Sewage treatment device

Abstract

The invention discloses a sewage treatment device which comprises a sewage storage box, a sediment box, a first filtering box, a second filtering box, a disinfecting tank and a clean water tank, wherein the sewage storage box is connected with the sediment box through a water outlet pipe; the sediment box is connected with the first filtering box through a guide pipe; the first filtering box, the second filtering box, the disinfecting tank and the clean water tank are connected with each other through the water outlet pipe; a separating plate is arranged at the top of the sewage storage box; a stirrer is mounted at the bottom end of the sediment box; a drug-adding device is arranged at the upper end of the sediment box; a water pump is arranged on the guide pipe; a first filtering plate and a second filtering plate are arranged on the first filtering box; a disinfecting gas generator is arranged at the upper end of the disinfecting tank. According to the sewage treatment device, the sediment box, the first filtering box, the second filtering box and the disinfecting gas generator are used for performing sediment and repeated filtering treatment, so that the sewage is sufficiently purified; the structure is simple; the cost for treating the sewage is low; the sewage treatment device is fit for various places.

Description

technical field [0001] The invention relates to a sewage treatment device, which belongs to the technical field of waste water treatment equipment. Background technique [0002] Domestic wastewater refers to the washing water excreted in people's daily life. With the rapid economic development, people's water consumption in various aspects is increasing. In fact, only a small part of the wastewater has been treated, and most of it is directly discharged into the environment without treatment. In addition to rivers and other polluted environments, small cities are even more serious. [0003] In addition, recycling domestic wastewater after collection and treatment has become a way to save water resources. However, the recycling and utilization of domestic wastewater is still relatively small at present, mainly because the existing sewage treatment devices are too large in size, the equipment price is high, and the operating cost is also high, which is not suitable for widesp...
