Rural integrated wastewater treatment tank

Abstract

The invention discloses a rural integrated wastewater treatment tank. The treatment tank comprises a tank body, a guardrail and a body protection ladder stand, a stirring device is mounted in the middle of the top end of the tank body, a gas stripping destroying pipe is mounted at the top end of the tank body, the lower end of the gas stripping destroying pipe is connected with a return pipe, theside of the gas stripping destroying pipe is connected with a gas stripping lifting pipe, and the lower end of the gas stripping lifting pipe is provided with an opening which can better collect an air-water mixture to form a gas stripping effect. A three-phase separation device and an aeration device are arranged in the tank body, the three-phase separation device is provided with an adjustable center cylinder, an overflow weir is arranged at the top end of the inner wall of the tank body, and the overflow weir can be arranged to be a pi-shaped overflow weir or be arranged to be in a circumferential shape around the inner wall of the tank body, and reinforcing plates are evenly distributed at the bottom of the tank body to enhance the strength of the tank body. The vertical tank body is adopted, so that the occupied area is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rural integrated wastewater treatment tank. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment equipment is also applied to more fields such as construction, medical treatment, transportation, agriculture, etc., but the current sewage treatment equipment There are problems such as low processing efficiency, unstable operation, large floor space, and inability to adjust in time. [0003] After searching, the authorized announcement number: CN209411883U, the patent name: the Chinese patent of internal circulation biological reaction tank, discloses a vertical tank equipment that uses a three-phase separator, aeration head assembly and pipe assembly to treat sewage. However, the processing efficiency of the equipment is low and c...
