The wastewater produced in the process of human life is one of the main sources of water pollution. Domestic sewage contains a large number of organic matter, such as cellulose, starch, sugar and fat protein. It also contains pathogenic bacteria, viruses and parasites. Chloride, sulfate, phosphate, sodium bicarbonate, sodium, potassium, calcium, magnesium, etc.. It is characterized by high content of nitrogen, sulfur and phosphorus, which is easy to produce malodorous substances under anaerobic bacteria. Therefore, we must go through the sewage treatment equipment can be discharged after treatment, and now we come together to understand the characteristics of domestic sewage treatment technology?
1, buried in the ground below the surface of the equipment can be used as a green or other land, do not need to build houses and heating, insulation.
2. The biological contact oxidation process of the two and the third stage adopts the biological contact oxidation with push flow, and the treatment effect is better than that of the complete mixed type or the two stage series complete mixed biological contact oxidation tank.
3, biochemical pool by biological contact oxidation, the filler volume load is relatively low in microbial self oxidation stage, less sludge production, only three months (90 days) more than a row of mud (with fecal suction or dehydrated sludge cake Sinotrans).
4, the sewage treatment equipment in addition to the use of conventional way of high altitude air exhaust, another with soil deodorization measures.
5, the entire equipment processing system is equipped with automatic electrical control system and equipment fault alarm system, safe and reliable operation, usually do not need special management, just in time to the equipment maintenance and maintenance.
