Abstract

The invention discloses feces wastewater treatment equipment. The feces wastewater treatment equipment comprises an oxidizer preparation chamber, an oxidation chamber, a first filter chamber and a second filter chamber, wherein the oxidizer preparation chamber is internally provided with an iron anode and an inert cathode, electric wires of the iron anode and the inert cathode extend out of the oxidizer preparation chamber and then is connected with a power supply connecting terminal, the oxidizer preparation chamber is provided with an electrolyte inlet, and the electrolyte inlet communicateswith the interior of the oxidizer preparation chamber; the oxidizer preparation chamber communicates with the oxidization chamber through a first pipeline; a feces wastewater inlet is formed in the top of the oxidation chamber; the first filter chamber is internally provided with a micron-sized filter, and the oxidation chamber communicates with the upstream part of the micron-sized filter of thefirst filter chamber through a second pipeline; and the second filter chamber is internally provided with a nano-sized filter, and a filtrate outlet of the nano-sized filter communicates with the upstream part of a micron-sized filter in the second filter chamber. According to the feces wastewater treatment equipment, use of microorganisms is avoided, the bacterium killing rate is high, the working process is not limited by the ambient temperature, and immediate treatment of feces wastewater is realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and environmental protection, in particular to equipment for treating fecal sewage. Background technique [0002] Fecal sewage refers to the washing water excreted by residents in their lives, and it is defined as domestic sewage containing fecal matter, such as toilet flushing water. Fecal sewage is a typical high-concentration organic sewage. The basic task of fecal sewage treatment is to remove various organic substances. The existing fecal sewage treatment methods are mainly biological treatment methods, which use the life activities of microorganisms to degrade the organic matter in the dissolved or colloidal state in the sewage, thereby purifying the sewage. This method requires a large area of ​​equipment, strict temperature requirements, long treatment time, and low sewage treatment efficiency. Therefore, the traditional fecal sewage treatment system needs to be improved. [000...
