Common pharmacy With reasonable water treatment process and deep treatment with water, the treated water can reach GB5084-1992, CECS61-94 water recycling water standard, etc., can be recycled for a long time, saving a lot of water resources. The following are commonly used pharmaceuticals for wastewater treatment: (1) Flocculant: Sometimes called coagulant, it can be used […]

Approach 3.Biological treatment Through the metabolism of microorganisms, the wastewater, which is a solution, a colloid and a micro-suspended organic pollutant, is converted into a stable and harmless substance wastewater treatment method. According to the different microorganisms, the biological treatment method can be divided into two types: aerobic biological treatment and anaerobic biological treatment. Aerobic […]

Approach 1.Physical processing The method of separating and recovering undissolved suspended state pollutants (including oil film and oil beads) in the wastewater by physical action can be classified into a gravity separation method, a centrifugal separation method, and a sieve filtration retention method. The processing unit belonging to the gravity separation method has sedimentation, floating […]

Wastewater type Industrial wastewater B.heavy metal wastewater Heavy metal wastewater mainly comes from wastewater discharged from mines, smelting, electrolysis, electroplating, pesticides, medicine, paints, pigments and other enterprises. If the heavy metal wastewater is not treated, it will seriously pollute the environment. The types, contents and forms of heavy metals in wastewater treatment vary with different […]

Wastewater type Industrial wastewater Many types of pollutants are produced in industrial production, and the types and concentrations of pollutants produced by different industries are significantly different. A . electroplating wastewater The main source of zinc in electroplating and metalworking wastewater is electroplated or pickled tow. The contaminants are transferred to the rinse water by […]

Wastewater treatment methods use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and even achieve wastewater recovery, reuse, and full use of water resources. Wastewater type Domestic wastewater Domestic sewage refers to the wastewater discharged by people in daily life activities. This kind of wastewater is mainly polluted by domestic waste […]

A power plant that uses coal, oil, and natural gas to generate electricity is called a thermal power plant, and a thermal power plant that generates electricity and heat is called a thermal power plant (also called a thermal power plant). Thermal power plants can make full use of the waste heat released by power […]

The loss on ignition test method has different regulations in the technical standards of different industries. For example, the test method for the loss on ignition of ash formed by combustion is as follows: accurately sample 0.5~1 which has been dried at 105~110 °C. Gram, placed in a constant weight platinum crucible, burned on an […]

Definition Loss of ignition (LOI Loss on ignition) refers to the raw material that loses external moisture after drying in the temperature range of 105-110 ° C. The mass lost after burning for a long time under certain high temperature conditions accounts for the mass of the original sample. percentage. The high temperature environment here […]
