摘要： The present invention relates to a method of treating alkaline waste water originating from washing spent oil which has undergone an alkaline treatment with water and which contains organic material. This method can produce water which can be discharged into conventional industrial water treatment facilities or which can be used directly as a base for preparing fertilizers or for preparing an agent for preventing ice formation on road surfaces.

摘要： An agricultural lagoon and manure treatment system to maintain the lagoon and lagoon water in a more useable condition through the use of sulfuric acid to treat the system components of confined animal feeding operations, including the lagoon. Relatively pure sulfuric acid is controllably released from a storage tank, through an injection pump and into the fluid line transporting recirculation water from the lagoon to flush livestock alleys and maintain the pH of the lagoon fluid at approximately 6.5 to 7.0. A sulfuric acid injection pump injects the sulfuric acid into the fluid line through a fluid injector at a rate necessary to maintain the lagoon fluid in the desired pH range. The fluid injector injects the acid at or near the center of the water stream in the fluid line. The rate of sulfuric acid injected is determined by checking the pH of the water downstream of the injection point, such as at the flush alleys, with a hand-held, portable pH meter. Alternatively, sulfuric acid can be added to the lagoon at the point where manure enters the lagoon to directly treat the lagoon or the acid can be added to a fluid discharge line that is connected to the lagoon to deliver lagoon water to an irrigation system for irrigating agricultural crops.
摘要翻译：一个农业泻湖和粪便处理系统，通过使用硫酸来治理包括泻湖在内的动物喂养操作的系统组成部分，将泻湖和泻湖水保持在更可用的状态。相对纯的硫酸可从储罐中通过注射泵可靠地释放，并进入从泻湖运送再循环水的流体管线，以冲洗牲畜小巷，并将泻湖液体的pH值保持在6.5至7.0左右。硫酸注射泵通过流体注射器将硫酸注入流体管线中，其速率必须将泻湖液体保持在所需的pH范围内。流体注射器在流体管线中的水流中心处或附近注入酸。通过用手持式便携式pH计检查注射点下游的水，例如冲洗小巷，测定注入硫酸的速率。或者，可以在粪便进入泻湖的地方将硫酸加入到泻湖中直接处理泻湖，或者可以将酸添加到连接到泻湖的流体排放管线上，以将泻湖水输送到灌溉系统进行灌溉农作物

摘要： A process for treating alkaline solutions obtained from lithographic printing plate processing comprises admixing at least one alkaline solution and at least one acidic solution in the presence of at least one aqueous solution to obtain a discharge solution having a pH in the range of about 5.0 to 11.5. Another process for treating alkaline solutions obtained from lithographic printing plate processing comprises admixing at least one alkaline solution and at least one aqueous waste water solution to obtain an aqueous alkaline solution, and admixing the resultant aqueous alkaline solution with at least one acidic solution to obtain a discharge solution having a pH in the range of about 5.0 to 11.5, and to control systems for such processes, and methods of controlling such processes. The alkaline solution has a pH greater than 7.0, preferably greater than about 12.5, and the acidic solution has a pH less than 7.0, preferably less than about 2.5. The alkaline, acidic and aqueous solutions are admixed in volume ratios in the range of about 1 part alkaline: 0.2-4.0 parts acidic: ≧50 parts aqueous. The invention advantageously avoids the formation of unacceptable gels, sludge, or precipitate which typically occurs if the acidic solution is used to neutralize the alkaline solution.
