Embodiment Construction
[0026] Such as Figure 1-10 The textile wastewater treatment system shown includes a flocculation sedimentation device 1 , a biological contact oxidation device 2 and an activated carbon adsorption device 3 which are connected in sequence according to the sequence of wastewater treatment. The function of the flocculation and sedimentation device 1 is to perform flocculation and sedimentation treatment on the wastewater after adding the flocculation agent to the wastewater, so as to basically remove suspended solids and impurities in the wastewater. The flocculating agent such as: aluminum sulfate, aluminum chloride, ferric sulfate, ferric chloride, polyaluminum chloride, polyaluminum sulfate, polyferric chloride, polyferric sulfate, etc., the staff can carry out according to the specific type of textile wastewater Reasonable choice. The biological contact oxidation device 2 allows aerobic microorganisms to contact the water body, thereby degrading the residual organic matter ...

The invention relates to the field of textile technology. The purpose is to provide a textile wastewater treatment system with good purification effect. The technical solution adopted in the present invention is: a textile wastewater treatment system, including a flocculation sedimentation device, a biological contact oxidation device, and an activated carbon adsorption device connected in sequence according to the sequence of wastewater treatment; the flocculation sedimentation device includes a flocculation sedimentation box , the flocculation settling tank is composed of a cylindrical stirring chamber and a hydraulic flocculation tank with an open top on one side of the stirring chamber; the lower part of the mixing chamber near the side of the hydraulic flocculation tank is provided with an overflow hole, and through the flow The hole communicates with the inside of the hydraulic flocculation tank; the invention integrates flocculation sedimentation treatment, biodegradation treatment and activated carbon adsorption treatment, and has an excellent treatment effect on textile wastewater. Moreover, in the process of flocculation and sedimentation treatment, the combination of mechanical stirring and hydraulic flocculation ensures the stability of the entire flocculation process and further improves the wastewater treatment effect.
Description
technical field [0001] The invention relates to the technical field of textiles, in particular to a textile wastewater treatment system. Background technique [0002] Textile printing and dyeing wastewater has complex components, often containing a variety of dyes, high chroma, strong toxicity, and poor degradability. It is one of the more difficult industrial wastewater to treat. At present, the main methods for the treatment of textile printing and dyeing wastewater in the prior art include: physical and chemical treatment and biochemical treatment. Physicochemical treatment is a method of treating wastewater by physical methods such as flocculation and adsorption. Commonly used devices such as: coagulation device, activated carbon adsorption device, etc. The biochemical treatment method uses aerobic microorganisms to oxidize and degrade organic matter in wastewater. Commonly used devices such as microbial contact oxidation ponds. Among the above two treatment methods, t...
