High-turbidity sewage filtration equipment

Abstract

The invention discloses high-turbidity sewage filtration equipment, which comprises a cylinder. The lower end of the cylinder is provided with a supporting board; a water generation chamber is formed between a cylinder base and the supporting board and provided with a water outlet; a water inlet is formed on the cylinder; a plurality of hollow filter elements are arranged on the supporting board; the supporting board is provided with water discharge holes through which hollow parts of the filter elements are communicated with the water generation chamber; a hollow filter element supporting tube is arranged in each filter element; the side of the filter element supporting tube is provided with a plurality of permeable holes of the filter element; and a filter element cap is arranged on each filter element. The high-turbidity sewage filtration equipment has the advantage that: when a large number of suspended substances are attached to the surface of each filter element and the filter capacity of the filter elements is weakened or lost, the filter element supporting tubes can prevent the filter elements can be prevented from being deformed or burst caused by high inside and outside pressure difference.

Description

technical field [0001] The invention relates to a sewage filtering device, in particular to a high turbidity sewage filtering equipment. Background technique [0002] There is a high turbidity sewage filtration equipment such as figure 1 As shown, it includes a cylinder, which is equipped with dozens to hundreds of hollow filter elements. After the sewage entering the cylinder is filtered by the filter elements, a large amount of suspended particles in the sewage will be retained and the turbidity of the sewage will be reduced. A support plate for fixing the filter element is arranged at the lower end of the cylinder, and a water outlet hole is arranged on the support plate for the water filtered by the filter element to discharge. In order to fix the upper ends of a large number of filter elements, an upper cover plate is arranged above the filter element, and then the upper cover plate is fixed on the filter element with a filter element pressing plate. This kind of trea...

AI Technical Summary

Problems solved by technology

This kind of treatment equipment has the following disadvantages: the hollow filter element is made of water-permeable plastic, and its material is relatively soft. Due to long-term immersion in high-turbidity sewage, a large amount of suspended matter will adhere to its surface, resulting in the sewage in the cylinder. Entering the hollow interior of the filter element, and the water pump at the inlet is always pumping water, a pressure difference will be formed between the outside and the inside of the filter element, and the increasing pressure difference will eventually cause the filter element to twist and deform, resulting in a gap between the upper cover plate and the upper end of the filter element. There are gaps, so that the suspended matter in the sewage enters the filter element from the gaps, and the sewage filtration effect is greatly weakened
