Sewage processing equipment

Abstract

The invention belongs to the technical field of drinking water processing, and discloses sewage processing equipment. The sewage processing equipment comprises a raw water tank, a PAC drug adding device, a tank body, and a clear water tank; the tank body comprises a mixing chamber; the mixing chamber is arranged at the bottom of the tank body; a sterilizing chamber is arranged above the mixing chamber; aeration chambers are arranged on the two sides of the sterilizing chamber; the upper part of the sterilizing chamber is provided with an overflow port communicated with the aeration chambers; the upper of each aeration chamber is provided with a flow channel used for communicating the two aeration chambers; a first filter chamber and a second filter chamber are arranged above the flow channel; the first filter chamber and the second filter chamber are communicated with the flow channel through pneumatic gate valves; the pneumatic gate valves are used for controlling the first filter chamber and the second filter chamber; a first disinfecting chamber is arranged above the first filter chamber, a second disinfecting chamber is arranged above the second filter chamber; and the first filter chamber and the second filter chamber are isolated from each other by a separating plate arranged between the first filter chamber and the second filter chamber. The sewage processing equipment is provided with the two filter chambers, the pneumatic gate valves are used for controlling switching, and working efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of drinking water treatment technology, in particular to sewage treatment equipment. Background technique [0002] The water quality protection situation of rural drinking water sources in China is severe, mainly manifested in the prominent problem of natural poor-quality water and the increasingly serious pollution of rural drinking water sources. Among them, the main pollution sources of the rural water environment include pollution from township enterprises, excessive and unreasonable use of chemical fertilizers and pesticides, pollution from farms, solid waste pollution, and backward rural sewage treatment infrastructure. Therefore, Escherichia coli and nitrite nitrogen in drinking water directly affect the water quality and further affect people's health. The prior art discloses an invention with an application number of 201310114028.3, an application publication number of CN 104098220A, and an applicat...
