Characteristic

1. Reclaimed water treatment equipment can efficiently separate solid from liquid.

2. The residence time is greatly shortened, and the area occupied by bio-anti-rural drinking water equipment responders is reduced accordingly.

3. Make all kinds of metabolic processes in the system run smoothly.

4. The reclaimed water treatment equipment makes the school drinking water equipment with some macromolecule refractory organic matter stay longer, which is conducive to their decomposition.

5. Membrane treatment technology, like other filtration and separation technologies, is blocked by ultrapure water treatment equipment as a filter medium during long-term operation. Effective backwashing and chemical cleaning can slow down the decline of membrane flux and maintain the effective service life of MBR system.

6. The application of MBR technology in municipal wastewater treatment is simple and easy to operate.

Technological process

(1) Pretreatment: also known as primary treatment, generally includes interception; precipitation; water quality and quantity regulation; deoiling; hydrolysis acidification, etc., which has a certain effect on the removal of contaminated impurities in water. Its main role is to ensure the stability of subsequent treatment, and the choice of pretreatment method is based on the physical properties of impurities in raw water.

(2) Secondary treatment: is the main body of water reuse treatment, the main processes are physical and chemical treatment (coagulation and sedimentation process), biological treatment (microbial or plant adsorption and degradation treatment), physical treatment (membrane filtration treatment, etc.), the main role is to remove pollutants in water, according to the type of pollutants in raw water and physicalization. The nature of science determines the use of technology.

(3) Advanced treatment: It is the final treatment of the treated sewage before reuse to ensure water quality and water safety. The main processes include sterilization, ion exchange, media filtration, membrane separation, etc. According to the types and properties of impurities or secondary pollutants that may occur after raw water treatment.

(4) Reclaimed water reuse: It is composed of reclaimed water collection and transportation facilities, which are transported by independent pipelines and directly drinkable water from pipelines; tap water and other clean water supply facilities directly in contact with human body are separated, and no pipelines are allowed to be directly connected to ensure the safety of water use.

(5) Equipment combination: According to the same or similar water quality of some raw water, the treatment process for this kind of water is optimized and made into equipment to produce high-efficiency reclaimed water treatment equipment. For example, the integrated membrane bioreactor for ordinary domestic sewage treatment is to integrate pretreatment (barrier mesh interception), secondary treatment (biodegradation + membrane separation), advanced treatment (sterilization and disinfection) into the whole equipment, and raw water can be directly reused for domestic miscellaneous use after equipment treatment.
