Abstract
The invention discloses a biofilm active sand reactor and a wastewater treatment method thereof. The biofilm active sand reactor comprises a main body, a water inlet pipe, an effluent weir, a filter material, a water distributor, a sand guide cone, an air lifting pump, a sand lifting air nozzle, a sand lifting pipe, a sand washer, a sand washing water outlet and an electric control system. The wastewater enters through the water inlet pipe and is uniformly distributed by the water distributor; the wastewater goes adversely from bottom to top and goes through the filter material; impurities in the wastewater are filtered, and the turbidity and chroma in the wastewater are effectively removed. By adopting the reactor and method disclosed by the invention to treat wastewater, the reactor covers a small area, the backwashing efficiency of a filter material is high, and the filter material is not hardened; by wrapping the filter material with a biofilm, an effect of removing organic pollutants in the wastewater is realized; moreover, the chroma and turbidity removal effect of the whole system is more remarkable due to microorganisms. After the treatment, the COD (chemical oxygen demand), turbidity and chroma in the water reach or exceed the first-class A standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002).
Description
Technical field
The invention belongs to advanced treatment of wastewater, micro-polluted water field of purification, particularly a kind of sewage reactor and the method for disposing of sewage thereof.
Background technology
At present, the most of urban wastewater treatment firm of China is all to adopt " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level B mark emission standard, as long as qualified discharge is little to environmental influence.But along with the fast development of Chinese society economy, urban population increases severely, cities and towns daily water consumption is anxious to be increased, and wastewater emission amount is obvious ascendant trend in recent years, and this causes larger pressure to some regional environment.Under these circumstances, if also by one-level B mark operation sewage work, nitrogen phosphorus etc. accumulates over a long period in water body, particularly be discharged into sealing water body, can cause body eutrophication, to the dry period in summer, water quality deterioration is serious especially, the eubiosis is destroyed, and what make the masses is healthyly subject to great impact.
At present, adopt new technology, new installation is urban wastewater treatment firm putting forward a kind of technique means in mark transformation.Filtration is the key link in sewage disposal, there is the problems such as floor space is large, filtrate back flushing efficiency is not high, filtrate can harden in conventional filter, active sand filter is a kind of Collecting flocculation, clarify, be filtered into the continuous filtration equipment of one, and conventional filter has that floor space is little, energy consumption is low, back flushing is cleaned thoroughly, filtrate can not harden, can bear load advantages of higher relatively.But simple active sand filter is limited to organic pollutant processing power, be difficult to meet the actual needs that use.
Therefore, be badly in need of a kind of waste disposal plant and sewage water treatment method and overcome above-mentioned defect.
Summary of the invention
A kind of method that the object of this invention is to provide biomembrane activity sand reactor and dispose of sewage, to solve that the floor space that exists in prior art is large, filtrate back flushing efficiency is not high, filtrate can harden and to the limited problem of organic pollutant processing power.
For achieving the above object, the present invention is by the following technical solutions:
A kind of biomembrane activity sand reactor, comprise main body, water inlet pipe and effluent weir, filtrate is housed in main body, main body middle part arranged outside has water inlet pipe, water inlet pipe below is connected with water distributor, water distributor below is connected with leads maracas, main body top one side is provided with effluent weir, and body interior is vertically provided with sand extraction tube, and sand extraction tube epimere outer setting has sand-washing device, on sand-washing device, be connected with washed-out sand water out, washed-out sand water out is positioned at described effluent weir bottom, and the external air lift of sand valve, for carrying sand valve, is carried in sand extraction tube lower end.
Air lift is connected with electric control system.
Sewage is passed into by water inlet pipe, and through water distributor uniform water distribution, sewage is flowed to upper by subinverse, flows out from the effluent weir at top through main body; Lead abrasive cone and will hold back the filtrate guide body bottom of pollutent; Air lift cleans to carrying sand valve air compressing for dirty filtrate is promoted to sand-washing device by sand extraction tube, washed-out sand water is flowed out by washed-out sand water out, and the filtrate being cleaned comes back to main body and enters next circulation; Electric control system, for controlling startup, operation and the warning of biomembrane activity sand reactor and air lift, reaches the operation of biomembrane activity sand reactor autostable and automatic intermittent washed-out sand.
Filtrate is particle diameter 10 ~ 20 object granulated active carbons.
Granulated active carbon is wrapped with microbial film.
The beneficial effect of the invention is: adopt biomembrane activity sand reactor provided by the invention and the method for disposing of sewage is processed sewage, first biomembrane activity sand reactor floor space is little, next filtrate back flushing efficiency is high, filtrate can not harden, when can realizing general system for filtering active sand filteration, on filtrate, outsourcing microbial film has reached the effect of removing dirty organic pollutants, and microorganism makes whole system more remarkable to the removal effect of colourity, turbidity.
COD, turbidity, colourity after processing in water reaches or is better than the one-level A standard in " urban wastewater treatment firm pollutant emission standard " (GB 18918-2002).
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-filtrate, 2-water inlet pipe, 3-water distributor, 4-effluent weir, 5-leads abrasive cone, 6-air lift, 7-carries sand valve, 8-sand extraction tube, 9-sand-washing device, 10-washed-out sand water out, 11-electric control system.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, a kind of biomembrane activity sand reactor, comprise main body, water inlet pipe and effluent weir, filtrate 1 is housed in described main body, described main body middle part arranged outside has water inlet pipe 2, water inlet pipe 2 belows are connected with water distributor 3, water distributor 3 belows are connected with leads maracas 5, described main body top one side is provided with effluent weir 4, described body interior is vertically provided with sand extraction tube 8, described sand extraction tube 8 epimere outer setting have sand-washing device 9, on described sand-washing device 9, be connected with washed-out sand water out 10, described washed-out sand water out 10 is positioned at described effluent weir 4 bottoms, described sand extraction tube 8 lower ends are for carrying sand valve 7, the described external air lift 6 of sand valve 7 of carrying.
