Abstract

A treatment of industrial and urban waste water and its treating equipment are disclosed. The treating equipment consists of TR1, TR2, TR3 and TR4 on-line water-treating units; The process is carried out by paste milling, primary pulp washing, secondary washing, bleaching, potching, flocculation filtering, mechanically filtering, precision filtering, water treating by super-filter, desalting by desalting equipment TR5, adding flocculant into sewage water, bio-chemical polymerization reacting, flocculation free reacting and generating insoluble hydrophilic mass substances. Its advantages include low cost, rational structure, short flocculation time, water circulation utilization and no effluent and environmental pollution. It can be used to bring polluted rivers and lakes under control.

Description

technical field [0001] The invention relates to a water treatment equipment, in particular to a water treatment production equipment for industrial waste water and urban waste water and a process method thereof. Background technique [0002] At present, the paper industry is very harmful to environmental pollution, especially in the pulp production process of paper production. Due to the production processes such as cooking method and oxidation method, a large amount of waste water is produced in the production process. In order to protect the ecological balance, the traditional sewage treatment method is adopted, the efficiency of sewage treatment is low, the investment and operation cost of water treatment equipment are large, and the energy consumption is high, which has led many paper-making enterprises to secretly discharge production wastewater into rivers, rivers, and lakes. Seriously pollute water resources and pollute the environment. In addition, most urban sewage...
