Unpowered domestic sewage treatment device for individual investors

Abstract

The invention discloses an unpowered domestic sewage treatment device for individual investors. The unpowered domestic sewage treatment device for the individual investors comprises a sewage treatmentbox I, a sewage treatment box II, a sewage treatment box III and a recycling box; a purification area containing anaerobes is arranged at the bottom end of the sewage treatment box I; a sewage pipeline comprises a sewage pipeline I and a sewage pipeline II which is arranged in the sewage pipeline I in a sleeving way; a carrier plate for aerobes to attach to is arranged on the inner wall, positioned at the bottom end of the sewage pipeline II, of the sewage pipeline I along the axial direction; gas inlet holes are formed in the side wall, positioned above a water outlet hole, of the sewage pipeline I at equal interval; a medicine box for accommodating an inorganic phosphorus remover is arranged at the inner top end of the sewage treatment box II; and an unpowered administration mechanism is arranged in the sewage treatment box II. The domestic sewage is purified step by step by a biological method and a chemical method, vegetable leaves are filtered out while purification is conducted,the vegetable leaves are recycled to serve as organic fertilizer to change waste into treasures, and the whole device is not provided with power equipment, so that the domestic sewage treatment costis reduced.

Description

technical field [0001] The invention relates to the technical field of domestic pollution, in particular to a non-powered domestic sewage treatment device for retail households. Background technique [0002] Domestic sewage mainly includes sewage produced by washing vegetables, dishwashing water and laundry water, while laundry water and dishwashing water contain a large amount of inorganic phosphorus, while vegetable washing water contains vegetable leaves, and untreated domestic sewage passes through point sources And non-point sources are discharged into natural water bodies, bringing various pollutants into rivers, leading to many ecological and environmental problems such as serious eutrophication of water bodies, cyanobacteria and aquatic plants. [0003] In cities and rural areas near cities, due to the relatively developed sewage pipe network, the domestic sewage in these places is generally received by the sewage pipe network and then enters the urban sewage treatme...

[0002] Domestic sewage mainly includes sewage produced by washing vegetables, dishwashing water and laundry water, while laundry water and dishwashing water contain a large amount of inorganic phosphorus, while vegetable washing water contains vegetable leaves, and untreated domestic sewage passes through point sources And non-point sources are discharged into natural water bodies, bringing various pollutants into rivers, resulting in many ecological and environmental problems such as serious eutrophication of water bodies, cyanobacteria and aquatic plants.

[0003] In cities and rural areas near cities, due to the relatively developed sewage pipe network, the domestic sewage in these places is generally received by the sewage pipe network and then enters the urban sewage treatment plant for centralized treatment. Sewage pipe network, and it requires a very large investment cost

And because the residents in these areas are often scattered, the cost of sewage collection and management is very high, so it is impossible to establish centralized small sewage treatment facilities
