Description
Technical field
The present invention relates to sewage treatment area, more particularly, it relates to multifrequency sound energy generator, ultra micro acoustic energy integration dirt
Water treatment system and processing method.
Background technology
Along with development and the increase of population of industrial and agricultural production, lacking environmental protection consciousness, a large amount of have containing various in addition
The trade effluent of poison harmful substance and sanitary sewage is unprocessed or processes a little and just enters water body, causes water body and whole environment
Pollution.
Some problems that sewage disposal at present exists:
1, vast rural area and the Miniature Sewage Farm of urbanization residence district, the first is to the microorganism in sewage, floating
It is thorough that trip biology, mosquito wriggler etc. intercept, particularly temperature height mosquito in season wriggler and other worm's ovums etc. in parasitic water,
Biochemical reaction tank as continuous prolific hotbed, and it is not easy to kill, it is easier in Sewage Disposal and equipment week
Enclose and cause mosquito, fly to dance in the air, surrounding is caused secondary pollution；It two is that the process sewage volume of biochemistry pool is the most excessive；
2, Aerobic Pond oxygen supplement major part traditionally is all to use Aeration fan, and aeration head couples with aeration tube, carries out aeration
Oxygen supplement, ultra micro degree bubble little, ultra dense is intended to the target striven for, and the noise that blower fan produces is big, and solarization air cap easily blocks, and produces gas
Bubble particle diameter is big, dissolved oxygen (DO) is inefficient, and energy consumption is big；
3, in Aerobic Process for Treatment, it is all that the aeration of continuous equilibrium makes interior dissolved oxygen (DO) ring keeping balance and stability of Aerobic Pond
Border, meets the nitrification demand to oxygen, is so easily caused nitrifier long term accumulation, the generation of suppression Denitrification, it is impossible to realize
Anoxic denitrification, therefore, though certain ammonia nitrogen removal effect can be reached, but total nitrogen removal effect is poor, wants to carry out denitrification
Reaction, it is necessary to increase denitrification liquid reflux pump, which adds energy consumption and the expense of equipment；
4, sewage disposal is mostly to use liquid chlorine and chlorine tablets to throw in sterilization, is characterized in liquid chlorine low cost, technical maturity, effect
The most reliable and the most stable, shortcoming is to produce Chlorination Disinfection By-products, and abnormal smells from the patient is heavier, and storage and managenent requires strict, to equipment steel
Corroding more serious, maintaining is costly.
Chinese patent application, application number 201310288341.9, publication date on November 20th, 2013, disclose a kind of ultrasonic
Ripple synergistic oxidation sewage disposal device, by frame trough, regulating reservoir, ultrasonic synergistic oxidative system, accelerated oxidation response system, quiet
Put reaction precipitation system, medicine machine and control station composition, connected by water inlet pipe and water outlet pipe each other, regulating reservoir has regulation
Elevator pump, has PH reactor, concerted catalysis pneumatogen preposition, rearmounted in ultrasonic synergistic oxidative system, is accelerating oxygen
Change and have blender and sensor on reaction zone, A pond, reaction zone, B pond and reaction zone, C pond in response system, precipitate in standing and reacting
Rosette, water inlet electromagnetism, electromagnetic valve, draining pump and aeration is had on quiet A reaction zone in system, quiet B reaction zone and quiet C reaction zone
Pipe, has sulphuric acid dosing mouth on outlet pipe, and the water outlet after standing is aseptic nontoxic, tasteless colourless, as clear as crystal, is better than GB, can
Discharge or reuse, it is adaptable to hospital sewage, sanitary sewage, industrial wastewater, rivers and lakes sewage purification.But this programme disposal ability
Efficiency is low, and equipment is susceptible to blocking due to sewage reason, and maintenance rate is high.
Chinese patent application, application number CN03113303.7, publication date on October 1st, 2003, disclose a kind of aeration association
