Description

A kind of domestic sewage processing system

Technical field

The utility model is related to technical field of sewage, more specifically, it relates to a kind of domestic sewage processing system.

Background technology

With the continuous improvement of life of farmers level, rural area Income gap increasingly increases, quantity of wastewater effluent It is continuously increased.Such as cannot effectively administer, by severe exacerbation Rural Water Environment, and influence urban residents' quality of life.

At present, conventional technology for treating domestic sewage in rural area mainly has：Anaerobic biogas generating pit, artificial swamp, stabilization pond and soil Ground filtration system etc..Wherein anaerobic biogas generating pit processes domestic sewage in rural areas, and effluent quality can reach discharge standard, and can produce suitable In the fertilizer of agricultural production；Stabilization pond be make sewage it is natural or through in the artificial reconstructed or artificial pond built slowly flowing, Storage, by the metabolic activity of microorganism, the organic pollution in degraded sewage, so that sewage is purified；Artificial swamp The synergy of main microorganism and water plant by ecological treatment system, realizes the removal of pollutant；Land percolation System is to impose on soil sewage, and sewage is purified using the detergent power of soil, and the catharsis of soil is mainly wrapped Include filtering, the absorption in physical process, the organic matter degradation under chemical reaction and chemical precipitation and microbial metabolism effect etc..

Above technology can obtain good treatment effect when domestic sewage in rural areas is processed；But often there is occupation of land face Product is big, the low shortcoming for the treatment of effeciency, and water outlet does not reach the standard of reuse after treatment.And traditional activated sludge process and biomembrance process Deng when domestic sewage in rural areas is processed, capital construction and operating cost are located again higher than techniques such as artificial swamp, stabilization pond, land percolations Water outlet does not reach the standard of reuse yet after reason.

Regarding to the issue above, at present, the Chinese patent of Publication No. CN103771660A discloses a kind of life in the countryside dirt Water treatment system, its drip irrigation device is：Including reaction tank, the driving biological rotating disk of intaking, adsorption filtration device and ultraviolet Sterilizing unit, the driving biological rotating disk of water inlet includes multiple discs, and disc is by skeleton and the biomembrane being covered on skeleton Carrier is constituted, and the circumference of disc is provided with multiple intake chambers, and the intake chamber is top surface open containers, the multiple intake chamber Opening direction is identical；The driving biological rotating disk of the water inlet is erected at reaction tank top by rotating shaft, and the disc bottom It is always positioned in reaction tank；There are multiple water inlet pipes, the mouth of pipe difference of multiple water inlet pipes on the inlet pipeline being connected with source of sewage Position in it can inject water into the intake chamber on a disc, reaction tank delivery port is located at relative with water inlet Side, the delivery port of reaction tank is connected through adsorption filtration device with outlet pipe, and the ultraviolet sterilization device is arranged on outlet pipe.

This domestic sewage processing system passes through the organic matter in biofilm carrier absorption effluent, then will be with waste water portion The biofilm carrier for dividing is turned to be in contact with air and makes Organic oxidation, so that reaching the effect of purification sewage.But During work, because the easily deposition or absorption of the organic matter in sewage is in the bottom of pond and pool wall of reaction tank, therefore portion is had Dividing organic matter cannot be purified.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of domestic sewage processing system, With treatment organic matter more thoroughly advantage.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of sanitary sewage disposal System, including filled in the circular arc reaction tank for setting, intake driving biological rotating disk, adsorption filtration device and ultraviolet-sterilization Put, driving biological rotating disk of intaking includes that the rotating shaft being rotatably connected on the reaction tank and multiple are fixed in the rotating shaft Purification disk, the purification disk includes being fixed on the skeleton of the rotating shaft and the biofilm carrier being coated on the skeleton outer wall； The circumference of the purification disk is provided with multiple water inlet components, connecting plate that the water inlet component includes being fixed on the skeleton, The fixed plate being fixed on the connecting plate, the intake chamber being formed between the connecting plate and the fixed plate, described in each Cleaning board is fixedly connected with fixed plate, the cleaning board is provided with Clean Brush for cleaning, the Clean Brush for cleaning and the reaction tank Pool wall it is inconsistent.
