Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings, but the content of the present invention is not limited thereto.

[0018] The non-powered sewage treatment device provided by the present invention comprises a hollow shell 3 with a water inlet 13 and a water outlet 4 on it. The hollow shell 3 is an integral glass fiber reinforced plastic columnar closed body, and its cross-sectional shape is circular. In the empty shell 3, from the water inlet 13 to the water outlet 4, an oil-separating corrosion chamber 14, an anaerobic chamber 8, and a sedimentation separation chamber 2 are sequentially arranged, wherein the water inlet 13 communicates with the oil-separating corrosion chamber 14, and the upper part of the oil-separating corrosion chamber 14 An oil separator 12 is provided, which is composed of multiple filter screens, and a hook 121 is provided at its upper end, and the hook 121 is placed in the barb 141 on the top of...

Abstract

The invention provides an unpowered sewage disposal device comprising a hollow housing which is provided with an upper water inlet and an upper water outlet. The invention is characterized in that an oil separation decaying chamber, an anaerobic chamber and a precipitation separation chamber are successively arranged by separation boards from the water inlet to the water outlet in the hollow chamber. Sewage can be conveniently sent to the unpowered sewage disposal device of the invention. Sewage firstly passes through the oil separation decaying chamber, the sewage decays in short time, so that organic pollutants in the sewage can change into hemicolloid substance, and the hemicolloid substance enters the anaerobic chamber via a water pipe; under the oxygen-poor condition, anaerobic bacteria can be quickly cultivated and propagated by fillers in the anaerobic chamber, so that organic pollutants in large quantity are decomposed into inorganic substances, and treated sewage is led into a precipitation chamber via the water pipe; organic residues in water can be further purified by a purifier so as to finish treatment to COD, BOD, SS and total phosphorus in the sewage, and clear water reaching the standard automatically flows out of the water outlet.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a non-powered sewage treatment device, which belongs to the technical field of sewage treatment. Background technique [0002] In order to protect the fresh water resources that human beings depend on for survival, and prevent limited lakes and rivers from being polluted by humans, governments at all levels are stepping up efforts to treat industrial sewage and urban domestic sewage, and have achieved satisfactory results. Since our country is an agricultural country, most of the people are agricultural population, and the area is wide, therefore, the treatment of rural domestic sewage cannot be ignored. However, the current sewage treatment system is not applicable in rural areas, because in the vast rural areas, single households or courtyards are used as units, and it is difficult to use the existing sewage treatment system for centralized treatment. Therefore, the existing techno...
