Description

Integral type sewage treatment unit
Technical field
The utility model belongs to sewage treatment unit technical field, specifically, relates to a kind of integral type sanitary sewage disposal Device.
Background technology
According to " " 12 " whole nation urban wastewater treatment and the planning of regeneration Facilities Construction ", by the end of the year 2010, China city Town sanitary sewage facility disposal ability has reached 1.25 billion cubic meters/day, " 12 " period, the cities and towns in the planned range of the whole nation Newly-increased sewage disposal scale 4569 ten thousand steres/day.And along with the appearance of country's " water prevention and cure of pollution action plan ", water security Have gone up as national strategy, the important step that sewage disposal recycles as water body environment protection and water resource, need efficiently, Environmental protection, economic treatment technology and equipment.
Integral type sewage processing system is the important component part that domestic sewage factory focuses on pattern on a large scale, it is adaptable to villages and small towns, The diversifications of markets such as foreign-going ship sewage disposal, and the existing usual treatment effeciency of integral type processing system is relatively low, run control complicated, Financial cost is too high.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art to exist, and seeks to design a kind of one being applicable to remote countryside Formula sewage treatment unit, improves the treatment effeciency of dispersed wastewater, reduces the cost of rural sewage treatment, simplifies sewage Process technique.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of integral type sewage treatment unit, including inlet channel, aerated grit chamber, MBBR, anti-nitre Changing bioactivity filter, sterilization pool, described inlet channel is provided with grid, and inlet channel is connected with aerated grit chamber water inlet, aeration The delivery port of setting pot is connected with the water inlet of MBBR anaerobic zone;Described MBBR includes Anaerobic zone, anoxic zone and aerobic zone, anaerobic zone and anoxic zone wall altogether, it was provided with the mouth of a river, anoxic zone between anaerobic zone and anoxic zone With aerobic zone wall altogether, being provided with outlet pass between anoxic zone and aerobic zone, described aerobic zone is connected with aerator, and anaerobic zone is with good Oxygen is provided with inner loop pipeline between district;Described anaerobic zone and anoxic zone are filled with hard polyaminoester microbe carrier stuffing, described good Soft polyurethane ester microbe carrier stuffing it is filled with in oxygen district;The delivery port of MBBR aerobic zone is raw with denitrification The water inlet in thing activity filter tank connects, and the delivery port of denitrification bioactivity filter is connected with sterilization pool water inlet;Described sterilization pool It is provided with online chemicals dosing plant.
Preferably, the grizzly bar gap of described grid is 0.5-5cm, enters, at sewage, remove before aerated grit chamber in sewage miscellaneous Thing.
Preferably, between described anaerobic zone and aerobic zone, internal reflux ratio is 100%;
Preferably, in described denitrification activity filter tank, filter medium is particulate bioactive charcoal or polymer filtrate, under employing Run to stream mode;
Integral type sewage treatment unit of the present utility model, sewage, after grid, first passes through aerated grit chamber, by drum Blower fan aeration, phase mutual friction bear the shearing force of aeration between sand grains, the organic matter removal that will adhere on sand grains, the grains of sand are at eddy flow Centrifugal action is lowered into the husky sand launder of collection;Meanwhile, the dissolved oxygen that aeration provides is also beneficial to partial organic substances and removes.
Then sewage passes through MBBR, and a large amount of microbe carrier of this area filling, carrier has higher ratio table Area and bioaffinity, provide good apposition growth and the environment of propagation for sewage disposal microorganism, thus increase biomass, Improve sewage treating efficiency.Compared with traditional activated sludge process, MBBR (MBBR) sewage treatment load Height, excess sludge generation amount is few, it is adaptable to dispersant type domestic wastewater processes.Add specified microorganisms microbial inoculum, such as: denitrifying bacterium, Nitrifier etc., on microbe carrier stuffing cultivate be suitable to strengthen sanitary sewage disposal microorganism species, utilize carrier filler and The synergy of microbial bacterial agent, improves wastewater treatment efficiency further.
Sewage, through denitrification bioactivity filter, uses upward flow mode to run, and filtrate provides anaerobism for sewage disposal microorganism Living environment, beneficially denitrifying bacterium growth and breeding, thus strengthened denitrification effect further.
Last sewage flows through sterile zones, carries out by disinfection by ultraviolet light or by the way of adding sodium hypochlorite online, and water outlet reaches standard Can discharge.
The beneficial effects of the utility model are: be applicable to the distributing sanitary sewage disposal places such as remote villages and small towns, it is possible to efficiently process Sanitary sewage, water outlet can be directly discharged in natural environment;Solve traditional waste water treatment process control complexity, high in cost of production lacks Point
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
As shown in Figure 1: inlet channel 1, grid 2, aerated grit chamber 3, MBBR 4, denitrification biology are lived Property filter tank 5, sterilization pool 6, inner loop pipeline 7, aerator 8.
Detailed description of the invention
Combine accompanying drawing below by specific embodiment the utility model is further described:
