[0022] Embodiment:

[0023] Please refer to Figures 1-3 The present application provides a technical solution:

[0024] A small integrated rural sewage treatment device, comprising a shell 1, a first box 2 is fixed to the left end inside the shell 1, a filter tank 3 is fixed to the upper side of the first box 2, a first water passage is formed in the lower side of the filter tank 3 and the upper side of the first box 2, a fixed plate 4 is fixed to the left end and the right end of the inner wall of the filter tank 3, a filter screen 5 is horizontally arranged on the upper end of the two fixed plates 4, by arranging the filter screen 5, hair, fiber impurities, soap bubbles and the like generated in the process of washing, bathing and the like can be intercepted, the filter screen 5 can be disassembled and replaced after long-term use, an iron-carbon micro electrolysis filler box 6 is fixed in the first box 2 through a fixing frame, a top cover 7 is clamped on the upper side of the shell 1, the top cover can be disassembled, a sewage discharge pipe 8 is fixed to the side wall of the top cover 7;

[0025] Sponge iron is a common sewage treatment material, which is obtained by grinding and magnetic separation of iron ore concentrate, sintering under a temperature lower than the melting temperature of iron, cooling, washing, crushing, and then re-magnetic separation and screening. Sponge iron has the advantages of large specific surface area, high metal iron content, stable structure, and fast reaction speed, and is an excellent iron filings material.

[0026] The electrolytic material of the iron-carbon micro-electrolysis process is a dense multi-hole long strip material made of sponge iron and activated carbon mixed together.

[0027] There is a standard electrode potential difference of 1.2V between iron in sponge iron and activated carbon. The coexistence of the two in wastewater can form a large number of micro-batteries. Among them, iron and carbon act as anode and cathode respectively, and can form the following reactions:

[0028] Anode reaction: Fe-2e - → Fe 2+ ;

[0029] Cathode reaction: 2H + +2e - → H2, O2+2H + +2e-→ H2O2

[0030] In the battery reaction, Fe 2+ is generated at the anode and H2O2 is generated at the cathode, thereby generating active [H] atoms, which in turn undergo redox reactions with pollutants in wastewater. Fe 2+ can reduce nitro (NO2) and nitroso (NO) organic matter, which is difficult to degrade, into amine (NH2) organic matter, which is easier to degrade. [H] atoms can break and open the rings of long-chain or benzene ring-containing organic matter, greatly reducing the biological toxicity of wastewater.

[0031] As the micro-electrolysis reaction proceeds, the pH of the wastewater gradually increases, and Fe 2+ and Fe 3+ generated at the anode generate Fe(OH)2 and Fe(OH)3 colloidal substances with strong flocculation ability under alkaline conditions, which can more effectively adsorb pollutants in wastewater, thereby enhancing the purification effect on water bodies.

[0032] The right side of the first box body 2 is fixed with the second box body 9, the upper side of the second box body 9 is fixed with the third box body 10, the upper end of the right side of the first box body 2 is fixed with the clean water discharge pipe 11, the inside of the third box body 10 is fixed with the ozone generator 12, the upper side of the third box body 10 is fixed with the oxygen inlet pipe 13, the lower end of the oxygen inlet pipe 13 is fixedly connected with the upper side of the ozone generator 12, the lower side of the third box body 10 is fixed with the ozone ventilation pipe 14, the other end of the ozone ventilation pipe 14 extends to the inside of the iron-carbon micro-electrolysis filler box 6, the lower side of the first box body 2 is provided with the second water flow channel, the ozone method has better impact load resistance than other processes, and the production quality is stably improved; the colority can be significantly reduced, the dissolved oxygen content in water can be improved, the COD removal effect is higher, and the biodegradability is improved; the ozone aeration process can prevent the carbon-iron micro-electrolysis reactor filler from being hardened, effectively kill bacteria, and inhibit the generation of hydrogen sulfide, ammonia and other foul-smelling gases. The ozone method does not produce sludge and does not cause secondary pollution.

[0033] The lower end of the left side of the shell 1 is fixed with the maintenance water outlet pipe 15, the upper end of the maintenance water outlet pipe 15 is fixed with the disassembly baffle 16, the disassembly baffle 16 can be disassembled, and the impurities in the inside are treated, and the lower end of the right side of the shell 1 is fixed with the clean water outlet pipe 17.

[0034] The right end of the upper side of the first box body 2 is inserted with the balance gas pressure pipe 18, the balance gas pressure pipe 18 can be disassembled, and the upper end of the balance gas pressure pipe 18 extends to the upper end of the shell 1.

[0035] The side walls of the filter screen plate 5, the top cover 7 and the disassembly baffle 16 are fixed with handles.

[0036] The lower end of the first box body 2 and the left end of the second box body 9 form a water storage cavity.

[0037] The pipe walls of the maintenance water outlet pipe 15 and the clean water outlet pipe 17 are provided with switch valves.

[0038] Working principle:

[0039] Sewage from sewage discharge pipe 8 enters the inside of filter tank 3, sewage flows through filter screen 5, and the first heavy rough filtration is completed by filtering floating foam and hair; sewage is collected into first box 2, the water level line is raised and passes iron-carbon micro electrolysis filler box 6, and the second heavy filtration is carried out by the reaction of sewage and carbon iron filler; when the water level line reaches water discharge pipe 11, the oxygen-rich water is naturally reacted in second box 9, and the escaped oxygen is discharged from balance pressure pipe 18 to the outside of shell 1; when the user needs to use water, the switch valve of water outlet pipe 17 can be opened to take water; ozone generator 12 is powered on for a predetermined time, and ozone generator 12 starts to work; ozone enters first box 2 along ozone inlet pipe 14 to carry out the third heavy purification on sewage, and ozone not only has sterilization and disinfection effects, but also promotes the reaction of carbon iron micro electrolysis.

[0040] Three heavy purifications:

[0041] By setting the first heavy filtration screen 5, special material filter cloth or metal mesh is used as the component, which has the characteristics of high filtration precision, fast filtration speed and acid and alkali corrosion resistance. It can intercept hair, fiber impurities, soap bubbles and the like generated in the process of washing water, bathing water and the like;

[0042] And through the iron-carbon micro electrolysis filter component in the second heavy filler box, the surfactant, color, residual chlorine and the like in the sewage are adsorbed and removed, sponge iron has the characteristics of electrochemical enrichment, physical adsorption and flocculation and precipitation, and has a certain removal effect on nitrogen and phosphorus pollutants in washing sewage;
