Abstract

The invention belongs to the technical field of environment protection, and in particular relates to an automatic adding system of powdered activated carbon. The automatic adding system of the powdered activated carbon, which is provided by the invention, comprises a two-stage TJPP serial pneumatic conveyor of the powdered activated carbon, a precise powder feeder, a PHM serial liquid-powder mixer, a storage chamber, a corresponding automatic control system and accessories. Or the automatic adding system of the powdered activated carbon can comprise a one-stage TJPP serial pneumatic conveyor of the powdered activated carbon, a precise powder feeder, a liquid-powder mixer, a corresponding automatic control system and accessories. The automatic adding system of the powdered activated carbonhas simple structure, special design, simple and convenient installation, low noise, economy and rationality, can be widely applied to feedwater treatment and waste water treatment, can relieve the labor intensity of operators and the pollution of the powdered activated carbon to the environment, ensures the adding precision of the powdered activated carbon, and has higher working stability and reliability.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to an automatic powder activated carbon dosing system. Background technique [0002] Powdered activated carbon (PAC) has been used in water supply treatment for about 70 years. The main features of powdered activated carbon application are low equipment investment, fast adsorption speed, and strong adaptability to short-term and sudden water pollution. Powdered activated carbon is used for tap water treatment not only to effectively remove most of the organic matter and some inorganic matter in sewage, but also to remove trace organic pollutants such as odorants, algae toxins, disinfection by-product precursors and pesticides in raw water. Water supply treatment has become an effective means of advanced treatment and micro-polluted water treatment. The country pays more and more attention to environmental protection work, environmental discharge standards are...
