The typical treatment process flow is as follows: Xinqi Chemical 12bet online betting website Wastewater Screen Collection Tank Air Flotation or Sedimentation Discharge Air flotation and sedimentation are both physical and chemical treatment methods，Processing effects and equipment selection、Process parameters、Coagulant, etc.，The COD removal rate is generally higher than that of the water in the middle section of pulping，Usually can reach 70%~85%。Wastewater discharge per ton of paper＞150m3、Small and medium-sized waste paper manufacturing enterprises with low concentration，Through flotation or sedimentation，The effluent water quality index can reach or be close to the national discharge standards。 Notes: 1、Solution temperature。Dissolution requires a certain temperature，To speed up dissolution。But the temperature is too high，It will break the molecular chain of the polymer，Reduce usage effect，The more suitable dissolution temperature is below 60。 2、Stirring conditions。Dissolution should avoid excessive shear force and stirring，Excessive stirring will break the molecular chain，Thus reducing the use effect。It is advisable to use low-speed paddles for mixing，such as anchor、Frame style、Multi-layer pulp type, etc.。The stirring speed is about 60 rpm。 High-speed centrifugal pumps should also be avoided during transportation，It is more suitable to use piston pump or diaphragm pump。 3、Evenly dispersed feeding。Key steps in dissolving 12bet online betting website ，It is the uniform dispersion of the feed。After starting the mixer， It is best to use a mechanical vibrating screen to feed materials (the screen mesh is 10 mesh)，Try to avoid “big clumps”、“Fish-eye-shaped” insoluble particles，So that 12bet online betting website can be fully dissolved，Get the most out of it。 4、Avoid contact with iron。In the dissolving, stirring and conveying and dosing system，Better to use plastic、Enamel、Aluminum、Stainless steel and other materials。
