Novel multifunctional oxidation pond for rural domestic wastewater treatment

Abstract

The invention discloses a novel multifunctional oxidation pond for rural domestic wastewater treatment. The novel multifunctional oxidation pond is provided with an oxidation pond body; a water inlet is formed in the left side of the oxidation pond body; an overflow opening and a flow gathering groove are formed in the right side of the oxidation pond body; a medium device is arranged at the upper part in the oxidation pond body; the lower part of the medium device is provided with a floating ball layer; the lower part of the floating ball layer is provided with a water outlet; the water outlet is connected with the flow gathering groove; the medium device is provided with a red brick layer and a medium layer; a stainless steel net is arranged between the red brick layer and the medium layer; a bamboo weaving net is arranged between the medium layer and the floating ball layer; the red brick layer is positioned at the upper part of the medium layer. The novel multifunctional oxidation pond has the advantages that the problem of environment pollution caused by rural domestic waste water is solved; the potential safety hazards in rural water source places is avoided; the crisis of gradual shortage of fresh water resources is relieved; thus, the environment safety of rural society development is ensured.

Description

technical field [0001] The invention belongs to the field of domestic sewage treatment, and in particular relates to a novel multifunctional oxidation pond for rural domestic sewage treatment. Background technique [0002] Environmental pollution caused by domestic sewage in rural areas is not only a potential safety hazard in rural water sources, but also exacerbates the crisis of fresh water resources, thus endangering the sustainable development of rural society. Different from urban water use, rural water is generally used comprehensively by river water, well water and tap water, and generally the amount of domestic sewage in rural areas is relatively small, the sewage discharge is uneven, the water volume changes significantly, the instantaneous change is large, and the daily variation coefficient is small . The water quality of most rural domestic sewage is not much different, with good biochemical properties and a certain amount of nitrogen, phosphorus, and pathogeni...
