Rural sewage treatment station control method

Abstract

The invention discloses a rural sewage treatment station control method. A central intelligent control unit locates a sewage station address through a GPS module, and obtains local meteorological datathrough a 4G module and a rainfall monitoring sensor; then the liquid levels of an adjusting tank and an MBR membrane tank are read, the flow rate is calculated according to the liquid levels, the meteorological data and historical water volume data in the morning, at noon and at night, and the running time of a water inlet pump and a fan are adjusted, and therefore, the sludge concentration andthe aeration time are intelligently controlled; whether a sludge return pump is started or not is determined according to the concentration of the sludge in the MBR membrane tank; and whether a cleanwater pump is started or not is determined according to the liquid level in the MBR membrane tank. According to the invention, the GPS module is used for positioning an area to which the sewage station belongs, the 4G module is used for capturing latest weather information on a meteorological website, and the rainfall monitoring sensor and the liquid level detection sensor are used for intelligently predicting rainfall information of several hours and even several days later, so that a control strategy is automatically adjusted, and the activity and concentration of sludge are ensured.

Description

technical field [0001] The invention relates to the technical field of rural sewage treatment, in particular to a control method for rural sewage treatment stations. Background technique [0002] With the acceleration of urbanization and industrialization in our country, the discharge of waste water in the country has also increased year by year, resulting in continuous deterioration of natural water bodies, and the situation of water resource pollution is still very severe. In order to prevent and control water pollution and alleviate the shortage of water resources, the state has vigorously implemented energy-saving and emission-reduction policies in recent years. The central government and local governments at all levels have continuously increased investment in the construction of urban sewage treatment facilities. Standard system, urban sewage treatment industry is developing rapidly. However, the development of sewage treatment facilities in China is still unbalanced ...

Problems solved by technology

[0005] 2. Large regional differences: The climate and environment in the north and south, east and west of my country are different, and the applicable process and design parameters for rural sewage treatment are also very different

[0006] 3. Large changes in water quantity and quality: At different times of the day, the water quality and quantity change greatly and are relatively concentrated; especially during the concentrated cooking time in the morning, middle and evening, the sewage volume reaches a peak, which is 2 to 3 times the usual sewage discharge volume; In addition, the rural drainage system is very imperfect and has not been properly planned. The rain and sewage are mixed. Affected by the rainy season, the coefficient of water volume variation is large.

On the other hand, the existing sewage station did not adjust its control strategy in time according to the rain and snow weather
