Product details
1、 Main function
1. Wastewater treatment (the process of purifying wastewater to meet the water quality requirements for drainage or reuse in a certain body of water. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.)
2. Reclaimed water reuse (Reclaimed water reuse technology refers to the centralized treatment of household waste water (such as bathing, washing, laundry, kitchen, and toilet) in residential areas, which is reused to a certain standard for greening irrigation, vehicle washing, road washing, household toilet washing, etc., in order to achieve the goal of water conservation.)
3. Improve the water quality of downstream discharge water bodies and transfer them to meet the standards of rivers.
4. The ecological water replenishment function of rivers and lakes, in addition to meeting the political task of reducing COD and ammonia nitrogen emissions in local national energy conservation and emission reduction, is an important project for the performance assessment of local government leaders and must meet the standards.
2、 Equipment advantages
1. Strong ability to withstand impact loads. The average residence time of contact oxidation method is more than 6 hours;
2. It has the ability to remove nitrogen and phosphorus, and can achieve the ability to treat industrial wastewater, domestic sewage, and urban sewage by adjusting the structure of the equipment;
3. The fillers in the contact oxidation tank are mostly composite soft fillers, which are lightweight, high-strength, physically and chemically stable, have a large specific surface area, strong biofilm adhesion ability, and high contact efficiency between sewage and biofilm;
4. An aerator is used in the contact oxidation tank for air blowing aeration, causing the fiber bundles to continuously float and aerate evenly, resulting in mature microbial growth and possessing the characteristics of activated sludge process;
5. Stable effluent quality, low sludge production and easy treatment;
6. Submersible pumps can be installed in equipment to reduce project investment;
7. The equipment can be installed on the ground or buried underground. When buried underground, the upper cover can be used for greening, resulting in a smaller factory area and fewer ground structures;
8. Easy to achieve automatic control and simple management operation.
9. The device can be connected to a car to make a mobile integrated rural sewage treatment equipment.
3、 Working principle
Small rural domestic sewage treatment equipmentThe working principle of the A-level tank is that due to the high concentration of organic matter in the sewage, microorganisms are in a state of hypoxia. At this time, microorganisms are facultative microorganisms. Therefore, the A-level tank not only has a certain organic matter removal function, but also reduces the organic load of the subsequent aerobic tank. The organic matter concentration decreases, but there is still a certain amount of organic matter and high NH3-N present. In order to further oxidize and decompose organic matter, and ensure smooth nitrification under carbonization, an aerobic biological contact oxidation tank with low organic load is set up at level O. There are mainly aerobic microorganisms and self oxidizing bacteria in the O-level pool. Aerobic microorganisms decompose organic matter into CO2 and H2O; Autotrophic bacteria use inorganic carbon produced by the decomposition of organic matter or CO2 in the air as a nutrient source to convert NH3-N in wastewater into NO-2-N and NO-3-N. The effluent from the O-grade tank flows back to the A-level tank, providing electron acceptors for the A-level tank, and ultimately eliminating nitrogen pollution through denitrification.
