gls tanks supplier from china

gls tanks are becoming more and more popular because of their environmental protection and low cost.we are a gls tanks supplier from china.today we introduce purification of biogas from domestic sewage.

The technology of domestic sewage purification and biogas is suitable for towns with no economic capability or planning to build centralized sewage treatment plants in the near future. The technology is also applicable to sewage disposal in such places as office buildings, hotels, schools, health homes, residential quarters and public sides, which have been built in the concentrated treatment plant of urban sewage.

Characteristics of biogas technology for sewage purification:

1. small, scattered and scale of construction can be tailored to local conditions and investment.In the construction of centralized sewage treatment plants in small and medium-sized cities and towns, because of the scattered distribution of office buildings, hotels, schools, health centers and residential areas, the investment of the pipe network is very large. Sewage purification by domestic sewage is used to treat domestic sewage. According to the scope and discharge of sewage discharge, it is possible to disperse and disperse the pool according to local conditions and disperse the treatment. It is not necessary to lay the centralized pipe network and save investment of gls tanks supplier from china.

No land occupation, domestic sewage purification biogas digester is an underground construction device, using reinforced concrete structure, does not occupy the land.

3.No power operation, no energy consumption, convenient management and low operating cost. The domestic sewage purification biogas technology is degraded by multistage self flow and grading digestion. It does not require power forced flow or aeration degradation. It does not need special management. Usually, it needs to be cleaned once in 2-5 years, which is more convenient than ordinary septic tank management and low operating cost.

4. the treatment effect is good, and the biogas can be recovered. By anaerobic digestion and aerobic filtration, the removal rate of COer and BOD5 can reach about 90%, and all kinds of parasite eggs are killed, which not only make the effluent meet the first and two levels of the national sewage discharge standard, but also can be recycled for the use of water, and it can also be recycled. The amount of biogas is used for cooking, boiling water or lighting.

Benefits of gls tanks supplier from china

The sewage of the farm is discharged into the regulating pool from the drain through the grille, and the livestock manure is transported to the regulating pool artificially, and the sewage is stirred into the metering tank with gls tanks supplier from china the sewage, and then the anaerobic fermentation is carried out in the anaerobic reactor by the sludge pump. The "energy ecological" biogas project can be fermented at room temperature or medium temperature or near medium temperature.

In order to achieve medium temperature fermentation at about 35 C, the boiler steam or the waste heat from the surrounding enterprises are heated in the metering tank, and the steam or residual heat into the metering tank is automatically adjusted by the temperature controller. In addition to heating with steam or waste heat, it is also possible to use partially returned biogas for heating. The biogas produced by the anaerobic reactor is then dehydrated and desulfurized and purified to enter the gas storage tank for production or living energy consumption. The manure is regularly discharged as organic fertilizer for farmland, orchard, tea garden and bamboo forest. Biogas slurry can not only be used as a liquid organic fertilizer, but also as a bait for fish farming. The "energy ecotype" biogas project requires that there are enough farmland, orchard, mountain forest and fish pond around it to eliminate the biogas liquid and methane produced by anaerobic fermentation. For example, two pollution will be produced if the elimination is incomplete.

The effluent from the aquaculture field is first removed through the grille and then flowing into the regulating pool through the pipeline. The water pump in the regulating pool is pumped into the centrifuge for solid-liquid separation, and the fecal slag with water content of about 30% is processed into organic manure, and the separated low concentration sewage flows into the sedimentation tank.

The supernatant of the settling tank is self pumped into the sump, and the water distributor of the anaerobic reactor is uniformly injected into the anaerobic reactor through a water extraction pump. The waste water in the anaerobic reactor is digested and decomposed by methanogens, and the biogas generated by the separation of gas and water, and after desulfurization and purification, enters the gas storage tank. After the oxygen is digested, the sewage will flow into the post-processing system automatically, then be treated with aerobic treatment, then discharge to standard or reclaimed water. The "energy conservation and environmental protection" biogas project requires the final effluent to reach certain standards and discharge into the natural water body.
