Characteristics of industrial wastewater
-
-
-
The pollution hazards caused by industrial wastewater to the environment, and the prevention and control measures that should be taken, depend on the characteristics of industrial wastewater, that is, the type, nature and concentration of pollutants. The water quality characteristics of industrial wastewater vary not only according to the type of wastewater, but often change with time and place.
-
The characteristics of industrial wastewater are mainly manifested in large discharge volume, complex composition and serious pollution. The two most important pollution indicators are commonly used to express the quality of wastewater, that is, suspended solids and chemical oxygen demand. The water quality of different industrial wastewater varies greatly. Taking chemical oxygen demand as an example, the lower is between 250-3500 mg/L, and the higher is often tens of thousands of milligrams per liter, or even hundreds of thousands of milligrams per liter.
industrial wastewater treatment solutions
Choose the appropriate treatment process and related equipment according to the waste water volume and water quality. Ensure that the sewage can be effectively treated to reach the discharge standard, and it can save energy consumption and economic investment.
Part of the required equipment
-
-
Dissolved air flotation machine
-
The dissolved gas system generates a large number of micro-fine bubbles in the water. Several bubbles adhere to the surface of the flocculated impurity particles in the water to form a state with a density less than that of water. The buoyancy makes it rise to the surface of the water, thereby achieving solid-liquid separation and removing waste water. The fine suspended solids and grease in.
-
Product features: ● The dissolved air tank produces tiny bubbles, adheres to flocs firmly, and has a good air flotation effect.● The amount of flocculant used is small and the cost is reduced. ● Water quality and quantity are easy to control, and operation and management are simple. ● Equipped with backwashing system, the releaser is not easy to be blocked.

-
Quartz sand, activated carbon filter
-
The filter can filter and adsorb pollutants such as small molecular organics to improve the quality of the effluent. It has a strong adsorption and removal effect on peculiar smell and pigment in wastewater, and it also has the effect of reducing COD.
-
Product features：● High efficiency, continuous operation, no need to stop for backwashing. ● Small footprint and low operating cost. ● The effluent quality is stable, and the filtering and adsorption effects are good.
