How should domestic sewage be treated to meet environmental protection requirements?? What is the price of domestic sewage treatment equipment? What size of equipment should be chosen for small and large amounts of sewage? What is the area occupied by the equipment? What is the cost of treating one ton of sewage? How can we reduce investment in sewage treatment? You can consult. I am Xu Yan, providing free answers and designing wastewater treatment solutions for you.

Currently, A2O is a widely used wastewater treatment process with high COD removal and nitrogen and phosphorus removal efficiency. By investing a relatively small amount of investment (3% to 7%) to transform the structure of the A2O process sewage treatment technology and innovate its process flow, sustainable and efficient COD removal and nitrogen and phosphorus removal effects can be achieved, resulting in effluent that meets Class A standards.

Handling method

The A2O sewage treatment device is characterized by comprising the following equipment: anaerobic tank, anoxic tank, aerobic tank, and secondary sedimentation tank. The anaerobic tank, anoxic tank, aerobic tank, and secondary sedimentation tank are arranged in series. The anaerobic tank has an anaerobic tank and a second anaerobic tank, and the anoxic tank has an anoxic tank and a second anoxic tank. The anaerobic tank and the second anaerobic tank are arranged in parallel, and the anoxic tank and the second anoxic tank are arranged in parallel. The anaerobic tank and the anoxic tank are arranged in series, and the second anaerobic tank and the second anoxic tank are arranged in series.

A2O is characterized by comprising the following steps:

Firstly, the sewage passes through the anaerobic tank and the second anaerobic tank before entering the anoxic tank and the second anoxic tank. After passing through the aerobic tank, it flows into the secondary sedimentation tank, where filtered water and residual sludge are discharged separately. The returned sludge is then subjected to secondary treatment in the anaerobic tank.

After passing through the aerobic tank, a portion of the mixed solution of sewage enters the anoxic tank for secondary treatment.

Domestic sewage treatment equipment refers to the wastewater generated by urban government agencies, schools, and residential areas in daily life, including toilet manure, laundry and bath water, kitchen drainage, as well as drainage from commercial, hospital, and recreational areas. Wastewater generated during human life is one of the main sources of water pollution. Mainly feces and washing wastewater. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, carbohydrates, and lipoproteins; It often contains pathogenic bacteria, viruses, and parasitic eggs; Inorganic salts such as chlorides, sulfates, phosphates, bicarbonates, and sodium, potassium, calcium, magnesium, etc. The overall characteristic is high nitrogen, sulfur, and phosphorus content, and under the action of anaerobic bacteria, it is prone to produce odorous substances.

The buried domestic sewage treatment equipment developed by our company adopts the world's A2O process, which integrates the removal of BOD5, COD, and NH3-N, and is currently the most efficient sewage treatment equipment.

After sewage treatment, the effluent meets the Class A reuse standard in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002) standard.

Equipment features

1. Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than mixed or two-stage series mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, stronger usability for water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and demolding by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

3. 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 the self oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using a manure truck to suction or dehydrate it into a sludge cake for external transportation).

4. The deodorization method of this geographical domestic sewage treatment equipment not only uses conventional high-altitude exhaust, but also includes soil deodorization measures.

5. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.

Usage

1. Capable of treating comprehensive wastewater from living systems and similar organic wastewater;

2. It adopts carbon steel anti-corrosion, stainless steel, glass fiber reinforced plastic structure, with excellent characteristics such as corrosion resistance and aging resistance, and its service life is more than 30 years;

3. The complete set of equipment is simple to construct and easy to operate. All mechanical equipment is automatically controlled, and all devices can be installed on the ground;
