Problems solved by technology

Wastewater returning technology can maximize the control of pollutants, improve soil fertility, and consume less energy, but it requires special personnel to manage it. There are certain restrictions on the area and the scale of the pig farm; the factory treatment technology is mainly divided into biological treatment, chemical treatment and physical treatment, and the relative cost is relatively high

Abstract

The invention relates to a microbiological fuel cell-based pig farm wastewater treatment system. The system comprises a manure collecting tank, a mechanical grid filtering tower, a water collecting tank, an equalizing tank, an anaerobic tank, a microbiological fuel cell, an equalizing tank, a microbiological fuel cell reactor, an active carbon filtering tower and a drained water tank which are sequentially arranged according to a wastewater treatment sequence, and all above parts are connected through a water conveying pipe in order to realize wastewater circulation; and the manure collecting tank is connected with the mechanical grid filtering tower through a water pump to realize the wastewater circulation. The system combines the microbiological fuel cell with a traditional wastewater treatment technology, so the system can be applied in treatment of pig farm wastewater to recover the electric energy and realize wastewater treatment.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a pig farm wastewater treatment system based on microbial fuel cells. Background technique [0002] In recent years, the pig farm wastewater produced by large-scale pig farm breeding has affected the surrounding ecology and atmospheric environment. Pig farm wastewater is high-concentration organic wastewater, which will not only pollute groundwater sources and surface water, but may also cause the land to lose its productive capacity, resulting in no green grass growing in some areas, dry trees, and even the possibility of spreading diseases, causing serious damage to human health. harm. [0003] In order to improve the pig farm environment and its negative impact, many technologies and methods have been used to treat pig farm wastewater, which are mainly divided into three categories: wastewater returning to the field technology, natural treatment technology and factory trea...
