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 and aims at providing a textile sewage purifying system with good purifying effects. According to the technical scheme, the textile sewage purifying system comprises a flocculent precipitation device, a biological contact oxidation device and an activated carbon absorption device which are sequentially communicated in a sewage treatment order, wherein the activated carbon absorption device comprises an absorbing tube vertically arranged, the bottom center of the absorbing tube is provided with an absorbing water inlet pipe which is communicated with the biological contact oxidation device through a water pipe, and the water pipe is provided with a water pump and a check valve; the upper portion of one side of the absorbing tube is provided with a tail end water outlet pipe. The textile sewage purifying system integrates flocculent precipitation treatment, biodegradation treatment and activated carbon absorption treatment to achieve good treating effects on textile sewage; meanwhile, the textile sewage purifying system improves the absorbing effects of activated carbon on hazardous materials and greatly improves the effluent cleanliness of the tail end water 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...
