Integrated sewage treatment equipment is applicable to domestic sewage in residential quarters, towns, office buildings, shopping malls, business hotels, nursing homes, administrative organs, colleges, hospital clinics, highways, railway lines, factories and mining enterprises, tourist attractions, and other large, medium and small industrial production organic wastewater from slaughter, aquatic processing Organic wastewater from food and other large, medium and small industries. The waste water body before the machine and equipment are solved can meet the Class I and Class B specifications in the environmental protection standards for comprehensive wastewater treatment in China.
Integrated sewage treatment equipment can be divided into general integrated machinery equipment and MBR integrated sewage treatment equipment. A/O/biological touch oxidation method is selected for general integrated machinery and equipment, which is also called "submerged biological filter", "touch hydrolysis acidification tank method" and "fixed activated sludge". The technical principle is to add fillers in the biological reaction tank, and the oxygenated wastewater will swallow all the fillers, so that a certain flow speed can pass through the fillers.
The biofilm is covered on the filler, and the waste water is fully touched with the biofilm. Under the metabolism in the biofilm, the organic pollutants in the wastewater can be removed, and the wastewater can be purified and treated.
MBR membrane The integrated sewage treatment equipment selects membrane separation equipment to replace the traditional secondary sedimentation tank processing technology to carry out mud water separation. The membrane system software is closely integrated with the biological treatment unit, and the sludge composition can achieve multiple times of the basic processing technology. The sludge has long age and low load, which is beneficial to dissolving organic compounds and permanganate index in sewage.
MBR membrane integrated sewage treatment equipment has the following advantages:
1. It can reasonably separate suspended solids, colloidal solution chemicals and beneficial microorganisms in water by chromatography. The separate processing technology is simple, the total area is small, and the overflow water body is good. Generally, recycling can be carried out without tertiary treatment.
2. The microorganism in the biological treatment unit can be maintained at a higher concentration to further increase the capacity load. At the same time, the effective characteristics of membrane separation technology greatly shorten the water retention time of the treatment unit and reduce the total area of the biological reactor.
3. The flow of beneficial microorganisms is small, which is beneficial to the growth and development of slow growing water quality stabilizers, etc., so that the whole process of multiple metabolism in the system software can be carried out smoothly.
4. The residence time of some insoluble organics in polymer materials is very long, which is beneficial to their dissolution.
5. MBR integrated sewage treatment equipment is the same as other filtration separation technologies. In the case of long-term operation, the membrane is blocked as a filter material, and the running time of the membrane in water is slowly reduced. Reasonable backwashing and chemical water treatment can restore the membrane diffusion coefficient and maintain the reasonable service life of MBR system software.
6. The key technology of MBR membrane is applied to urban sewage treatment. The processing technology is simple and the actual operation is convenient, which can complete the automatic technology operation and management method.
7. The use of spray paint for external paint is beneficial to the customer's overall planning and reasonable layout, and changes the past perception of sewage treatment equipment.
8. The MBR film of tablet computer is selected, which will not be broken, and has excellent impact toughness. The internal structure of the film layer uses no anti cloth as the applicable layer, with good wear resistance. The flat membrane is very easy to replace, and the damaged pulse damper can be replaced automatically.
