Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of printing and dyeing wastewater treatment system is divided into three parts, comprises comprehensive wastewater preprocessing system, degree of depth recycling processing system and sludge treating system.
1, comprehensive wastewater preprocessing system
The comprehensive wastewater preprocessing system at first carries out pre-treatment by pH regulator and coagulating sedimentation, adopt " acidication and biological contact oxidation process " secondary biochemical combined treatment process then, (COD ≦ 100mg/L), last second pond water outlet enters advanced treatment system to primary standard with wastewater treatment.
The comprehensive wastewater preprocessing system comprises equalizing tank 1, coagulative precipitation tank 2, blowoff basin 3, biological hydrolysis acidification pool 4, aerobic contact oxidation pond 5, radial-flow second pond 6 and the intermediate pool 7 that connects successively.
Comprehensive wastewater at first enters equalizing tank after collecting, the pond Inner Front End is provided with grille well 8, removes materials such as fiber, rubbish.Equalizing tank helps even water quality and quantity, guarantees subsequent disposal stability.Evenly the waste water behind the water quality and quantity carries out pH regulator, carries out coagulating by dosing coagulant, flocculation agent etc., removes partial organic substances, reduces follow-up biochemical treatment load and difficulty, and the flat flow preliminary sedimentation tank is set, and carries out precipitating action.
Pretreated waste water is squeezed into the biological hydrolysis acidification pool by blowoff basin, establish the contact filler in the biological hydrolysis acidification pool, to adhere to the heterotrophism aerobic-anaerobic microbe, reach the acidication stage, and be provided with the diving mixing and stirring system, prevent sludgd deposition, also help the abundant contact reacts of waste water and mud.Under double oxygen bacterium effect, making polymer and complicated organic matter degradation in the waste water is small molecules, simple organism, improves the biodegradability of waste water, improves follow-up aerobic biochemical treatment condition, and dyestuff is also had decolorization preferably.Simultaneously, follow-up aerobic mixed solution and second pond mud are refluxed, (dissolved oxygen is less than 0.5mg/L) carries out the denitrification biological denitrogenation effect under the oxygen condition of holding concurrently, and reduces the ammonia-nitrogen content in the waste water.
The acidication water outlet inserts the aerobic contact oxidation pond, carry out aeration (dissolved oxygen is about 1-2mg/L) by gas blower, utilize the microorganism (aerobic bacteria) that is in the pond under the suspended state that the organic pollutant in the waste water is adsorbed, decomposes, thereby reach the purpose of removing organic pollutant, purifying water.Aerobic Pond is provided with vortex shedding flow meter, can save working cost according to variable frequency control air quantity size.The water outlet of aerobic contact oxidation pond flows into the radial-flow second pond and carries out mud-water separation, and its water outlet is treated degree of depth Treatment for Reuse from flowing to intermediate pool.
In comprehensive wastewater pre-treatment process, can produce pollutions such as waste gas, noise, surrounding enviroment there is bigger influence, therefore increase the control of control of Sewage treatment systems waste gas and Sewage treatment systems sound pollution.
In the operation of sewage disposal system process, because the metabolism of microorganism can produce a certain amount of peculiar smell waste gas, pollute the ambient atmosphere environment, therefore, biochemical reaction tank (biological hydrolysis acidification pool, aerobic contact oxidation pond) is added cover plate, set up gas sampling treatment system 9, the gas with foreign flavor that produces in the biochemical system is taked to discharge after the centralized collection, to reduce pollution the ambient atmosphere environment.
In the biochemical treatment system operational process, need gas blower that air constantly is provided, produce bigger sound pollution, therefore the living environment that the influence periphery is lived, add silencing hood to gas blower, Ventilator Room adopted measures such as soundproof wall, soundproof window, reduces noise effect.
2, degree of depth recycling processing system
The waste water of intermediate pool is proceeded degree of depth Treatment for Reuse, degree of depth recycling processing system adopts two membrane treatment process technology of cleaning sand filtration and " the integrated film of adding pressure type UF ultra-filtration membrane and reverse osmosis (RO) " automatically to carry out degree of depth Treatment for Reuse, makes reuse water reach senior quality of reused water requirement.The reuse of advanced treatment and reclamation water is to production plant, and the membrane separation concentrated water of all the other degree of depth is received tube drainage according to grade III Standard.If emission standard improves, then membrane separation concentrated water can increase treatment facility in addition to be handled.
Degree of depth recycling processing system comprises automatic back-washing formula sand filtration system 10, adding pressure type ultrafiltration membrane system 11, RO film system (the integrated film processing system of RO reverse osmosis) 12 and the RO reuse pool 13 that connects successively;
Degree of depth recycling processing system is to be former water with biochemical second pond water outlet, is promoted through pump by intermediate pool and enters advanced treatment system, and the water outlet of intermediate pool is communicated with automatic back-washing formula sand filtration system.For guaranteeing the steady running of follow-up pair of film system, increase automatic back-washing formula sand filtration system at leading portion, materials such as the suspended substance in the further removal waste water, colloid, its water outlet enters the adding pressure type ultrafiltration membrane system by secondary filter again and removes bacterium, virus, organism and colourity etc. in the waste water, improve the integrated film processing system influent quality of follow-up RO reverse osmosis, prolong its work-ing life, guarantee overall depth reuse technology operation stability.The ultrafiltration membrane system water outlet enters the integrated film of RO reverse osmosis system, by the concentrating of RO film, interception capacity desalination, purifying effluent quality, for dyeing, the higher workshop section's reuse of stamp water water quality requirement.Film system dope reaches three grades and receives the tube drainage standard and can directly receive tube drainage.If emission standard improves, then membrane separation concentrated water can increase treatment facility in addition to be handled.
3, sludge treating system
Sludge treating system comprises sludge sump 14, the sludge outlet of radial-flow second pond is communicated with sludge sump, the radial-flow second pond produces mud and all inserts sludge sump, mud after the decrement is sent into the concentrated one pressure filter of belt by the mortar pump effect and is carried out processed, mud outward transport after the processing is handled, filtrate is inserted hydrolysis acidification pool, avoids producing secondary pollution.
More than disclosed only be several specific embodiments of the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
