Selection of frame type ultraviolet sterilizer
The integrated buried sewage treatment equipment designed by our company is mainly based on a/o biochemical process, integrating processes such as biodegradation, sewage settling, oxidation disinfection, etc. for domestic sewage and industrial wastewater similar to domestic sewage. The equipment has a compact structure, occupies less land, is all set underground, runs economically, has strong impact concentration resistance, and has high treatment efficiency.
Contact oxidation tank: Sewage flows automatically to the contact tank for biochemical treatment. The contact tank is divided into three stages, with a residence time of 8 hours. (The contact oxidation time of reinforced equipment can reach 8-12 hours.) The filling material is a novel elastic filling material, which is easy to film and does not block. The gas water ratio of the contact oxidation tank is around 1. Secondary sedimentation tank: The biochemical wastewater flows into the secondary sedimentation tank, which is a vertical flow sedimentation tank with a surface load of<1.0m3/m2. The sludge is discharged and lifted to the sludge tank.
Disinfection pool, disinfection device: The disinfection pool should not be less than 30 minutes according to the standard "TJ14-74". If it is hospital sewage, the disinfection pool can increase the residence time to 1-1.5 hours. The disinfection method adopts the contact dissolution of solid chlorine tablets. The disinfection device can continuously change the dosage according to the size of the water output, achieving the goal of adding more water and more medicine, and adding less water and less medicine. Other disinfection devices can be separately prepared if needed.
The sewage treatment equipment system is fully automatic microcomputer controlled and has a fault alarm indication function. Our company's underground sewage treatment equipment adopts internationally advanced biological treatment technology, which integrates the removal of bodcod and nh3-n. It has stable and reliable technical performance, good treatment effect, low investment, small land occupation, and convenient maintenance.
The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in their own oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using fecal trucks to suction or dehydrate into sludge cakes for external transportation). The deodorization method of this buried domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.
The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates reliably and generally does not require dedicated management. Only timely maintenance and upkeep of the equipment are needed. The asphalt paint and glass fiber reinforced plastic are used for corrosion prevention, with excellent characteristics such as corrosion resistance and aging resistance, and the service life is more than 15 years.
The process is complete, the technology is mature, and the cuileifa68 function is stable and reliable. The system generates less sludge, avoiding pollution transfer, saving operating costs and sludge treatment costs. The core anaerobic treatment process adopts the form of UASB reactor, which has a large sludge enrichment capacity, high treatment efficiency, no need to add any chemicals, no need for a large amount of electricity consumption, and low operating costs.
