Description
The utility model is a kind of equipment that is applied in the supply and drain water system, particularly to the improvement of the structure of reactor in the Sewage treatment systems.
Useless (dirt) water of China is mainly derived from trade effluent, agricultural effluent and three aspects of sanitary wastewater at present; Be divided into organic waste water and inorganic wastewater technically again.Existing main treatment technology to organic waste water has a kind of membrane separation process (membrane filtration), and its formation is, in the both sides of filtering membrane the negative pressure rising pipe is arranged, and the filtering membrane of being made by nanometer materials between the negative pressure rising pipe is communicated with, and filtering membrane is a tubulose, has through hole.Sewage enters in the pond, filters by filtering membrane, and the through hole by filtering membrane enters the negative pressure rising pipe again, makes sewage purification.This equipment does not have the active biochemical reaction, has only a filtering function, causes this equipment to filter purifying waste water of producing and can not reach the reuse water requirement, can only reach emission request.
The purpose of this utility model provides a kind of combined pressure ultrafiltration bio-reactor that can reach the reuse water requirement.
The purpose of this utility model is to realize like this.By pressurization aerobic-anaerobic activated sludge working lining and the two integrated combining of built-up type NM ultrafiltration pipe.Combined pressure ultrafiltration bio-reactor, the inner bottom part of reaction ultrafiltration cylindrical shell 5 is fixed with water distribution (gas) plate 4; The outer bottom of cylindrical shell 5 is fixed with air water mixture control 3; The air water mixture control is communicated with air valve 1 and reducing valve 2, and inlet pipe 13 is communicated with reducing valve 2 and air valve 9 respectively; Air valve 9 and water valve 11 are communicated with on the through hole on the cover 8; Through hole on the cover 8 is fixedly connected to go out water pot 7; Go out water pot 7 for oblate, be communicated with ultrafiltration pipe 6 on its bottom surface; Ultrafiltration pipe 6 is made up of two portions, and a rigid support that has a gap is arranged, and support is wrapped with the filtering membrane that nanometer materials are made; The ultrafiltration pipe is positioned at the middle part of cylindrical shell; Mud recycle control valve 12 is installed in the middle part of cylindrical shell 5 outer walls.
Go out and be communicated with a plurality of ultrafiltration pipes 6 on the water pot bottom surface; The rigid support that has the gap can be that band foraminous pipe constitutes on the outer wall; Or constitute the support that has the gap with the muscle of a plurality of bar shapeds.
Air valve 1, air valve 9, water valve 11, mud recycle control valve 12 can be magnetic valve or butterfly valve, or gate valve.Through hole internal fixing on the cover 8 has the tube of gap bridge 10; Pass a bridge tube with go out water pot 7 and fixedly connected.
The utility model mainly is applicable to treatment of Organic Wastewater, and in need doing the high organic waste water of the soda acid number of degrees and pre-treatment work.Principle of work of the present utility model is, the sewage in the initial adjustment pond flows into the carbonated drink mixture control 3 of this device by pump through piping, enters reaction ultrafiltration cylindrical shell 5; Air valve 1, air valve 9 and water valve 11, mud recycle control valve 12 are closing condition at this moment.Before this running, combined pressure ultrafiltration bio-reactor is filled with the water purification bacterial strain of having been tamed.This bacterial strain can be under pressure state 25～30bar works better, also can be in works better under the atmospheric pressure state.This moment, sewage carried out the active biochemical reaction under pressure state.After pump shuts down, at this moment, be full of sewage substantially in the reaction ultrafiltration tube, air valve 1 is opened, and pressurized air enters in the reaction ultrafiltration cylindrical shell through gas-water mixer 3, opens outlet valve 11 simultaneously.This state is called the active reaction state, and the length of sewage and aerobic water purification bacterium reaction time depends on the volume and the sewage pollution substrate concentration that react ultrafiltration cylindrical shell 5.Pressure active biochemical reaction by certain hour makes sewage obtain good flocculation.Because after the air inlet, sewage filters through ultrafiltration pipe 6 earlier, enters into out water pot 7,, carry out initial water outlet discharging by water valve 11 through the tube 10 of passing a bridge.After the residence time arrives, the pump starting, sewage enters reaction ultrafiltration cylindrical shell again.Filter the water outlet effect that can obtain satisfaction through micropore ultrafiltration pipe.After the treatment scale decision of reaction ultrafiltration cylindrical shell, can accomplish to intake simultaneously air inlet simultaneously by computer control; Can not intake single air inlet yet; Also can not air inlet, singly water inlet.Decide operation scheme by raw water quality and aquifer yield.Through after the processing of certain hour, may be covered with active sludge on the ultrafiltration pipe 6, aquifer yield is descended, be reacted on the instrument, open by instrument one control air valve 9, ultrafiltration pipe 6 is carried out blowback.During blowback, intake pump quits work, and outlet valve 11 is closed, and air valve 9 and mud recycle control valve 12 are opened, and enter the blowback state.Mud refluxed and entered the returned sluge settling tank this moment.The mud concentrated solution flows into the sludge acclimatization pond, enters pump again, enters combined pressure ultrafiltration bio-reactor through pump.The blowback time afterwards, enters the water treatment recurrent state generally at 1～2 minute
The utlity model has active biochemical reaction and filtering dual-use function.Because active reaction is carried out under pressure state, is equivalent to the deep water aeration, under the pressure condition of 25～30bar, its dissolved oxygen rate height, the utilization ratio of oxygen can reach 55～60% (common aeration is 10%), and dynamic efficiency can reach 1.8～2kg/kwh.Because the dissolved oxygen rate height, this apparatus structure is simple, and equipment volume is little, and floor space is few, can reduce investment outlay.The membrane filtration that adopts, and be oxygen condition, so filtering membrane is difficult for stopping up; Adopt the blowback method, spoil disposal need not increase miscellaneous equipment voluntarily.This equipment filters the purification that produces can reach the reuse water requirement.
The utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the utility model structural representation.
