冲洗水

In order to improve the problems from HDT-55 truntable filters, measures are taken as follows:cloth water and distributing trough are rotated clock-wise at 10～15°, athodyd combustion chamber enlarged, filter cloth washing nozzle, ring-shaped pipe material improved.

为了改进HDT-55转台过滤机使用中暴露出的布料布水槽角度不合理、栈桥及支架腐蚀严重、滤布冲洗水喷头易堵、钢衬胶真空环形管易起泡等问题，采取了如下措施：将布水、布料槽顺时针转10～15°，增加吸气室空间，改进滤布冲洗喷头总成，改进环形管材质等。

The method comprises the following steps: according to the raw water quality, the change of the number of bacteria inside the sedimentation tank and the water quality of the backflush yielding water, the backflush yielding water in the sedimentation tank is collected and deposited in a backflush phase of a working period; supernatant fluid containing mass active bacteria and soluble nutrient elements reflow to the sedimentation tank; total or partial sediment containing soluble nutrient elements in an underlayer reflow to the sedimentation tank and is reutilized by mass microorganisms in the sedimentation tank, thereby replenishing the nutrient substrate needed for microorganism growth, proliferation and metabolism under the condition of the low nutrition substrate, and maintaining the ecological stability in the sedimentation tank.

该方法根据原水水质和生物滤池内部细菌数量的变化以及反冲洗出水的水质，将生物滤池工作周期中反冲洗阶段的反冲洗出水收集并沉淀，将其含有大量活性细菌和溶解性营养元素的上清液回流至生物滤池，下层含有不溶性营养物质的沉淀全部或部分回流至生物滤池，被生物滤池当中的大量存在的微生物重新利用，从而补充在低营养基质条件下，微生物生长、增殖和新陈代谢所必需的营养基质，维持生物滤池当中的生态稳定。

A process for treating the sludge generated by alumina sewage treating system incldues such steps as pumping the alumina sewage in sand depositing pool then in depositing pool, mixing the bottom sludge, the sewage from sand-water separator, and the regenerated water from filter to obtain backflush water, heating in desilicating heater, washing the secondary red mud to recover Na2O and Al2O3, anjd returning the washing liquid containing Na2O and Al2O3 back to the flow of production of alumina.

本发明公开了一种氧化铝废水处理系统的污泥处置新工艺，它将氧化铝废水先进入沉砂池中进行沉砂处理后才进入沉淀池中，将虹吸泥机从沉淀池中吸出的底流污泥和砂水分离器分离出的污水以及将部分经过滤器过滤后所得的再生水作为反冲洗水一起通过污泥泵送到脱硅加热器中加热得污泥热水，然后将污泥热水用于二赤泥洗涤沉降，以回收赤泥附着的Na2O和Al2O3，将洗涤赤泥后含有Na2O和Al2O3的洗液送到氧化铝生产流程中重新使用。

After this, it should be rinsed with warm water and air dried.

在这之后，应该用温水冲洗水和空气干燥。

During the accident, the main steam pressure drops rapidly, the current and outlet temperature of pulverizer become abnormal.

明确了主蒸汽压力快速下降和磨煤机电流、出口温度异常变化是该类型事故的主要现象，指出石子煤冲洗系统冲洗水采用母管制和系统相关阀门工作环境恶劣造成阀门易磨损卡涩是导致磨煤机进水事故发生的根本原因。

The value of pH in outlet water was higher than grade- I of Emission Standard (6-9), so this water were not permitted to emit. But a certain quantity of the water could be reused in the working procedure of hydrolyzing calcareousness, and the remains could be reused as washing water or emitted directly after neutralization by acid.

出水的pH值高于一级排放标准的6～9，不能直接排放，但部分出水可回用于石灰消解工序，其余出水经加酸调节后可作为工艺冲洗水或外排。

After this, it should be rinsed with warm water and air dried.

在这之后，应该用温水冲洗水和空气乾燥。
