Problems solved by technology

In order to achieve the ideal effect of the stone surface in the production process, some enterprises use a large amount of domestic water, which has caused a serious waste of water resources on the earth; some enterprises have begun to treat and recycle waste water in order to save domestic water.
[0003] At present, the wastewater treatment methods frequently used in the stone industry, such as digging multiple pools to filter and settle one by one, using multiple iron tanks to settle one by one, and using iron towers to treat wastewater, have no measures and methods to automatically detect and adjust water quality. Therefore, The so-called clear water produced will cause serious damage to the surface of the machine and stone, and the transportation of the produced slurry and powder cake will cause serious damage to the environment

Abstract

A method for adjusting stone machining wastewater quality comprises the following steps: providing a stone machining wastewater quality adjusting system which comprises a water quality automatic checkout device and a micro computer water quality adjusting device; arranging a deposition liquid; arranging a water quality adjusting liquid; manually setting the concentration of the water quality adjusting liquid and the deposition liquid; testing the flow, the concentration and the pH value of the wastewater in a ditch by the micro computer water quality automatic checkout device; transmitting the tested flow, concentration and pH value of the wastewater to the micro computer water quality adjusting device; and according to the set concentrations of the water quality adjusting liquid and the deposition liquid, controlling the automatic addition of the deposition liquid and / or the water quality adjusting liquid into the wastewater by the PLC automatic control system in the micro computer water quality adjusting device after the PLC automatic control system accepts the testing values of the flow, the concentration and the pH value of the wastewater. The method is capable of accurately controlling addition of the deposition liquid and the water quality adjusting liquid into the wastewater, and helps to guarantee that the wastewater is neutral, so that the water quality reaches production requirement, and has no corrosion generated on stone surfaces, so that the surface gloss of stones reaches production requirements; and also the method helps to reduce environmental pollution.

Description

technical field [0001] The invention relates to a water quality adjustment method in wastewater treatment, in particular to a water quality adjustment method for stone processing wastewater. Background technique [0002] In recent years, with the development and growth of the stone industry, the waste generated by it, such as slag and gravel, has also increased, which has brought a great impact on people's living environment, and some even caused serious pollution and destroy. In order to achieve the ideal effect of the stone surface in the production process, some enterprises use a large amount of domestic water, which has caused a serious waste of water resources on the earth; some enterprises have begun to treat and recycle waste water in order to save domestic water. [0003] At present, the wastewater treatment methods frequently used in the stone industry, such as digging multiple pools to filter and settle one by one, using multiple iron tanks to settle one by one, a...
