2) Back pouring of cement mortar
浆液回灌
3) leachate recirculation
渗滤液回灌

When the operation mode was changed from anaerobic mode to semi-aerobic mode in the 710th day,the COD concentration of simulated bioreactor landfill column D1(leachate recirculation once everyday) and D4(leachate recir.
模拟厌氧型生物反应器填埋场垃圾柱稳定后期改为按准好氧方式运行,能加快渗滤液COD和氨氮浓度的衰减速率,而较高的渗滤液回灌频率更能强化这一优势。

The characteristics and the mechanism of nitrogen removal in a leachate recirculation biological reactor landfill system as well as in a nitrogen removal bioreactor landfill system have been studied by laboratory simulation experiments.
虽然相对于传统的填埋场而言,渗滤液回灌型生物反应器填埋场系统有利于促进填埋层微生物的生长,但并不能促进垃圾有机污染物的彻底厌氧降解,甚至会导致高浓度氨氮的积累而增加场外处理难度;为此,通过实验室动态模拟试验,进行了渗滤液回灌型生物反应器填埋场系统和脱氮型生物反应器填埋场系统对填埋垃圾的脱氮性能及脱氮机理的初步研究。

It is found that the leachate flow modeling which is set up on the basis of isotropic and homogeneous hypothesis of waste(property) can not meet the needs of designing and operating the leachate recirculation system in bioreactor landfill.
本文对填埋场渗滤液产生和运移的水力学特性的研究成果进行了总结,建立在填埋垃圾均质各向同性假设基础上的渗滤液运移模型不能满足日后生物反应器填埋场渗滤液回灌系统的设计和操作运行需要,基于填埋垃圾非均质各向异性的填埋场水力学特性将是今后研究的重点。
4) Liquid oxygen returning valve
液氧回灌阀
5) Concentrated liquid recharge

Small volume and high precision canning technique used in liquid canning production line and new structure without unilateral valve were introduced in this article.
介绍液体灌装联动线小容量高精度灌装技术及取消单向阀新型结构。
补充资料：地下水回灌
简称“回灌”、“人工引渗”。降雨径流、河流来水、灌溉退水、经处理后的城市生活污水和工业废水等，通过地面入渗或水井注入对地下水源的人工补给工作。可控制地面沉降，防止海水入侵含水层，改善地下水水质，调节地下水温，保持地热水、天然气和石油地层的压力等。
