Abstract
The invention relates to the field of sewage treatment and particularly relates to a treatment method for rural domestic sewage. The method comprises the following steps of (1) introducing sewage into a water channel by using a water pump and carrying out coarse filtration on the sewage to remove large particle sundries; (2) infiltrating the sewage into a container B through the water channel in the step (1) and carrying out fine filtration on small molecular impurities in water; (3) introducing the sewage filtered through the container B into a container C, vacuumizing the container C by using an air pump or filling carbon dioxide; (4) introducing the sewage in the container C into a container D, continuously filling the sewage with fresh air by using the air pump; (5) exporting the sewage in the container D for laboratory analysis, supplementing elements and then introducing the sewage into a soilless culture container; and (6) introducing the sewage in the soilless culture container into an eichhornia crassipes culture pond. The treatment method is low in equipment cost and high in sewage treatment capacity; and the sewage can be directly discharged after being treated, so that the treatment method has very high practicability.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a treatment method for rural domestic sewage. Background technique [0002] Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life. Most of them are non-toxic inorganic salts. Domestic sewage contains a lot of nitrogen, phosphorus, sulfur, and many pathogenic bacteria. The sewage produced in the process of human life is one of the main sources of pollution of water bodies, mainly feces and washing sewage. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fatty protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, Potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus content, and under the action of anaerobic bacteri...
