一廢水來源及水質

某制藥廠廢水主要是生產青霉素所產生的高濃度有機廢水

 該類廢水的主要特點是有機物濃度高，成分復雜含有石油類、胺類、酸類、破乳劑等污染物。除此之外水中含有難以解釋的大分子苯環物質和濃度很高的SO2﹣4及其鹽類，這些物質將嚴重抑制微生物對水中有機物的生物降解。因此，正確選用合適該類廢水處理工藝是處理成功與否的關鍵。

A wastewater source and water quality

Wastewater from a pharmaceutical factory is mainly a high concentration of organic wastewater produced by the production of penicillin

The main characteristic of this kind of waste water is the high concentration of organic material, which contains oil, amine, acid and demulsifier. In addition, the water contains unexplainable large molecular benzene ring material and the high concentration of SO2, 4 and its salts, which will severely inhibit microbial biodegradation of organic matter in water. Therefore, proper selection of appropriate wastewater treatment technology is the key to success.

二  處理工藝流程及說明

調節池主要用于調節來水的水量和水質的不均勻性。調節時間按8h設計

反應池采用6格穿孔旋流反應形式，孔口流速由1.0m/s逐格遞減至0.15m/s。反應時間20min左右。

采用斜板沉淀池。斜板間距80mm，表面水力負荷2.1m3/(㎡?h).

水解酸化工藝主要用來使難易降解的苯環物質、大分子有機物開環斷鏈，變為易于生物降解的小分子物質，對改善廢水的可生化性，有利于后續好氧生物降解。

本工程設計水解酸化時間為15h,池內設置彈性填料和水下曝氣裝置。

Process and descrtption of the process

The regulating pool is mainly used to regulate the water quantity and the inhomogeneity of water quality. Adjust the time according to 8h design

The reaction pool was in the form of 6 - hole swirl flow, and the flow velocity was reduced by 1.0m/s to 0.15m/s. The reaction time is about 20min.

Use inclined plate sedimentation tank. Inclined plate spacing is 80 mm, the surface hydraulic load of 2.1 m after / ㎡ (h).

Hydrolysis acidification process is mainly used to make easy degradation of benzene ring material, macromolecule organic matter open loop chain scission, small molecules into easily biodegradable material, to improve the wastewater biological sex, is advantageous to the subsequent aerobic biodegradation.

The hydrolysis time of this engineering design is 15h, with elastic packing and underwater aeration device in the tank.

在SBR反應池進水端部設置生物選擇器（又稱與反應區），使回流的活性污泥和原水中的有機物在此處達到充分混合和吸附，使回流的大量微生物得以淘劣選優、培養和馴化，誘導出活性很強的微生物群體，并能抑制絲狀菌的生長和繁殖，對后續好氧反應控制污泥膨脹具有重要作用。改反應過程一般45min~60min即可完成。

In SBR reaction pool water end set biological selector (also called and reaction zone), make the backflow activated sludge and organic matter in raw water here to fully mix and adsorption, the flow of a large number of microbes to losers selection, cultivation and domestication, induction of active microbial community, and can inhibit the growth of filamentous bacteria and reproduction, on subsequent aerobic sludge bulking control plays an important role. The reaction process is usually 45min~ 60min.

SBR工藝又稱序批式間歇活性污泥法，是最近幾年國內興起的集生物降解、沉淀、排水、排泥等功能于一體的污水生化處理工藝。在運行過程中，采用PLC可編程序控制器，按時間和液位實現全過程自動控制。

本工程設置3座SBR反應池，每池運行周期12h。其中充水期4h，反應期8h（其中包括充水期3.5h），沉淀期1.5h，排水期1.5h，閑置期0.5h，MLSS為3500mg/L.

The SBR process is also called sequential batch intermittent activated sludge method, which is a sewage and biochemical treatment process which has been developed in recent years in China, which integrates biological degradation, precipitation, drainage and sludge discharge. In the process of operation, PLC programmable controller is adopted to realize automatic control of the whole process by time and liquid level.

This project sets up three SBR reaction pools, each running cycle 12h. Among them, the water filling period was 4h, the reaction period was 8h (including the filling period of 3.5 h), the precipitation period was 1.5h, the drainage period was 1.5h, the idle period was 0.5 h, and the MLSS was 3500mg/L.

本工程污泥分為化學污泥和剩余活性污泥兩部分。前者經初沉淀池排出，直接進入污泥脫水系統；后者在每座SBR池里內置1個8m×5m×8m的濃縮池，濃縮后的污泥經提升泵回流至生物選擇器和水解酸化池，剩余污泥與化學污泥一起儲存于污泥池內，進行脫水外運。污泥脫水設置5臺帶式壓榨過濾機，帶寬2m.

The sludge is divided into two parts: chemical sludge and residual activated sludge. The former is discharged through the initial sedimentation tank and directly into the sludge dewatering system; The latter in each SBR pool built a 8 m x 5 m x 8 m concentrated tank, after enrichment of the sludge by lift pump back into biological selector and hydrolysis acidification pool, excess sludge storage with chemical sludge in sludge pool, sinotrans for dehydration. The sludge dewatering sets 5 belt type press filter, the bandwidth is 2m.

工程運行效果

通過三個多月的效果和監測，處理效果顯著，運轉穩定。其中在混合沉淀工藝中實際COD去除率為40%~50%，BOD5去除率為30%~50%。SS去除率為60%~70%；在水解酸化工藝中，COD去除率為25%~35%，BOD5去除率為20%~25%.

Engineering operation effect

Through more than three months of effect and monitoring, the treatment effect is remarkable, the operation is stable. In the mixed precipitation process, the actual COD removal rate was 40%~ 50%, and the removal rate of BOD5 was 30%~ 50%. The removal rate of SS is 60%~ 70%; In the hydrolytic acidification process, COD removal rate is 25%~ 35%, and BOD5 removal rate is 20%~25%.
