Abstract

The invention relates to an industrial wastewater and municipal wastewater processing method. The sewage treating apparatus comprises: TR1, TR2, TR3 and TR4 on-line water processor units which grind pulp in the pulping process and in the primary and second pulp washing process; a flocculating filtration apparatus, a mechanical filtration apparatus, a secondary filtration apparatus and a hyperfiltration apparatus which process the water in the bleaching and rinsing process; and a desalinisation processing apparatus TR5 which ensures the final desalinisation of the circulating water. The processing method changes the fluid form in the whole process after adding the flocculant in the wastewater. In the biochemical polymerization reaction and mechanical physical movement process, the polluting factors rapidly generate the flocculation dissociation in the flow process, thus making the tiny microparticle impurities generate the agglomerate which is convenient for filtration, hydrophilic and insoluble and dewatering the pollutant to be sorted into dry matters. The invention has the advantages of low equipment investment, no waste liquid discharge and remarkable economic benefit. The processed water is used in cycle. The invention is applied to paper-making pulping, municipal wastewater and industrial wastewater process.

Description

[0001] This application is a divisional application. The filing date of the original application is: 2005.2.30, the application number is: 200510003422.5, and the invention name is: industrial wastewater and urban wastewater treatment equipment and its process method. technical field [0002] The invention belongs to the field of water treatment, in particular to a process method for treating industrial waste water and urban waste water. Background technique [0003] At present, the harm caused by the paper industry to environmental pollution is very obvious, especially in the pulp production link of paper production, due to the production processes such as cooking method and oxidation method, a large amount of waste water will be generated in the production process. Using traditional sewage treatment methods, the efficiency of sewage treatment is low; the investment and operation costs of water treatment equipment are large; the energy consumption is high, which has led many...
