Embodiment Construction

[0018] A domestic sewage purification process, such as figure 2 As shown, the process includes specific steps in the following sequence: pass domestic sewage through the debris removal tank to intercept domestic debris, control the flow rate of sewage at 0.1-0.3 cubic meters per hour, and control the retention time at 30-50min; the intercepted sewage Enter the anaerobic filter bed pool for anaerobic fermentation for 12-24 hours, remove deactivated organic matter after fermentation, control the fermentation temperature at 35-55°C, and control the pH at 5.5-6.5; the sewage after anaerobic fermentation enters the filled flow pool for exposure Gas fermentation, the sewage after aeration and fermentation enters the sedimentation tank for sedimentation for 5-8 hours, the supernatant is sterilized and discharged from the chlorine disinfection tank for recycling, and the lower part of the sediment is in the state of aeration and agitation, and the water pump returns to the sundries re...

Abstract

The invention discloses a domestic wastewater purifying treatment technology. The technology includes the following specific steps that domestic wastewater passes through an impurity removing tank, and domestic impurities are intercepted; the wastewater obtained after interception is conducted enters an anaerobic filter bed tank to be subjected to anaerobic fermentation; the wastewater obtained after anaerobic fermentation enters a packing flowing tank to be subjected to aeration fermentation; the wastewater obtained after aeration fermentation enters a settling pond to be settled, after settling is conducted, upper clean liquid is disinfected through a disinfecting tank to be discharged and recycled, and the lower sediment part flows back to the impurity removing tank through a water pump in an aeration stirring state to be circularly treated. The technology is simple and suitable for miniaturized and domestic use. The domestic waste water is purified through the impurity removing tank, the anaerobic filter bed tank, the packing flowing tank and the settling tank in sequence, miniaturization and domestication of domestic wastewater treatment are achieved, the treatment efficiency of the domestic wastewater is improved, the removing efficiency of BOD, SS and ammonia nitrogen is high, and the burden of large-size concentrated wastewater treatment of the domestic wastewater is reduced.

Description

technical field [0001] The invention relates to a sewage treatment process, in particular to a domestic sewage purification treatment process. Background technique [0002] The existing domestic sewage treatment process can be divided into primary, secondary, and tertiary treatment processes according to the degree of treatment. The primary treatment process is to set up a fence at the entrance of the sewage treatment facility; the secondary treatment process mainly removes colloidal and soluble organic substances in the sewage, usually using biological treatment. Primary and secondary treatment processes are conventional treatment methods. The tertiary treatment process is used to further treat difficult-to-degrade organic substances, phosphorus and nitrogen and other soluble inorganic substances that can lead to oxidative enrichment of water after the primary and secondary treatment. [0003] Sewage produced in the process of human life is one of the main sources of wate...
