Abstract

The invention relates to the field of sewage treatment, and particularly discloses a low-cost sewage treatment method. The low-cost sewage treatment method comprises the steps: 1) pretreating; 2) carrying out coagulating sedimentation treatment by using a coagulant; 3) carrying out coagulation post-treatment; 3-1) sludge treatment; and 3-2) carrying out hydrolysis acidification treatment; and 4) carrying out SBR treatment. The coagulant comprises the following components: a coagulant, a larch tannin extract, chitosan, water hyacinth root powder and a coagulant aid according to the mass ratio of 1:(0.8-1):(0.5-0.7):(0.4-0.6):(0.05-0.07). The sewage treatment method with low cost can be used for domestic sewage, and has the advantages that the treatment capacity is high, and water meeting the national first-grade A standard is obtained.

Description

technical field [0001] This application relates to the field of sewage treatment, more specifically, it relates to a low-cost sewage treatment method. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) Eggs and intestinal infection virus, etc.). The organic matter in domestic sewage is extremely unstable, easy to rot and produce stench, and bacteria and pathogens multiply with the organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, life Sewage must be treated before discharge. [0003] At present, the SBR method is used to treat domestic sewage. The main feature is the orderly and intermittent operation in operation. The core of SBR technology is the SBR reaction tank, whic...
