Problems solved by technology

With the development of my country's rural social economy, rural residents are scattered, and the economic conditions are quite different. The construction of sewage pipe network and sewage treatment facilities is relatively lagging behind. The water quality and quantity of rural domestic sewage are also different. At present, these domestic sewage are usually concentrated Discharged to the sewage treatment tank for treatment, mainly including anaerobic treatment, nitrification treatment, sedimentation, aeration treatment, etc., the existing sewage treatment methods have the following disadvantages: (1) the suspended solids in the effluent are unstable and easy to exceed the standard; (2) the effluent There are no disinfection facilities, and the germs exceed the standard; (3) High energy consumption

Embodiment 1

[0023] A kind of rural sewage treatment method, this method comprises the following steps:

[0024] Step 1. Pass the rural domestic sewage into the grid well through the laid pipeline, and remove the large debris in the sewage;

[0025] Step 2, passing the sewage treated in step 1 into the regulating tank to regulate the water quality and quantity;

[0026] Step 3. The sewage treated in step 2 is quantitatively transported to the anaerobic pool through the water pump for anaerobic treatment. After the anaerobic treatment, the sewage is passed into the anoxic pool for treatment, and the sewage after the anoxic treatment is passed into the aerobic pool. , the aerobic tank is aerated through the fan, the sewage after the aerobic treatment is passed into the anoxic tank through the pipeline for secondary treatment, and then the sewage after the secondary anoxic treatment is passed into the aerobic tank for secondary treatment Oxygen treatment;

[0027] Step 4, passing the sewage...

Abstract

The invention relates to a method for treating rural sewage, and relates to the field of sewage treatment. The method comprises the following steps of step I, introducing rural sanitary sewage into agrating well through a laid pipeline, and removing large piece sundries in the sewage; step II, introducing the sewage treated in the step I into a regulating tank, and regulating water quality and water quantity; step III, quantitatively conveying the sewage treated in the step II to an anaerobic tank, an anoxic tank and an aerobic tank in sequence through a water pump to carry out treatment; step IV, introducing the sewage treated in the step III into a sedimentation tank, adding a sewage treating agent into the sedimentation tank, and carrying out solid-liquid separation; step V, introducing the sewage treated in the step IV into a bioaeration filter tank to carry out filtration, and removing suspended matters in water; step VI, carrying out ultraviolet disinfection on the sewage treated in the step V. The method for treating the sewage, which is provided by the invention, cooperates with the sewage treating agent used in the method, and can be used for realizing thoroughly, quicklyand efficiently controlling the sewage, and the quality of controlled yielding water is stable.

Description

Technical field: [0001] The invention relates to the field of sewage treatment, in particular to a rural sewage treatment method. Background technique: [0002] Since the reform and opening up, my country's industrialization level has been continuously improved. While we are enjoying the achievements of rapid GDP growth, environmental pollution hinders sustainable economic development has become a problem that cannot be ignored. The problem of domestic sewage in rural areas is not only related to the health of farmers, but also related to the improvement of rural ecological environment and the harmony of rural society. Water environment protection is the focus of current environmental protection work, and rural domestic sewage treatment is an important part of water pollution prevention and control. With the development of my country's rural social economy, rural residents are scattered, and the economic conditions are quite different. The construction of sewage pipe networ...
