Although China has made great achievements in wastewater treatment, the zero discharge treatment of wastewater still needs to be broken through in the future, and many environmental protection enterprises strive to achieve the goal of zero discharge. The National Environmental Statistics Bulletin released data at the end of October 2015: in 2014, the total amount of wastewater discharged nationwide was 71.62 billion tons, including 20.53 billion tons of industrial wastewater and 1.03 billion tons of urban domestic sewage. The huge amount of wastewater discharge will directly affect the quality of the water environment, which will inevitably affect our quality of life.
The paper industry will produce a lot of wastewater and sewage. The organic matter in the wastewater accounts for 25% of the total organic matter in China's domestic industrial wastewater, which has a very serious impact on the natural ecological environment. Therefore, it is necessary to reduce the wastewater discharged by the paper industry, so as to achieve zero discharge of paper wastewater. In order to ensure the production increase and emission reduction of the papermaking industry, it is also necessary to promote the zero discharge of papermaking wastewater, which can not only improve the economic benefits of the papermaking industry, but also achieve the goal of energy conservation and emission reduction, and form better social and environmental benefits. This is also in line with the concept of sustainable development proposed by today's society.
Environmental protection is an increasingly important topic. On the basis of green and sustainable development, Lightrider has a leading and reliable zero discharge treatment technology, which can achieve zero discharge of wastewater from industrial parks, chemical enterprises and other industries. As far as the well-known organic wastewater discharged by pharmaceutical and chemical enterprises is concerned, the cost of treating a ton of high concentration organic wastewater is about 120 yuan, while the high concentration organic wastewater treatment system produced by Lightrider can reduce the treatment cost by more than half. Zero discharge of electroplating wastewater It solves the problem of high cost of enterprise wastewater treatment, and makes positive contributions to environmental protection. The first generation of sewage treatment system, which has condensed the efforts of scientific researchers, has realized industrialization.
Pulp and paper making will produce a lot of wastewater. There is also a high BOD in the papermaking wastewater, and there are a lot of fiber suspended solids in the papermaking wastewater. In addition, the papermaking wastewater contains divalent sulfur and discoloration, which will have a very serious pollution and impact on the natural ecological environment. The waste water also contains black liquor and white water, so it is necessary to effectively clean up the impurity content in the waste water. Reducing the impurity content in the waste water not only meets the environmental protection requirements, but also can improve the social and economic benefits.
