河南天通废水处理设施淀粉污水处理设备质量保障

河南商丘淀粉污水处理设备:

淀粉是我们都非常常见的一种东西,在我们的日常生活中,它的利用率很高,淀粉是日常饮食中常用的辅助食品原料,也大量用于纺织、造纸、医药、发酵、铸造、胶粘、化工、机械及钻井等行业。

生产淀粉的原料很多,有玉米淀粉、地瓜淀粉、土豆淀粉等。淀粉生产过程中产生的废水量很大,大约生产1吨淀粉需要排放10~20m³的废水。淀粉废水含有大量淀粉、蛋白质、糖类、脂肪等有机物。淀粉生产由原料处理、浸泡、粉碎、过筛、分离淀粉、洗涤、干燥等几个主要工序组成。淀粉废水主要有两种:一为高浓度有机工艺废水, 具有四高一低的特点, 即CODCr高( 8 000~ 15 000 mg /L)、悬浮固体( SS)高( 1 000~ 3 000mg /L)、总氮值高( 240~ 540mg /L)、磷酸盐浓度高(以P计, 约15~ 130 mg /L) , 一低为pH 值低( 4. 2~ 5 ); 二是中等浓度有机废水, CODC r值在2 000~ 3 500 mg /L, 氨氮和磷酸盐浓度均不高, 分别为20 mg /L和14~ 32mg /L。

目前处理淀粉废水的常用方法有沉淀分离法、化学絮凝法、曝气法、生物处理法。生物处理法包括活性污泥法、厌氧生物法、生物膜法、生物塘法。

根据淀粉类废水特点及处理出水要求,该废水处理工艺宜采用混凝沉淀设备+两级气浮处理+生化处理工艺。废水中COD较高,因此该废水采取气浮加药处理,尽量降低进入生物处理构筑物的悬浮物含量,再进行生化处理,确保生化处理的正常运行。淀粉污水处理流程去除大部分悬浮物和泥砂后进入调节池,经调节池调节水质水量后,并后续处理设施的正常运行。经过调节池的水经泵提升至混凝沉淀设备中进行预处理,处理后的水进平流式溶气气浮设备,进一步处理,处理后的水再次进入下一个溶气气浮设备中进行处理,去除水中悬浮物(ss),去除率达90%以上,然后出水进入一体化污水处理设备,一体化污水处理设备由(厌氧池、好氧池、二沉池、污泥池组成),污水在水厌氧、好氧池处理,通过厌氧菌将大分子有机物转化成低分子有机物进行生化反应,生物接触氧化池在充足供氧的条件下,好氧微生物群以污水中的有机物为营养,通过分解吸收有机物来进行自身的新陈代谢活动,从而达到去除污水中有机物的效果。

Henan Shangqiu starch sewage treatment equipment:

Starch is a kind of thing we are very common, in our daily life, its utilization rate is very high, the starch is commonly used auxiliary raw food diet, are widely used for textile, papermaking, medicine, fermentation, casting, adhesive, chemical, machinery and drilling industry.

There are many raw materials for producing starch, such as corn starch, sweet potato starch, potato starch and so on. The amount of wastewater generated in the production process of large starch wastewater, emissions about 1 tons of starch production of fand 10~20m. Starch wastewater contains a large number of organic substances such as starch, protein, sugar, fat and so on. The production of starch is composed of several main processes, such as raw material treatment, soaking, crushing, screening, separating starch, washing and drying. There are two main types: one is the starch wastewater of high concentration organic wastewater process, has the characteristics of four high and one low, namely, high CODCr (8 000~ 15000 mg /L), suspended solids (SS) and high (1 000~ 3 000mg /L), total nitrogen (240~ 540mg /L) high value, high concentration of phosphate (P about 130 meter, 15~ mg /L), a low pH value is low (4. 2~ 5); two is a medium concentration organic wastewater, CODC R 2 000~ 3500 mg value in /L, ammonia nitrogen and phosphate concentration were not high, were 20 mg /L and 14~ 32mg /L.

At present, the commonly used methods for treating starch wastewater include precipitation separation, chemical flocculation, aeration and biological treatment. Biological treatment methods include activated sludge process, anaerobic biological method, biofilm method and biological pond method.

According to the characteristics of the starch wastewater and the requirements for treating the effluent, the coagulation sedimentation equipment + two stage air flotation treatment + biochemical treatment process should be adopted in the wastewater treatment process. The COD in wastewater is high, so the wastewater is treated by air flotation and dosing, so as to minimize the content of suspended solids entering biological treatment structures, and then carry out biochemical treatment to ensure the normal operation of biochemical treatment. After removing most of suspended solids and sludge, the starch wastewater treatment process enters the regulating pool, and then adjusts the water quality and quantity of water through the regulating pool, and ensures the normal operation of the subsequent treatment facilities. After the water pump to enhance regulation tank pretreatment coagulation device, the treated water into the advection type dissolved air flotation equipment, further processing, the treated water again into a dissolved air flotation equipment for processing, the removal of suspended solids in water (SS), the removal rate of more than 90%. Then the effluent into the integrated wastewater treatment equipment, integrated wastewater treatment equipment (by anaerobic pond and aerobic pond, two sink the pond, sludge pool), sewage treatment in water of anaerobic and aerobic tank, anaerobic bacteria by macromolecular organic matter into low molecular organic compounds in biochemical reactions, biological contact oxidation pool in full under the oxygen condition, aerobic microorganisms to organic wastewater for nutrition, to conduct their own activities through the decomposition of organic matter The new supersedes the old. absorption, so as to achieve the effect of removal of organic matter in sewage.
