Overview

The manufacturer of ecological sewage treatment equipment in the scenic area has installed elastic fillers in the anoxic tank to intercept small suspended solids in the sewage and remove some organic matter. The nitrification solution after reflux in the anoxic tank is subjected to denitrification and denitrification, which improves the removal rate of ammonia nitrogen in wastewater. The sewage treated with hypoxia enters the aerobic biological treatment tank.

The level of economic development in our country varies greatly from place to place, and cities with lagging economic development cannot allocate a lot of funds for sewage treatment. Therefore, how to use limited funds to reduce environmental pollution is a problem faced by many city governments. In terms of sewage treatment, until recently, some cities still adopted first level or first level enhanced treatment technology, and the effluent did not meet the requirements of the national second level discharge standards for removing organic pollutants. The cyclic intermittent aeration process fully utilizes the advantages of high efficiency in high load oxidation ditch treatment and the good effluent quality of the sequencing batch activated sludge sewage treatment process, ensuring that the system effluent meets the requirements of the national sewage discharge level one standard in removing organic pollutants. It is a process technology suitable for China's current sewage treatment requirements, which reduces investment and operating costs by about 30% compared to the typical secondary biological sewage treatment system that mainly removes organic pollutants.

The process selection mainly adopts the treatment process of "anaerobic biochemistry+biological contact oxidation+disinfection".

Regulating tank: After pre-treatment, the combined sewage flows automatically to the regulating tank after removing large floating particles through a grid. The water quality and quantity are homogenized in the regulating tank, and the temperature, concentration, pH value, etc. are adjusted by themselves. Then, it is pumped to the anaerobic tank;

Anaerobic tank: After being utilized by polyphosphate accumulating bacteria and denitrifying bacteria, the concentration of organic matter is already very low, which is conducive to the growth and reproduction of autotrophic nitrifying bacteria. The main function is to remove nitrogen.

Contact oxidation tank: Contact oxidation tank is a biochemical treatment device mainly composed of biofilm and also containing activated sludge. Most of the organic matter in sewage is degraded and purified here. Aerobic bacteria use fillers as carriers and utilize the organic matter in sewage as nutrients to decompose it into inorganic salts, thereby achieving the purpose of purification.

The survival of aerobic bacteria requires sufficient oxygen, that is, there is enough dissolved oxygen in sewage to achieve the purpose of biochemical treatment.

Maintenance and upkeep of equipment:

1. The equipment is designed and manufactured with a compact structure, small size, convenient transportation and installation, short construction period, and small footprint. The initial investment cost is low.

2. Strong impact resistance and stable effluent quality. Adopting MBR flat membrane bioreactor treatment process, the effluent effect is good.

3. Adopting the A/O process, aeration devices are installed in both tank A and tank O, with controllable aeration to eliminate the generation of odorous gases in tank A. The treatment is flexible, greatly improving the volumetric efficiency of the equipment, resulting in better effluent quality, no odor, and improved operating environment.

4. The electric cabinet adopts anti condensation, high temperature resistance design, and fan noise isolation and heat dissipation design. The electrical equipment has strong anti-aging ability, which is more suitable for outdoor scenic spots.

5. Easy to operate and maintain, no need for professional personnel management, and can achieve unmanned operation.

6. The equipment is equipped with a smart water management platform to remotely detect water quality data.

Most of the organic matter in the original sewage of the integrated sewage treatment equipment is degraded and purified here. Aerobic bacteria use fillers as carriers and utilize the organic matter in the sewage as food to decompose it into inorganic salts, thereby achieving the purpose of purification. The survival of aerobic bacteria requires sufficient oxygen, that is, there is enough dissolved oxygen in sewage to achieve the purpose of biochemical treatment. The air in the aerobic tank is provided by a fan, and a new type of semi soft biological packing material is used in the tank. The packing material has a large surface area ratio, long service life, easy film formation, and corrosion resistance. The bottom of the tank is equipped with a microporous aerator, which increases the transfer rate of dissolved oxygen. At the same time, it has the advantages of light weight, non aging, non clogging, and long service life.

Adopting biofilm method: anaerobic aerobic (A/0) treatment process. A/O, also known as anaerobic+aerobic biological contact oxidation, is a mature biological treatment process that has the advantages of high volumetric load, fast biodegradation rate, small footprint, low infrastructure investment and operating costs. It can replace the ordinary activated sludge method used in urban sewage treatment and is particularly suitable for the treatment of medium and high concentration industrial wastewater, with low investment, small footprint, and high treatment efficiency. This process adopts a combination of biological contact oxidation and precipitation, and is mature and reliable. Sludge is precipitated in the equipment, and a portion of the sludge is further oxidized and decomposed due to the action of dissolved oxygen, while another portion is lifted into the sedimentation tank. The system sludge only needs to be regularly pumped in the sedimentation tank. The working program of the main control equipment such as the wind turbine and submersible sewage pump in the system is input into the PLC machine to achieve automatic operation, reduce the workload of operation, and minimize unnecessary human damage.
