CXAF series of the CAF precipitation machine
First, an overview
As we all know that industry is an important part of the national economy, industrial development and national economic development is the basic synchronization; chemical, paper, leather, machinery manufacturing, printing and dyeing, metallurgy enterprises in the development of the efflux of wastewater on the environment significant pollution, sewage treatment is imminent event.
However, due to the long-standing lack of environmental awareness, coupled with insufficient investment in China's paper industry, while in the rapid development of the environment caused increasingly serious pollution hazards, in particular, the hazards of the water environment is staggering.
When the people awaken from the "treatment after pollution" on the road, to have caused the pollution control, the first mature technology for easy reference the governance or the governance of the outfall outside the factory, that is applied in the treatment of sewage has accumulated technology, convection sent to the sewage plant outfall to carry out a precipitation purification, two biological aerated degradation of organic matter, three physical, chemical treatment in order to maximize to stand in doubt of degradation of organic matter and chroma.
Sewage deal with it? In the sewage treatment process, what kind of equipment to make the sewage to the national emission standards or reuse standards, and run the economy? I am introducing advanced foreign technology to develop and produce a CAF water treatment equipment ZCAF series, mainly used for paper, chemical, printing and dyeing, oil refining and other industrial effluents and urban sewage purification.
Second, the conventional flotation method
Traditionally, two grease traps (gravity sedimentation pond and separator tank), and dissolved air flotation (DAF) systems are used to remove solid contaminants, but they are there is a serious problem in the performance and operation.
Gravity sedimentation pond and separator tank sludge concentration is low, large quantities of sludge, the need for frequent sludge treatment, high treatment costs. If not addressed, the pool of sludge The heavier the more, not only will affect the treatment effect, and in fact, waste water leaving the sedimentation tank and eventually become even worse.
The structure of the vortex CXAF air flotation equipment
Main CXAF CAF equipment flotation box cavitation aerator, the chain scraper system, scum collection and drainage system, the overflow water system, electric control system, with bottles of medicine, storage bottles of medicine, glass rotor flow meter, backflow pipe, circular desk, dosing pump.
The device cabinet is the overall steel structure, but also by my company to provide the cabinet drawings, user self-built concrete structure by our technical staff on-site guidance to install. Suggests that when the stand-alone treated water to more than 320m3 / h, the box of reinforced concrete structures.

Vortex CXAF air flotation equipment works
Pollutants in wastewater into dissolved organic matter and non-soluble substances (ie the SS), dissolved organic matter under certain conditions, can be transformed into a non-solution solution of substances, one of the methods of sewage treatment is the addition of coagulants and flocculation agent to convey most of the dissolved organic matter into a non-soluble substances, and then all or most of the non-solution solution of substance (SS) removal of purification in order to achieve the purpose of sewage, and removal of the SS, the main method is the use of flotation approach.
CXAF is generated by air flotation process. Cavitation aerators microbubbles injected directly into the sewage without the need to advance the dissolved air, and then scattered gas through cast stainless steel impeller to "micro-bubbles evenly distributed in the sewage, so no plugging problems, the equipment does not require pressure vessels, air compressors and circulating pumps, auxiliary equipment.
First of untreated sewage into the aeration inflatable section, "microbubbles" fully mixed "micro bubbles" in the rising process, the suspended solids to the surface. The mud scraper movement along the surface, suspended solids to scrape a metal plate tilted, and then push it into the sludge discharge pipe. Sludge discharge pipe, the level of the propeller will be collected by the sludge into the sludge collector, thrusters and mud scraper driven by a motor. After the purification of sewage before discharge through the inclined plate below the overflow tank, overflow tank is used to control the flotation tank water level, to ensure that the tank of the liquid will not flow into the sludge discharge pipe.
An open return pipe from the aeration section extending along the bottom of the flotation slot. Produce micro-bubbles in the cavitation aeration opportunity to form a negative pressure zone in the drain tube in the bottom, the negative pressure causes water from the bottom of the pond back to the aeration zone, and then returned to flotation segment, The return pipe back to a one-way valve, into the aeration tank of sewage Buzhi Yu is not treated directly from the return pipe into the flotation slot. The whole process ensures that no traffic, the flotation is still ongoing.
The advantages of the vortex CXAF air flotation equipment
1, the saving investment
With CXAF deal with urban sewage and industrial effluent does not require pressure melting tank, air compressor, circulating pumps and other ancillary equipment. The device to remove the sewage grease, colloidal material, suspended solids, COD and BOD, use it to deal with chemical pulping pulping effluent treatment can significantly reduce the chemical and biological secondary treatment (if using waste paper as raw material, after de-inking and bleaching wastewater generated by other processes without chemical and biological secondary treatment to the discharge standards or reuse) equipment scale, or even eliminates the need for biochemical treatment processes and discharge standards, thus greatly reducing the overall investment costs.
2, low running costs
The device uses the multi-aeration head, according to the different decisions of the treated water aerators number of each aerator power only 2.2KW; scraper and sludge screw propeller driven by a motor, power is 2.2KW. Minimal power consumed by the package of ZCAF CAF equipment, equivalent to only 1/8-1/10 of the traditional dissolved air flotation method, and very little maintenance and manual operation, during normal operation without workers guard.
3, high efficiency
Contrary to the traditional grease traps (gravity sedimentation pond and separator tank) CXAF solid sludge automatically and continuously removed from the wastewater. Removal and storage of the sludge is concentrated, the highest concentration of floating sludge collected by this device can reach about 5%, thus reducing the running costs of sludge treatment.
4, superior performance
The handling capacity of the equipment of CXAF CAF 5-2000 m3 / h. According to customer requirements to design different traffic devices. Amount of water into ZCAF do not need to maintain balance, even if the change in flow rate, the device can also be a normal work under normal circumstances, grease and solids County floating solids (SS) removal of more than 95%. Obviously, grease and suspended solids removal, the COD and BOD load greatly reduced, usually COD removal rate can reach 75-85%.
5, simple operation
CXAF CAF equipment simple structure, high degree of automation, easy operation and maintenance.
6, reduce the odor
CXAF CAF equipment of wastewater treatment is an aerobic process, and the sludge is to be removed in a "fresh" state, and thus the odor of the grease traps (gravity sedimentation pond and separator tank) has been a very a better solution. On the other hand, increasing the possibility of re-use of solid, reducing the handling of trouble. '
7, easy to install
CXAF vortex air flotation equipment for civil works exceptionally low ground, underground or height can be installed, and a very short time-consuming.
8, small footprint
Processing capacity of 5-500 cubic meters / hour CAF equipment installation covers an area of only 2.5 to 90 square meters.
1, the company adhering to the "excellent quality, customer satisfaction," the service concept to provide you with excellent products and perfect service.
2, the company re-contract, Shou credibility. Quality first, the sale of products within one year of the Three Guarantees are indeed quality issues such as unpaid returned.
3 Where to buy our products, the company can send technical personnel to guide installation and commissioning, and to undertake the process style design and equipment installation.
4, to ensure year-round promotions and timely supply all kinds of accessories.
