Embodiment 1

[0010] figure 1 It is an explanatory diagram showing the steps of a sewage biochemical filtration method of the present invention. Such as figure 1 As shown, the above-mentioned treated liquid is sucked by the above-mentioned liquid pump 1 and pumped into the above-mentioned carbon metal electrochemical reaction device 4 through the above-mentioned flow meter 2 and the jet micro-aeration device 3. In the above-mentioned carbon metal electrochemical reaction device 4, the following The above-mentioned carbon and metal scraps are the main components of the filler, and the above-mentioned jet micro-aeration device 3 sucks in an air volume of 0.1-0.6 m3 / m3 of the liquid to be treated min, and is unevenly distributed in the above-mentioned carbon metal electrochemical reaction device 4 . Based on this, the above liquid to be treated is mixed with the filler to form a macroscopic and microscopic short-circuit battery, and electrochemical biochemical reactions occur, including anode...

Embodiment 2

[0013] The treated liquid containing anionic surfactant is purified by internal electrolytic magnetic coagulation method: the treated liquid with a pH value of 4-7.5 CODcr1000-1400mg / L is pumped into the carbon metal electrochemical reaction device 4, and filled with carbon metal Filler based on swarf, make the liquid to be treated react in the above-mentioned carbon metal electrochemical reaction device 4 for 30min, and the temperature is controlled at 18-33°C, after neutralization and magnetic coagulation tank for neutralization and magnetic coagulation, and then The phase separation tank 6 separates the liquid phases. After purification based on this step, the chroma removal rate of the treated liquid is >98%, the removal rate of suspended solids is >90%, the CODcr removal rate is >90%, the output rate of magnetic substances is 20-100 mg / L h, and the sludge contains water The rate is 88-90%. The object of purification treatment of the present invention is industrial and do...

Abstract

A biochemical sewage filtration method includes the steps of carbon metal electrochemical reaction, magnetization, flocculation, magnetic coagulation, liquid phase separation and the like, wherein carbon metal scraps are added in a carbon metal electrochemical reaction device to serve as main filler, the internal temperature of the reaction device is controlled to be within 18 DEG C-33 DEG C, and the pH value is controlled within 4-7.5. Natural electrolytic magnetization is achieved, and the biochemical sewage filtration method is efficient, capable of saving energy, ecological and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of environmental protection regenerated water treatment, and in particular relates to a sewage biochemical filtration method. Background technique [0002] At this stage, there are two types of electrochemical and biochemical treatment technologies for sewage: auxiliary current electrolysis and internal electrolysis. The internal electrolysis method uses the principle of a micro-battery formed by a substance with a potential difference to purify the liquid. While saving energy, the efficiency is unstable, so. The invention designs a liquid electrochemical biochemical filtration method without auxiliary current. Contents of the invention [0003] A sewage biochemical filtration method designed in the present invention is based on carbon metal electrochemical reaction, flocculation, magnetic coagulation, liquid phase separation and other steps. The micro-aeration device adds air for mixing, enters the inte...
