Quotation for solar powered sewage treatment equipment

Quotation for solar powered sewage treatment equipmentIt uses solar photovoltaic panels to convert solar energy into electrical energy for treating sewage. After the battery is fully charged, even if it rains continuously for 7 days, it can ensure the normal operation of sewage treatment. After multiple procedures such as pipeline collection of sewage, anaerobic biological treatment, contact oxidation, sedimentation, and standard discharge, the originally turbid sewage becomes very clear.

1. Solar photovoltaic cells. Using monocrystalline silicon or polycrystalline silicon cells, the high output power of the cell should not be less than 400W, and the power error requirement should be within ± 3%; The photoelectric conversion rate of the battery is greater than 16%; The battery output power is greater than 90% within 10 years and greater than 80% within 25 years; Under normal use, the product's lifespan is required to be greater than 25 years.

2. Battery. Equipment batteries are required to be equipped with solar energy batteries; The battery capacity shall not be less than 800AH and shall be able to meet the system's operating requirements for 7 consecutive rainy days; The service life of the battery shall not be less than 6 years.

3. Aeration system. The required aeration rate is not less than 5.0m3 per hour, and the daily aeration rate is not less than 100m3; the aeration pressure can meet the working requirements at a depth of 2.0 meters underwater.

4. Equipment control system. It has protection function for overcharging and overdischarging of batteries, and thermal compensation function; It has the function of preventing backflow discharge for photovoltaic panels; It has protection and automatic restart function for the inverter; It has protection and intelligent distribution functions for the load.

Quotation for solar powered sewage treatment equipmentThe main process flow is as follows:

1. The solar powered sewage treatment equipment removes some suspended solids, as well as organic and inorganic substances suspended in large particles, through a filtering grid

2. After filtration, the sewage flows into the anaerobic tank, where anaerobic microorganisms are used to degrade the organic matter in the sewage, oxidizing the organic matter of large molecule complex chains into small molecule single chain organic matter.

3. Wastewater and phosphorus containing sludge returning from the sedimentation tank release phosphorus in an anaerobic state, which can be absorbed in a large amount in a solar aerobic tank for phosphorus removal through sludge discharge. Part of the ammonia nitrogen in the sewage is converted into NH3-N in the solar primary aerobic tank. After the self flowing sewage enters the anoxic tank, denitrifying bacteria use the organic matter in the sewage as a carbon source to reduce the large amount of NO3-N and NO2-N brought into the first aerobic tank to N2 and release it into the air, thereby removing ammonia nitrogen.

4. After the anoxic tank, the secondary aerobic tank is used to remove pollutants such as CODcr and SS.

5. Elastic packing is installed in the contact oxidation tank, and a microporous aerator is installed to increase dissolved oxygen concentration through aeration by a blower. Due to the BOD sludge load used in this project being less than 0.1kgBOD/kg (MLSS) · d, the system maintains a high sludge concentration, resulting in very little sludge production in this project. The secondary sedimentation tank is equipped with a sludge discharge device, which discharges sludge at regular intervals and treats it as fertilizer nearby.
