Problems solved by technology
[0002] In actual production, the lubricating waste liquid generated in the production process of the steel cord factory contains a large amount of metal components, which cannot be directly treated by the sewage treatment plant, and the cost of professional treatment of the lubricating waste liquid is very high, and the lubricating waste liquid cannot be stored. Environmental pollution has caused very serious consequences, so the treatment of the waste lubricant in the steel cord factory has always restricted the large-scale development of the steel cord factory

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0015] A kind of process that utilizes cement plant JT kiln to process waste water waste liquid, such as figure 1 shown, including the following steps:
[0016] a. Fill the waste liquid into the waste liquid tank 1, and use the waste liquid pressure pump 2 below the waste liquid tank 1 to send the waste liquid into the waste liquid metering tank 3;
[0017] b. There is a metering pump 4 under the waste liquid metering tank 3. The metering pump 4 pumps the waste liquid in the waste liquid metering tank 3 into the twin-shaft mixer 5 in the production process of the cement plant JT kiln according to the output of cement raw materials.
[0018] A kind of equipment that utilizes the JT kiln of cement plant to treat waste water and liquid, such as figure 1 As shown, it includes the cement production line equipment of JT kiln, and also includes the waste ...

The invention provides a technology for treating waste water and waste liquid by a JT kiln of a cement mill, comprising the following steps of: a. filling the waste liquid into a waste liquid tank, pumping the waste liquid into a waste liquid metering tank by a waste liquid pressure pump under the water liquid tank; and b. providing metering pump under the waste liquid metering tank, pumping the waste liquid in the waste liquid metering tank into a double shaft mixer in a production technology of the JT kiln of the cement mill based on the output of cement raw by the metering pump. The invention further provides equipment for treating waste water and waste liquid by the JT kiln of the cement mill, wherein the equipment comprises cement production line equipment of the JT kiln, and further comprises the waste liquid tank, the waste liquid pressure pump, the waste liquid metering tank and the metering tank, wherein one end of the metering pump is connected with the double-shaft mixer in the cement production line equipment of the JT kiln. The technology and the equipment provided in the invention have advantages of that: because metallic compounds in a lubrication waste liquid can make melting auxiliary effect for calcining cement clinker, the technology and the equipment is in favor of improving combustibility of raw materials, raises intensity and output of the clinker, implements harmless treatment of the lubrication waste liquid, reduces a treating cost of the lubrication waste liquid, and protects environment.
Description
technical field [0001] The invention relates to the technical field of environmental protection-wastewater and waste liquid treatment, is a technology for advanced treatment of waste water and waste liquid, and in particular relates to a process and equipment for treating waste water and waste liquid by using a JT kiln in a cement plant. Background technique [0002] In actual production, the lubricating waste liquid generated in the production process of the steel cord factory contains a large amount of metal components, which cannot be directly treated by the sewage treatment plant, and the cost of professional treatment of the lubricating waste liquid is very high, and the lubricating waste liquid cannot be stored. Environmental pollution has caused very serious consequences, so the treatment of the lubricating waste liquid in the steel cord factory has always restricted the large-scale development of the steel cord factory.
