Abstract

The invention discloses an eco-biofilter apparatus and its sewage treatment method, and belongs to the field of biological sewage treatment. The eco-biofilter apparatus comprises a water tank and an eco-biofilter housing. A composite packing zone in the eco-biofilter housing is filled with attapulgite clay ceramsite and a bamboo wool packing. Mass ratio of the attapulgite clay ceramsite to the bamboo wool packing is (1-3):1. Crops are planted on the composite packing zone. The attapulgite clay ceramsite is prepared from, by weight, 50-60% of attapulgite clay, 20-25% of flour and 15-30% of iron filings. Two packings are used to form the composite packing, thus being beneficial to form a more complex ecological system and a more stable ecological chain. The eco-biofilter apparatus is applicable to a single family or several neighbor families. Treatment effect is guaranteed under the condition of low temperature. By combining respective advantages of a biological aerated filter, crops and the composite packing, the purification effect is good, and multiple pollutants can be removed simultaneously. In addition, particle size of the composite packing is large, thus avoiding the back-wash process.

Description

technical field [0001] The invention belongs to the field of sewage biological treatment, and more specifically relates to an ecological filter device and a method for treating sewage. Background technique [0002] With the development of the rural economy and the need for environmental protection around the countryside, the amount of rural domestic sewage is increasing year by year, and random discharge leads to breeding of mosquitoes and flies, cross-flow of sewage, and foul smell; rural domestic sewage treatment is also an important aspect of rural ecological environment protection. It is of great value to prevent water pollution and eutrophication in rural areas. [0003] At the end of the 20th century, the domestic sewage generated by each household was discharged randomly, and the rural areas were scattered, and the self-purification ability of a large amount of land, ditches and grasslands in the residential area was sufficient to purify rural domestic sewage; and the...
