Difficulties in the treatment of industrial wastewater


In the transformation of industrial wastewater, the promotion of new technologies is the key. Aside from non-technical factors such as insufficient investment, from the perspective of market effects, the current stage of upgrading and upgrading technology is not enough, not good enough or not enough to promote new technologies. Nowadays, sewage treatment has risen to a national strategy, and the country also attaches great importance to the promotion of advanced technologies. However, the market response of many technologies has been mediocre. Local governments and owners have many concerns. From the perspective of the technology itself, there are some inherent defects. In recent years, what technologies need to be promoted for upgrading and upgrading industrial wastewater, mainly in the following aspects.

1.Some technologies are not true pollution control, but only transfer pollutants from water to mud or air. The later cost is a lot. Now sludge treatment has become a headache in many places, and the risk of secondary pollution is very high.
2.Some technologies are not effective and can only barely meet national standards, and the potential risks of technologies are high.
3.Some technologies have good effects, but either the investment is huge or the operation and maintenance costs are high. From the perspective of long-term operation, the owners cannot afford it.
4.Some technologies have large limitations and cannot meet the requirements of increasingly complex wastewater components, high-concentration wastewater, and wastewater that is difficult to biodegrade.
5.The market performance of some technologies, but relatively new, has not been well promoted or has encountered many problems. For example, using catalysts to deeply treat industrial wastewater from difficult-to-treat industries such as printing and dyeing and papermaking to solve industrial wastewater in industrial parks. The effect is very good and the cost is not high. Moreover, the technology reduces the risk of secondary sludge pollution from the source.

 

Xintan ozone removal/decomposition catalyst is a mixture of copper oxide and manganese dioxide (MnO2 and CuO2 ), which is mainly used to destroy ozone, filter gas mask for breathing, sewage and toxic exhaust deal with. Ozone decomposition catalyst also has the ability to convert CO to CO2. “XINTAN catalyst “ has many successful applications in domestic and foreign cooperations.
