Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] A comprehensive filtration, sterilization and purification treatment process for industrial waste water of the present invention, said process comprises the following steps:

[0022] (1) Put the wastewater to be treated into a separation container, add flocculant and stir for 7 minutes, and then perform solid-liquid separation to obtain filtrate A;

[0023] (2) The filtrate A is transferred to the sterilization container, adsorbed by sulfur-laden activated carbon, and then sterilized by ultraviolet radiation to obtain the filtrate B; four layers of adsorption layers are set in the sterilization container, and six packs of adsorption layers are installed in each layer. package, and the granular sulfur-loaded activated carbon is placed in eac...

Abstract

The invention discloses a comprehensive filtering, sterilization and purification treatment technology for industrial wastewater. The technology comprises the following steps: (1) putting wastewater to be treated into a separation container; adding a flocculating agent and stirring for 5 to 8min; then carrying out solid-liquid separation to obtain filtrate A; (2) conveying the filtrate A into a sterilization container; adsorbing through sulfur-loaded activated carbon; then carrying out ultraviolet radiation and disinfection to obtain filtrate B; (3) conveying the filtrate B to a membrane filtering container A and filtering to obtain filtrate C; (4) conveying the filtrate C to a membrane filtering container B and filtering to obtain filtrate D; (5) discharging the filtrate D out of the container and washing a separation membrane in the membrane filtering container for one time. According to the comprehensive filtering, sterilization and purification treatment technology for the industrial wastewater, disclosed by the invention, substances, which have influences on the separation membrane, in sewage can be effectively removed and the separation membrane is washed in time so that damages, caused by pollutants, on the separation membrane are reduced and the service life of the separation membrane is easy to prolong; a sterilization procedure can be used for effectively removing toxic substances in the wastewater and the toxicity of the wastewater is greatly removed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a comprehensive filtration, sterilization and purification treatment process for industrial wastewater. Background technique [0002] The shortage of water resources is becoming more and more serious, and more and more people pay attention to the recycling and utilization of water resources in sewage treatment. As an emerging high-efficiency separation method, membrane separation technology has been widely used in food, medicine, textile, electronics, petroleum, water treatment and other fields. Compared with traditional water treatment technology, membrane separation technology is simpler, faster, more efficient and energy-saving. However, the efficiency of sewage treated by the sewage treatment method in the prior art needs to be improved, and the service life of the separation membrane is short. Contents of the invention [0003] In order to overcome the above prob...
