污水處理的每項工藝技術(shù)都有其優(yōu)點、特點、適用條件和不足之處，不可能以一種工藝代替其他一切工藝，也不宜離開當(dāng)?shù)氐木唧w條件和我國國情。同樣的工藝，在不同的進(jìn)水和出水條件下，取用不同的設(shè)計參數(shù)，設(shè)備的選型并不是一成不變的。那么選擇生物脫硫污水處理工藝有哪些原則呢？
Each process and technology of sewage treatment has its advantages, characteristics, applicable conditions and shortcomings. It is impossible to replace all other processes with one process, and it is not appropriate to leave the specific local conditions and China's national conditions. For the same process, under different conditions of inlet and outlet water and different design parameters, the selection of equipment is not invariable. So what are the principles of biological desulfurization wastewater treatment process?
1、技術(shù)合理。技術(shù)而成熟，對水質(zhì)變化適應(yīng)性強(qiáng)，因為項目所在地污水量晝夜變化大，從而造成水質(zhì)波動較大，處理工藝應(yīng)具有較強(qiáng)的適應(yīng)沖擊負(fù)荷的能力;出水達(dá)標(biāo)且穩(wěn)定性高，滿足受納水體對排水水質(zhì)要求，污泥易于處理。選擇的處理工藝應(yīng)確保出水水質(zhì)滿足我國和地方現(xiàn)行的有關(guān)規(guī)定，符合環(huán)境影響評價報告的要求。
1. The technology is reasonable. The technology is advanced and mature, and has strong adaptability to water quality changes. Because the sewage volume in the project site changes greatly day and night, resulting in large fluctuation of water quality, the treatment process should have strong ability to adapt to the impact load; the effluent meets the standard and has high stability, meeting the requirements of receiving water body for drainage water quality, and sludge is easy to be treated. The selected treatment process should ensure that the effluent quality can meet the current national and local regulations and meet the requirements of environmental impact assessment report.
2、經(jīng)濟(jì)節(jié)能?；ㄍ顿Y和運行費用低，占地少。
2. Economy and energy saving. Infrastructure investment and operation costs are low, and land occupation is small.
3、易于管理。工藝流程須簡捷流暢，以降低工程造價及運行費用，操作管理方便，設(shè)備可靠。要求管理簡單、運行穩(wěn)定、維修方便。這對于小城市尤為重要，因為小城市往往技術(shù)力量比較薄弱。
3. Easy to manage. The technological process should be simple and smooth to reduce the project cost and operation cost, convenient operation and management, and reliable equipment. It requires simple management, stable operation and convenient maintenance. This is particularly important for small cities, which are often weak in technology.
4、重視環(huán)境。總平面布置力求流程順暢，合理緊湊，減少占地，土方平衡并考慮防洪、預(yù)留遠(yuǎn)期處理用地。廠區(qū)平面布置與周圍環(huán)境相協(xié)調(diào)，注意廠內(nèi)噪聲控制和臭氣的治理，綠化、道路與分期建設(shè)結(jié)合好。
4. Pay attention to the environment. The general layout should strive for smooth flow, reasonable and compact process, reduce land occupation, balance earthwork, and consider flood control and reserve land for long-term treatment. The layout of the plant area should be coordinated with the surrounding environment. Attention should be paid to the noise control and odor control in the plant. The greening, roads and phased construction should be well combined.
5、采用以生物方法為主體的處理工藝，在生物處理構(gòu)筑物中，去除大部分的污染物。
5. Most of the pollutants in the biological treatment structures are removed by the biological treatment process.
6、除磷、脫氮效果好，運行穩(wěn)定。
6. The effect of phosphorus and nitrogen removal is good and the operation is stable.
以上就是對選擇污水處理工藝有哪些原則的介紹了，選擇污水處理工藝應(yīng)根據(jù)原水水質(zhì)、出水要求、污水廠規(guī)模，污泥處置方法及當(dāng)?shù)販囟?、工程地質(zhì)、征地費用、電價等因素作慎重考慮。希望上述內(nèi)容對大家有所幫助，如想了解更多內(nèi)容請點擊官網(wǎng)：

The above is the introduction of the principles for the selection of sewage treatment process. The selection of sewage treatment process should be carefully considered according to the raw water quality, effluent requirements, sewage plant scale, sludge disposal method, local temperature, engineering geology, land acquisition cost, electricity price and other factors.
