The technical advantages of solar sewage treatment equipment are as follows:
First, easy to use. Can be directly added to the aeration pool, never worry about blocking the system, can never stop water maintenance.
Second, low operating costs. The energy consumption of the equipment mainly comes from the submersible pump and aeration machine in the adjustment tank. The processing process does not require the addition of any flocculant, and because of the intermittent aeration operation, the power consumption is extremely low, which significantly saves the user's operating costs.
Third, the construction time is short and the construction cost is low. Factory modular production, the site can be directly installed in the ground pit on the basis of the construction period is short. No need to make wind room, save civil construction costs. The bottom of the pit only needs to make a concrete foundation platform.
Fourth, beautiful appearance. It is installed in the lawn or bushes of the community and is integrated with the surrounding natural landscape.
Fifth, full automatic control. Unmanned, automatic operation, not only for daily management but also for maintenance, electronic control cabinet equipped with aeration machine and submarine pump fault acoustic light alarm system, trouble point at a glance.
Process, stable and reliable performance, excellent water quality. The main water discharge indicators meet the "pollutant discharge standard for urban sewage treatment plants"(GBl 8918-2002) Level B standard. If deeply processed. It can be used as landscape water and green irrigation water to achieve water reuse.
The internal porosity is high, the specific surface area is huge, the adsorption ability is extremely strong, the microorganism is easy to adhere to. Its appearance is a very fine powdery solid with a specific gravity of about 0.6. Because there are many shell holes on it, special porous structures are formed. The porosity is as high as 90 %, and the absorption ability is extremely strong. The body of the crystal is negatively charged and can adsorb a large number of metal cations and NH4 ions in the water. After adsorbing positive charge ions, its own electricity price loses its balance and is positively charged. This provides the foundation and implementation conditions for the suspension carrier to completely absorb the microorganisms, bacteria, proteins with negative charges, and organic polymer compounds that cause Chromaticity and turbidity.
VIII. Degradation of organic matter, denitrification of phosphorus. Good growth environment and sufficient nutrients enable microorganisms to grow and reproduce on the surface of suspended carriers to form biofilms. The adsorption of polysaccharide extracellular enzymes secreted by microorganisms in biofilms further enhances the energy and effect of adsorption of organic pollutants. Due to the simultaneous action of various microorganisms with different physiological habits, organic pollutants adsorbed on suspended carriers are degraded or mineralized into low-molecular compounds or CO2; Adsorption of NH4 ions in the hole is nitrated by nitrifying bacteria, and then N2 is converted into N2 from the water body for use by specially added aerobic denitrifying bacteria to achieve denitrification. This is a dynamic cycle of both physical and biochemical adsorption-degradation-readsorption-degradation; Phosphorus is absorbed as a nutrient by aerobic microorganisms. After the death of the Biofilm, it is deposited at the bottom of the equipment in the form of biological sludge. Phosphorus is removed through the drainage system.
Nine, easy to fluidize, oxygen utilization rate is high. The particle size of suspended biological carrier particles is at the nanometer level, which is easily miscible with the activated sludge, and the power required for fluidization is low in the currently known suspended fillers. The small particle size of the suspension carrier has achieved a very high contact area and collision probability in the three phases of gas, liquid and solid, and has achieved a high oxygen utilization rate. The energy saving is very obvious.
