气候炎热和降雨不足：
马来西亚地处热带地区，气候炎热潮湿，但由于其地理位置和海洋环流的影响，降雨分布不均。在一些地区，降雨量很少，甚至没有降雨，导致水资源短缺。
人口增长和经济发展：
随着人口的增加和经济的发展，对水资源的需求也越来越大。尤其是城市化进程加快，城市居民的生活和工业用水需求大幅增加，使得水资源更加紧缺。
水资源管理不当：
马来西亚政府在水资源管理方面存在一些问题，如水资源分配不合理、过度开采地下水等。此外，一些地区的水资源开发利用不当，导致浪费和污染等问题，进一步加剧了水资源短缺的问题。
自然灾害：
马来西亚经常受到自然灾害的影响，如洪水、干旱等，这些灾害会给水资源带来很大的损失，加剧了水资源的短缺问题。
由此可见，马来西亚地区的水资源也比较珍贵，生活用水紧缺，需要应用一体化污水处理设备来处理生活污水。

该设备正是出口马来西亚污水处理设备，由中侨启迪生产制造安装售后为一体的一体化污水处理设备。
根据业主要求，本工程中考虑采用先进的生物（AO+消毒）法。
一体化A/O是Anoxic/Oxic的缩写，它的优越性是除了使有机污染物得到降解之外，还具有一定的脱氮除磷功能，是将厌氧水解技术用为活性污泥的前处理，所以A/O法是改进的活性污泥法。A/O工艺将前段缺氧段和后段好氧段串联在一起，A段DO不大于0.2mg/L，O段DO=2～4mg/L。在缺氧段异养菌将污水中的淀粉、纤维、碳水化合物等悬浮污染物和可溶性有机物水解为有机酸，使大分子有机物分解为小分子有机物，不溶性的有机物转化成可溶性有机物，当这些经缺氧水解的产物进入好氧池进行好氧处理时，可提高污水的可生化性及氧的效率；在缺氧段，异养菌将蛋白质、脂肪等污染物进行氨化（有机链上的N或氨基酸中的氨基）游离出氨（NH3、NH4+），在充足供氧条件下，自养菌的硝化作用将NH3-N（NH4+）氧化为NO3-，通过回流控制返回至A池，在缺氧条件下，异氧菌的反硝化作用将NO3-还原为分子态氮（N2）完成C、N、O。

在生态中，根据以上对生物脱氮基本流程的叙述，结合中侨启迪多年的焦化废水脱氮的经验，我们总结出(A/O)生物脱氮流程具有以下优点：
（1）效率高。该工艺对废水中的有机物，氨氮等均有较高的去除效果。当总停留时间大于54h，经生物脱氮后的出水再经过混凝沉淀，可将COD值降至100mg/L以下，其他指标也达到排放标准，总氮去除率70%以上。
（2）流程简单，投资省，操作费用低。该工艺是以废水中的有机物作为反硝化的碳源，故不需要再另加甲醇等昂贵的碳源。尤其，在蒸氨塔设置有脱固定氨的装置后，碳氮比有所提高，在反硝化过程中产生的碱度相应地降低了硝化过程需要的碱耗。
（3）缺氧反硝化过程对污染物具有较高的降解效率。如COD、BOD5和SCN-在缺氧段中去除率在67%、38%、59%，酚和有机物的去除率分别为62%和36%，故反硝化反应是最为经济的节能型降解过程。
（4）容积负荷高。由于硝化阶段采用了强化生化，反硝化阶段又采用了高浓度污泥的膜技术，有效地提高了硝化及反硝化的污泥浓度。
（5）缺氧/好氧工艺的耐负荷冲击能力强。当进水水质波动较大或污染物浓度较高时，本工艺均能维持正常运行，故操作管理也很简单。通过以上流程的比较，不难看出，生物脱氮工艺本身就是脱氮的同时，也降解酚、氰、COD等有机物。结合水量、水质特点，我们推荐采用缺氧/好氧(A/O)的生物脱氮(内循环) 工艺流程，使污水处理装置不但能达到脱氮的要求，而且其它指标也达到排放标准。
出口马来西亚一体化污水处理设备
Malaysia (Malaysia) is located in Southeast Asia, consisting of Malaya in the south of the Malay Peninsula and Sarawak and Sabah in the north of Kalimantan Island. It borders Thailand in the north, Singapore across the Johor Strait in the south, the South China Sea in the east and the Strait of Malacca in the west.
