Farming sewage treatment device

Abstract

The invention discloses a breeding sewage treatment device, which comprises a separation unit, a sedimentation unit, a fermentation unit, a flocculation unit, and a filter unit connected in sequence; the separation unit includes a liquid inlet mechanism, a liquid outlet mechanism, a centrifugal mechanism, a solid phase discharge mechanism, a machine frame; the centrifugal mechanism includes a rotating shaft, rotating blades, a solution box, a power turntable, and a servo motor; the liquid outlet mechanism includes a water inlet pipe, an outlet pipe and a water pump; the liquid inlet mechanism communicates with the bottom of the solution box; the solid phase The discharge mechanism includes a control housing, a ring gear, a solid gear, and a control motor. The invention can decontaminate the moisture in the breeding sewage, so that the breeding sewage no longer pollutes the environment.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an aquaculture sewage treatment device. Background technique [0002] The aquaculture industry has always been a traditional industry in agriculture. With the improvement of people's living standards, the demand for meat products is also increasing, resulting in large-scale aquaculture. [0003] Compared with traditional farming, large-scale farming has a higher breeding density and a larger total amount, which will produce more feces. At the same time, since large-scale farming uses feed farming, the feces produced by livestock such as geese and ducks will enrich the water body. Nutritization, which will have a greater impact on the environment. [0004] Therefore, in order to minimize the impact of aquaculture sewage on the environment, it is necessary to treat the aquaculture sewage to a certain extent, usually by separating the aquaculture sewage from wet and dry, so that the aqua...

[0003] Compared with traditional farming, large-scale farming has a higher breeding density and a larger total amount, which will produce more feces. At the same time, since large-scale farming uses feed farming, the feces produced by livestock such as geese and ducks will enrich the water body. Nutritization, which will have a greater impact on the environment

[0004] Therefore, in order to minimize the impact of aquaculture sewage on the environment, it is necessary to treat the aquaculture sewage to a certain extent, usually by separating the aquaculture sewage from wet and dry, so that the aquaculture sewage can be reprocessed to reduce environmental pollution. Wet separation is realized in the form of a filter, and the liquid is discharged through the holes of the filter to achieve solid-liquid separation. This method has the problems of low processing efficiency and high cost; there is also a natural precipitation method to achieve solid-liquid separation. , the liquid is discharged by other means, and the solid is collected by the scraper

The relatively dry feces produced by filtering the dewatered aquaculture sewage can be dried again as fuel or directly transported long-distance as fertilizer. The remaining water needs to be treated again, otherwise it will be directly discharged into the environment, which will cause serious damage to the environment. big damage
