Environmental Protection in Production Process of Diamond Micro-powder

In the production process of diamond micro-powder, there is an acid and alkali treatment for raw materials and products, which will emit harmful gases and waste water that will harm operators and pollute the environment. In order to protect everyone’s health and ecological balance, there are prescribed discharge standards on harmful substances in industrial waste gas and waste water in National Environmental Protection Regulations. Only reaching the corresponding standard can waste gas and waste water be allowed to discharge.

In the acid treatment of diamond micro-powder, it will produce harmful gases such as chlorine, nitrogen oxides and sulfur oxide. Some large micro-powder enterprises have special rooms for acid and alkali treatment, and there are also special ventilation cabinet that will discharge waste gas to enter cooling tower. And through several processing to achieve discharge standards, they will be allowed to discharge.

In 2009, a company introduced a complete set of wastewater filtration system that is international advanced environmental protection energy conservation and emissions reduction, and used multiple sets of enclosed acid treatment devices in Henan province. Each tank can be invested tens of kilograms of diamond raw materials or single number micro-powder particle size. Waste gas produced in acid treatment need to be processed in the indoor and cooling tower, and then outdoor and cooling tower for the second neutralization process, to achieve the discharge standards.

This process makes inside and outside of workshops smell no sour, which really achieves the protection of environment, pollution-free diamond micro-powder processing technology. It provides an implementation of the ecological balance in micro-powder production and pollution-free exemplary role for superhard material industry.