Hot climate and insufficient rainfall:
Malaysia is located in tropical regions with a hot and humid climate, but rainfall is evenly distributed due to its geographical location and the influence of ocean circulation. In some areas, little or even no rainfall, leading to water shortages.
Population growth and economic development:
With the increase of population and economy development, the demand for water resources is also increasing. In particular, with the acceleration of the urbanization process, the living and industrial water demand of urban residents has increased greatly, making the water resources more scarce.
Improper management of water resources:
The Malaysian government has some problems in water resources management, such as the unreasonable distribution of water resources and the over-exploitation of groundwater. In addition, the improper development and utilization of water resources in some areas leads to problems such as waste and pollution, further exacerbating the problem of water shortage.
natural calamities:
Malaysia is often affected by natural disasters, such as floods and droughts, which will bring great losses to water resources and aggravate the shortage of water resources.
It can be seen that water resources in Malaysia are also precious and domestic water is short, so integrated sewage treatment equipment is needed to treat domestic sewage.
The equipment is an integrated sewage treatment equipment exported to Malaysia, which integrated sewage treatment equipment.
According to the Owner, the advanced biological (AO + disinfection) method is considered in the Project.
Integrated A / O is the abbreviation of Anoxic / Exit. Its advantage is that in addition to grading organic pollutants, it also has A certain function of nitrogen and phosphorus removal. It is to use anaerobic hydrolysis technology as the pretreatment of activated sludge, so A / O method is an improved activated sludge method. The A / O process connects the anterior anoxic segment and the posterior aerobic segment in series, A segment DO is not greater than 0.2 mg/L, and O segment DO = 2 ~ 4 mg/L. In the heterotrophic bacteria, starch, fibers, carbohydrates in sewage and soluble organic matter into organic acids, The decomposition of macromolecular organic matter into small molecular organic matter, Insoluble organic matter is converted into soluble organic matter, When these products that undergo hypoxic hydrolysis move into the aerobic pool for aerobic treatment, Can improve the bioavailability of sewage and oxygen efficiency; In the anoxic segment, Heterotrophic bacteria aminate protein, fat and other pollutants (N or amino acids in the organic chain) to free ammonia (NH3, NH4 +), Under adequate oxygen supply conditions, Nitrification of autotrophic bacteria oxidizes NH3-N (NH4 +) to NO3-, Return to pool A by reflux control, Under the hypoxic conditions, The denitrification of heterobiotics reduces NO3-to molecular nitrogen (N2) for C, N, and O. In ecology, according to the above description of the basic process of biological nitrogen removal, combined with the experience of coking wastewater denitrification for many years, we conclude that (A / O) biological nitrogen removal process has the following advantages:
(1) High efficiency. This process has a high removal effect on the organic matter and ammonia nitrogen in the wastewater. When the total residence time is more than 54h, the effluent water after biological nitrogen removal can undergo coagulation precipitation, reducing the COD value to less than 100 mg/L. Other indicators also meet the emission standard, and the total nitrogen removal rate is more than 70%.
(2) Simple process, less investment, low operation cost. This process takes the organic matter in the wastewater as the carbon source of denitrification, so there is no need to add methanol and other expensive carbon sources. In particular, after the carbon-nitrogen ratio is set in the ammonia tower, the ratio is increased, and the alkalinity produced in the denitrification process correspondingly reduces the alkali consumption required by the nitrification process.
(3) The hypoxia-denitrification process has a high degradation efficiency for pollutants. For example, the removal rate of COD, BOD 5 and SCN-in the hypoxic section is 67%, 38% and 59%, and the removal rate of phenol and organic matter is 62% and 36% respectively, so denitrification is the most economical energy-saving degradation process.
(4) High volume load. Because the nitrification stage adopts enhanced biochemistry, and the high concentration of sludge membrane technology is adopted in the denitrification stage, effectively improve the sludge concentration of nitrification and denitrification sludge.
(5) The hypoxia / aerobic process has strong load resistance and impact resistance. When the incoming water quality fluctuates greatly or the pollutant concentration is high, the process can maintain the normal operation, so the operation and management is also very simple. Through the comparison of the above processes, it is not difficult to see that the biological nitrogen removal process itself is denitrification, but also degrade phenol, cyanide, COD and other organic compounds. Combined with the characteristics of water quantity and water quality, we recommend the use of hypoxia / aerobic (A / O) biological nitrogen removal (internal cycle) process, so that the sewage treatment device can not only meet the requirements of nitrogen removal, but also other indicators to meet the emission standards.
