Advanced electro-catalytic oxidation device
Advanced electro-catalytic oxidation device means that under the action of electric field, the modifiers existing on the electrode surface or solution phase can promote or inhibit the electron transfer reaction on the electrode, and make toxic and harmful pollutants become non-toxic and harmless substances, or form precipitates or generate gases to escape, so as to achieve the purpose of removing pollutants.
Dissolved air floatation integrated machine
The main treatment process of the air flotation and sedimentation integrated machine adopts physical and chemical methods. The traditional mature technology such as chemical method, air flotation method, filtration and adsorption method is designed through organic combination. It has the characteristics of simple and reasonable process, wide adaptability, compact structure, convenient transportation and installation, simple operation, stable and reliable performance. It has a good effect on oil-water separation, suspended solids, COD, BOD removal, and general wastewater can meet the discharge standard after treatment.
Inclined tube sedimentation device
Inclined tube precipitator refers to the sedimentation equipment with inclined tubes in the sedimentation area. In the sedimentation area of the horizontal or vertical sedimentation tank, inclined parallel pipes or parallel pipes (sometimes honeycomb packing can be used) are used to divide into a series of shallow sedimentation layers, and the treated and settled sediments move and separate from each other in each shallow sedimentation layer. According to their mutual movement direction, they can be divided into three different separation modes: reverse (opposite) flow, co-current flow and lateral flow. Every two parallel inclined plates (or parallel pipes) is equivalent to a very shallow sedimentation tank.
AO integrated machine device
A/O process, also called anaerobic-aerobic process, is mainly used in water treatment. A is the anaerobic section, which is mainly used for nitrogen and phosphorus removal; O is aerobic stage, which is mainly used to remove organic matter from water. It can not only remove organic pollutants in wastewater, but also remove nitrogen and phosphorus at the same time. For high-concentration organic wastewater and refractory wastewater, a hydrolysis acidification section is set before the aerobic section, which can significantly improve the biodegradability of wastewater.
