Water purification system for pigpen

Abstract

The invention discloses a water purification system for a pigpen. The water purification system comprises a waste liquid storage tank, a biochemical reaction and sedimentation tank, an activated carbon adsorber, a flocculator, a biochemical purifier and an acid-base neutralization balancing device, wherein the liquid storage tank communicates with the biochemical reaction and sedimentation tank through a pipeline; the biochemical reaction and sedimentation tank communicates with the top of the activated carbon adsorber through a pipeline; the lower end of the lateral surface of the activated carbon adsorber communicates with the flocculator filled with polyacrylamide flocculant through a pipeline; the flocculator communicates with a liquid pump through a pipeline; the liquid pump communicates with the biochemical purifier; the biochemical purifier communicates with the acid-base neutralization balancing device through a pipeline; an acid-base liquid feed port is arranged at the upper end of the acid-base neutralization balancing device; and the lateral surface of the acid-base neutralization balancing device is provided with a liquid outlet pipe. Thus, the water purification system is reasonable in design and compact in structure; and hiccup sewage from a pigpen can be favorably treated, so that the cyclic utilization standard is achieved, thereby being beneficial to water saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a water purification system for pig houses. Background technique [0002] In pig breeding technology, in order to ensure the quality of large-scale breeding of pigs, every link needs to be standardized and large-scale. In the breeding process, in addition to suitable temperature, clean and tidy pig houses, and scientific feeding methods In addition, one of the more important links is that each pig house needs to ensure that the pigs can have safe, healthy, and pollution-free drinking water. Only when the daily drinking water of pigs can be healthy is guaranteed, is the high-quality pig breeding technology Prerequisites for large-scale farming. [0003] A clean pig house is conducive to the healthy growth of pigs, so it is necessary to wash the pig house with plenty of water frequently to keep the pig house hygienic. Due to the high value of pig manure, ...

AI Technical Summary

Problems solved by technology

Due to the high value of pig manure, a solid-liquid separator is generally used to separate the solid-liquid from the pig manure and urine after cleaning the pig house. If it is not treated, it will pollute the ecological environment and waste water resources.

Moreover, in the prior art, the sewage in the piggery is treated by a simple filter device so that it can meet the discharge standard, but it cannot be recycled.
