A microbial fuel cell system with a built-in fish tank that realizes self-cleaning function

Abstract

The invention discloses a microbial fuel cell system internally provided with a fish tank for realizing a self-cleaning function. The system comprises the fish tank, a microbial fuel cell device integrated in the fish tank, an anode, a cathode and an electrically driven fish tank supporting device, wherein the microbial fuel cell device comprises an anode module, a cathode module and an aeration device which consists of an air pump and an air duct and provides oxygen for the cathode module. According to the system, a microbial fuel cell is inserted into the fish tank, no external force or additional energy source is required, microbial utilization and conversion of organic matter waste deposited in the fish tank are realized under the condition that an ornamental value of the fish tank is not influenced and an activity of fish is not disturbed, a clean ecological environment in the fish tank is maintained, and electric energy is produced to drive the fish tank supporting device (such as the air pump and an LED (light-emitting diode) lamp tube), so that a self-cleaning microecological cycle system is formed.

Description

[0001] Technical field: [0002] The invention relates to the fields of micro-ecological environment and clean energy, in particular to a microbial fuel cell system with a built-in fish tank that realizes self-cleaning function. [0003] Background technique: [0004] During the use of conventional fish tanks, fish feces, residual fish food, moss and other organic dirt will be deposited on the bottom, which will deteriorate the water quality and cause many problems such as affecting the health of fish and viewing effects. At present, the cleaning methods for residues mainly include: 1. Using "scavenger" fish, this type of fish feeds on the dirt generated by the glass and corners of the fish tank, but they do not eat feces, but produce more feces , so it is impossible to clean the fish tank simply with "scavenger"; 2. Use siphon combined with brush and filter to clean. This cleaning method is more thorough, but the steps are cumbersome, time-consuming and laborious, and need to ...

Problems solved by technology

[0006] In order to solve the problem of unsatisfactory cleaning effect, cumbersome cleaning steps and energy consumption of fish tank waste in the prior art, the present invention provides a microbial fuel cell system with a built-in fish tank that realizes self-cleaning function, and integrates an organic waste in the fish tank The micro-ecological self-circulation system of self-cleaning treatment and energy generation uses the organic waste in the fish tank as the processing object and raw material, and converts the chemical energy in the organic waste into electrical energy through microbial catalysis, which is supplied to the fish tank itself, so as to realize the Self-cleaning and energy-saving and environmental protection functions
