Embodiment Construction

[0027] Such as Figure 1-10 The textile sewage purification system shown includes a flocculation and 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 matt...

Abstract

The invention relates to the field of textile technology. The purpose is to provide a textile sewage purification system with good purification effect. The technical solution adopted in the present invention is: a textile sewage purification 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 activated carbon adsorption device includes a vertically arranged An adsorption cylinder, the center of the bottom of the adsorption cylinder is provided with an adsorption water inlet pipe, and the adsorption water inlet pipe communicates with the biological contact oxidation device through a water delivery pipeline, and a water pump and a check valve are arranged on the water delivery pipeline; one side of the adsorption cylinder The upper part is provided with a water outlet pipe at the tail end. The invention integrates flocculation and sedimentation treatment, biodegradation treatment and active carbon adsorption treatment, and has excellent treatment effect on textile wastewater. It improves the adsorption effect of activated carbon on harmful substances, and greatly improves the cleanliness of the outlet water at the end of the outlet pipe.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a textile sewage purification 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, th...
