
Technological advantages:
1. High volumetric efficiency
·The device has high volumetric efficiency, with a maximum volumetric load of 70 kg-N/(m3 · d) and a total nitrogen removal rate of up to 98%;
·High concentration shock load resistance, with a maximum influent nitrate concentration of up to 2000 mg-N/L;
2. Excellent economic performance
·Miniaturization of process equipment, simple structure, stable effect, saving equipment costs and land occupation costs, and reducing engineering investment;
·Low operating costs, utilizing self generated gas for self stirring, eliminating the need for traditional mixers/thrusters for denitrification;
·The bacterial body exists in the form of granular sludge, and the separation effect of sludge and water is good, which can reduce engineering equipment.
Application scope:
High concentration nitrate and nitrite wastewater treatment in industries such as photovoltaic and stainless steel manufacturing.
