Lakes refer to slowly flowing bodies of water formed by water accumulation in depressions on land. The lake water contains two types of impurities, the first type of impurities is suspended matters, the particles are maximum, and the diameter of the particles is about 1 multiplied by 10 -4 Above mm, the impurities exist in unstable state in water and are easy to separate from the water body; the second type of impurity is a colloid, typically having a particle diameter of 1X 10 -6 mm-1×10 -4 Between mm, is an aggregate of many molecules and ions. Compared with well water and spring water, the lake water has more suspended matters and colloids.
The existing filter comprises a water inlet tank, a U-shaped water inlet pipe, a filter chamber, a water collecting chamber, a flushing water tank, a water outlet pipe, a siphon ascending pipe, a siphon descending pipe, a siphon auxiliary pipe, a siphon breaking pipe and a water sealing tank, water to be treated sequentially enters the filter chamber through the water inlet tank and the U-shaped water inlet pipe, then enters the water collecting chamber after being filtered through a filter layer, water in the water collecting chamber enters the flushing water tank through the water collecting pipe, and the water in the flushing water tank is filtered water and is discharged from the water outlet pipe. The filter system has an automatic back flushing function, i.e. the filter layer can be automatically and periodically back flushed to clean the filter layer. The water for back flushing the filter layer comes from the water in the flushing water tank, and the water consumption for back flushing each time is the water which can be contained in the flushing water tank from the lower end of the siphon breaking pipe to the top end of the water outlet pipe.
