Description

TECHNICAL FIELD

[0001] The utility model relates to industrial sewage treatment technical field especially a flocculating agent adding device for industrial sewage treatment. BACKGROUND

[0002] Industrial wastewater has become one of the main existing wastewater in modern industrial production, and a large amount of industrial wastewater must be effectively treated to remove pollutants in water, reach the corresponding national discharge standard and avoid environmental pollution. Because there are more suspended solids and colloidal particles in wastewater, but the sedimentation and filtration process in the actual production of sedimentation tank can only remove suspended particles within a certain particle size range, so flocculating agent should be added to treat by flocculation and sedimentation, so that the dispersed suspended solids and colloidal particles in wastewater form sediment, and then remove the fine suspended solids and colloidal particles in wastewater.

[0003] The flocculating agent is an important water treatment chemical, which can make the solute, colloid or suspended particles in the aqueous solution unstable and produce flocculation or flocculation precipitate. The flocculating agent can promote the aggregation of the small suspended particles in water to form larger flocs. These flocs have better settling performance due to the increase in volume, so that subsequent sedimentation and separation operations are facilitated. Through the effects of coagulation and sedimentation, the flocculating agent helps to remove turbidity, organic matter, bacteria and other suspended impurities in water. The removal of these impurities can significantly improve the transparency and cleanliness of water, thereby improving water quality. The larger flocs have a faster settling velocity than the small suspended particles. Therefore, the use of flocculating agent can accelerate the settling process of suspended solids in wastewater and shorten the wastewater treatment time.

[0004] In the flocculating agent adding process, the auxiliary adding device can fully play the effect of the flocculating agent.

A plurality of gas lift type filter devices are arranged in the shell. The gas lift type filter device includes a cylindrical filter cotton. An air inlet pipe is coaxially installed in the through hole at the middle part of the cylindrical filter cotton. The diameter of the air inlet pipe is smaller than the inner diameter of the through hole.
