Sewage treatment system and treatment method for northern rural areas, construction method and control system

Abstract

The invention relates to a sewage treatment system and a treatment method for a northern rural areas, a construction method and a control system. The construction method comprises the following stepsof constructing a grate pool foundation pit, a regulating pool foundation pit, a biologic treatment pool foundation pit, a constructed wetland foundation pit and a sterilization pool foundation pit that are communicated in sequence; putting a grate in the grate pool foundation pit, adding a weak base solution in the regulating pool foundation pit, putting a biologic treatment device in the biologic treatment pool foundation pit, filling the constructed wetland foundation pit with a matrix, so as to form constructed wetland, growing plants ion the constructed wetland, and pouring sterilizationliquid into the sterilization pool foundation pit; and growing plants in the constructed wetland, covering the constructed wetland with a greenhouse, and installing a solar battery outside the greenhouse, so as to provide heat to the greenhouse. Currently, in the northern rural area, sewage treatment in winter faces many problems such as poor treatment effect, high system running energy consumption, poor biological landscape effect, and complex management and operation. The sewage treatment system and the construction method thereof and the control system solve the problems.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system, a treatment method, a construction method and a control system used in northern rural areas. Background technique [0002] For a long time, due to the lag in the construction of rural environmental protection infrastructure, a large amount of untreated rural domestic sewage has been discharged randomly across the country. The reason has aroused great concern from the society. [0003] Rural sewage treatment has the characteristics of small water volume, large time fluctuations, scattered distribution, and difficult management. In view of the above characteristics, it is difficult to obtain the ideal treatment effect by conventional sewage treatment methods. The biofilm method is used to treat rural domestic sewage, which has the advantages of high degradation efficiency of organic pollutants and wide application. However, the method of single biofilm t...

Problems solved by technology

[0006] In view of the above problems, the present invention is proposed in order to provide a sewage treatment system, treatment method, construction method, and control system for northern rural areas that overcome the above problems or at least partially solve the above problems, and adopt an ecological combined sewage treatment method to realize The effective control of rural sewage solves the problems of poor winter sewage treatment in northern rural areas, high energy consumption in system operation, poor ecological landscape effect, and complicated management operations.
