Embodiment Construction

[0020] The technical scheme provided by the present invention is: a method for improving rural sewage treatment, the steps of which are:

[0021] (1). First, the rural sewage is introduced into the grid well for impurity removal. The grid well is composed of a square grid with a side length of 2-3 cm. The grid well is used to filter out floating objects and large scales in the sewage. Diameter debris

[0022] (2) Next, the water from the grid well enters the first sedimentation tank, and the first sedimentation tank preliminarily statically settles the inflowing sewage, so that the impurities with a larger specific gravity in the sewage will settle to the bottom of the first sedimentation tank. And regularly clean the sludge at the bottom of the first sedimentation tank;

[0023] (3) Next, the preliminarily settled sewage overflowing from the top of the first sedimentation tank enters the first purification room, and puts lime powder into the first purification room. The amount of l...

Abstract

The invention discloses a method for improving rural sewage treatment. The method for improving rural sewage treatment is simple and scientific in process, and low-cost and high-efficiency filtrationand purification of rural sewage are finally realized through primary filtration, precipitation, aeration, secondary filtration and secondary precipitation and filtration of a biological tank on the rural sewage. In conclusion, the method for improving rural sewage treatment is stable and reliable, and related sewage treatment equipment is small in occupied area, easy to construct, simple and convenient to maintain, low in capital construction investment and low in operation cost; the damage to the ecological environment and the generation of black and odorous water are avoided, the rural sewage treatment effect is stable, the operation cost is relatively low, the rural sewage is comprehensively utilized to the maximum extent through a reasonable sewage treatment method, and the method issuitable for popularization and application.

Description

Technical field [0001] The invention belongs to the technical field of environmental treatment, and specifically relates to a method for improving rural sewage treatment. Background technique [0002] With the continuous development of the rural economy and the continuous improvement of people's requirements for the quality of rural living environment, the construction of new rural areas promoted by governments at all levels has greatly improved the living environment of farmers. However, the contradiction between the relatively lagging infrastructure construction in rural areas and the scattered point source water pollution in rural areas has become increasingly prominent, and it is urgent to solve the problem of rural water environmental pollution. [0003] The selection and use of rural sewage treatment technology is restricted by various factors such as regional economic conditions, climate conditions, and village land resources. The development of rural sewage treatment techno...
