Wash cloth straw sewage treatment equipment
The washing linen sewage treatment equipment can be buried below the ground surface, and the ground surface can be used for greening or plaza. Therefore, the equipment has no surface area, no need to build a house, and no heating or insulation.
· SQ sewage treatment equipment is composed of two sets of equipment for the steel structure, using domestic anticorrosive coating for anticorrosion. Acid and alkali resistant gasoline kerosene is resistant to aging and abrasion. After the equipment is generally painted with this coating, the anticorrosive life can reach more than 12 years.
· The AO treatment process in the SQ washing wastewater treatment unit adopts a push-flow oxidation tank, and its treatment effect is better than that of the fully-mixed or two or series-completely mixed oxidation tanks. 会产生污泥，同时在氧化池中采用了新型弹性立体材料，它具有实际比表面积大、微挂膜，脱膜方便，在同样有机负荷条件下，比其他填料对有机物的去除率高。 And it is smaller than the activated sludge tank, has strong applicability to water quality, good impact resistance, and does not produce sludge. At the same time, it uses a new elastic three-dimensional material in the oxidation tank. It has a large actual specific surface area and a micro-hanging film. It is easy to remove the film, and under the same organic load condition, the removal rate of organic matter is higher than other fillers. 。 It can dissolve in the air .
· Since the oxidation tank is used in the AO treatment process, the volume load of the filler is relatively low, and it is slightly in the auto-oxidation stage, so the mud production is small. In addition, the moisture content of the sludge produced in the oxidation pond is much lower than that of the activated sludge pond.
Therefore, the amount of sludge produced by the sewage through the TWZ series of sewage treatment equipment is small, and generally only needs to be discharged once in about 90 days.
Wastewater treatment equipment for washing cloth grass source:
With the continuous improvement of people's living standards, large-scale commercial laundry centers and bathing centers in the city have emerged in large numbers. 水加洗涤剂主洗，第三、第四遍（个别还有第五遍）为清洗脱水，整个洗衣过程用水量很大。 The working process of the laundry center is basically similar. Generally, the first pass is washed with cold water, mainly to remove surface substances such as floating soil, the second pass is washed with hot water and detergent, and the third and fourth passes (individually there are also (Fifth pass) For washing and dewatering, the entire laundry process uses a lot of water.
，磷酸盐进入水体会引起水体的富营养化，表面活性剂进入水体后，会使水生动、植物中毒致死。 Therefore, the washing wastewater contains surfactants, sodium tripolyphosphate, carboxymethyl cellulose, oil stains, dust particles, and various microorganisms. The appearance is turbid. The COD is 300 to 800 mg / l, the pH is 6.5 to 7.5, and the content of suspended matter Higher, generally at 500 ~ 1200mg / l . Phosphate entering the water body will cause eutrophication of the water body. After the surfactant enters the water body, it will cause vivid water and plant poisoning to death. 明；甩干废水量小，水质略好于清洗废水。 Soluble some micro-pollutants in the water; large amount of cleaning wastewater, a small amount of foam, less suspended matter, smaller COD, and more transparent ; small amount of spin-dried wastewater, slightly better water quality than cleaning wastewater.
Characteristics of washing linen sewage treatment equipment:
For laundry centers, the general space is relatively small. We have professionally designed small laundry wastewater treatment equipment with a small footprint. 对其他企业较低。 Generally, the laundry center has a small amount of water and a low profit. We use advanced high-efficiency biochemical technology to ensure compliance and lower investment compared to other enterprises.
Principle of washing cloth straw sewage treatment equipment:
脱稳，再投加PAM使之絮凝沉降；出水自流进入沉淀池，利用重力作用使泥水分离；出水自流进入集水池，收集沉淀池出水；出水经泵提升至HY-BW型一体化污水处理设备，在HY-BW型一体化污 水处理设备内，首先经过水解酸化池，水解酸化池内废水在厌氧菌作用下，大分子有机物被分解成为小分子有机物，提高废水的可生化性，减小后续好氧处理运行负荷；出水自流进入一级接 触氧化池，好氧微生物利用水中的有机污染物为底物进行好氧代谢，使有机物以低能位的无机物稳定下来，达到无害化的过程，其中有机物被摄取之后，一部分被分解、稳定、并为微生物提 供能量，一 The laundry wastewater is collected by the pipe network and enters the sewage treatment system. After the fibers and large floating objects are retained by the grid, the effluent flows into the adjustment tank to balance the water quality of the wastewater. The effluent is pumped to the coagulation reaction tank, and PAC is added to make it. The colloidal phase system of the wastewater is destabilized, and then PAM is added to make it flocculate and settle; the effluent flows into the sedimentation tank to separate the mud and water by gravity; the effluent flows into the catchment pool to collect the effluent from the precipitation tank; the effluent is raised to the HY-BW type by the pump Integrated sewage treatment equipment. In the HY-BW integrated sewage treatment equipment, the hydrolytic acidification tank first passes through the hydrolysis acidification tank. Under the action of anaerobic bacteria, the macromolecular organic matter is decomposed into small molecular organic matter, which improves the wastewater Biochemical, reduce the operation load of subsequent aerobic treatment; the effluent flows freely into the first-stage contact oxidation pond, and aerobic microorganisms use organic pollutants in the water as a substrate for aerobic metabolism, so that the organic substances are stabilized by low-energy-level inorganic substances. The process of achieving harmlessness, in which after the organic matter is ingested, a part is decomposed, stabilized, and provides energy for microorganisms . 放。 Part of it synthesizes new cellular material, that is, biological sludge, which needs to be drained regularly; the effluent flows into the secondary contact oxidation pond to further reduce the organic matter in the wastewater; the effluent flows into the sedimentation tank, where the sedimentation treatment is performed, and the mud and water are separated; the effluent reaches the standard discharge put. The settled sludge is partially returned by the sludge pump to the inside of the HY-BW integrated sewage treatment equipment. The remaining sludge is driven into the sludge drying pond by the sludge pump, and is regularly pumped out for external treatment.
