Odor-resistant and flow-controllable sewage treatment equipment for paddy field fish culture

Abstract

The invention discloses odor-resistant and flow-controllable sewage treatment equipment for paddy field fish culture. The equipment includes a tank body, wherein a settling bin, a filtering bin and apurifying bin are mounted in the tank body; a water inlet pipe is mounted on one side of the top of the settling bin; a water inlet joint is mounted at the top end of the outer side edge of the tank body; one end, far away from the settling bin, of the water inlet pipe penetrates through and extends to the top end of the side edge of the tank body; a first water level sensor is mounted at the topend of one side edge in the settling bin; a first motor is mounted at the top of the settling bin and is positioned on one side of the water inlet pipe; a first rotating rod is installed at the bottomof the first motor, the bottom end of the first rotating rod penetrates through and extends into the settling bin, first stirring rods are symmetrically installed on the outer side edge of the firstrotating rod, and a first agent box is installed at the top of the settling bin and located on the side, away from the water inlet pipe, of the first motor.

Description

technical field [0001] The invention relates to the technical field of aquaculture sewage treatment, in particular to a kind of sewage treatment equipment with anti-odor and controllable flow rate for fish farming in paddy fields. Background technique [0002] Fish farming in rice fields is a kind of agricultural farming. Fish farming in rice fields mainly uses the water surface of rice fields to raise fish. It can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, and turn soil to promote fertilizer decomposition. To create good conditions for rice growth, in the process of paddy-fish farming, sewage needs to be treated to ensure better paddy farming; currently, in the process of paddy-fish farming, it is impossible to better treat sewage When processing, thereby affecting normal cultivation, it is also easy to produce peculiar smell, which affects people's work and surrounding environment, and then cannot better meet peo...

[0002] Fish farming in rice fields is a kind of agricultural farming. Fish farming in rice fields mainly uses the water surface of rice fields to raise fish. It can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, and turn soil to promote fertilizer decomposition. To create good conditions for rice growth, in the process of paddy-fish farming, sewage needs to be treated to ensure better paddy farming; currently, in the process of paddy-fish farming, it is impossible to better treat sewage processing, thereby affecting normal breeding, but also prone to odor, affecting people's work and the surrounding environment, and thus cannot better meet people's use needs
