The invention relates to the improvement of a method for treating polymer-containing sewage of an oil field. The method is characterized in that microorganisms are formed by mixing bacillus cereuses, bacillus megateria, bacillus subtilis, candida lipolytica, bacillus brevis and pseudomonas fluorescens; after microorganism aerobic degradation, post filter treatment is carried out; obligate microorganisms are used for degrading oil and organic pollutants bonded on polymers, thereby improving the separability of surplus inorganic substances and polymer-containing substances; and meanwhile, the degradation of the oil and the organic pollutants creates a condition for subsequently prolonging the filter period of a filter material. The invention has the advantages of simple process, simplified flows, convenient running and management, good treatment effect, low treatment and running cost (0.65-0.7yuen / ton of water, which is 2 / 3 of that of conventional treatment), no need of adding any drug,no treatment secondary pollution and stable treatment effect, can guarantee that treated yield water can stably reach 5.5.2, has small sludge quantity and does not need a sludge treatment system, thereby solving the treatment problem of polymer-containing sewage of an oil field.

The invention discloses a novel dehydration method of calcium hydrogen phosphate product slurry. The method includes the following 4 steps: material distribution, first dehydration, second material distribution and second dehydration. The four steps are mainly carried out through an adhesive tape filter, which consists of a vacuum filtration box, an adhesive tape located above the vacuum filtration box and an adhesive tape machine controlling the adhesive tape rotation. Specifically, the adhesive tape thickness is greater than or equal to 40mm, the adhesive tape moving speed is 0.08-0.1m / s; the vacuum gas pumping amount of the vacuum filtration box is set at 7-8m<3> / m<2>, the vacuum degree is 0.06MPa, and the total length of the vacuum filtration box is 6-7m. The method provided by the invention has the advantages of good dehydration effect, simple operation, high automation performance, low production and running cost, and small safety risk, etc., thus being suitable for popularization and application.

A quartz sand purification system without water washing process of the present invention comprises a pickling device, a filtering device, a drying device and a finishing device, and the quartz sand material is sequentially transferred between the four; the drying device includes a fluidized bed dryer, The material inlet of the fluidized bed dryer is connected to the silo, and the material outlet is connected to the collection bin; the hot air inlet of the fluidized bed dryer is connected to a heating furnace, a blower and an air filter in sequence, and the hot air outlet is connected to a cooler through a pipeline in sequence , a multi-stage dust removal device, a multi-stage water absorption device and an acid mist absorption tower, the gas outlet of the acid mist absorption tower is connected to the atmosphere. The present invention can satisfy the deacidification process of water washing, not only saves a large amount of environmental protection and production investment, but also saves water and wastewater treatment operation costs, reduces production costs, and can further play a role in deacidification during the fluidized bed drying process. mixed effect.

The invention relates to a system and a method of synergistic treatment of household garbage and energy resource comprehensive utilization with a rotary cement kiln. The system includes a garbage metering and storing system, a grate furnace, a rotary kiln, a decomposition furnace, a pre-heater, a boiler water steam comprehensive utilization system, a grate cooler, a kiln head dust collector, an odor treatment system and a leachate treatment system. Household garbage is fermented to reduce the moisture to about 20% and then is fed into the grate furnace by a grab bucket for being combusted, and generated flue gas is fed into the decomposition furnace through a kiln tail smoke chamber. In the decomposition furnace, harmful substances in the gas are decomposed under a high-temperature environment, wherein the waste ash in the flue gas is fed into the rotary kiln with the materials in the decomposition furnace together and then is calcined to form clinker. Meanwhile, flue gas in the kiln is subjected to equivalent replacement in the kiln tail smoke chamber, wherein the flue gas, after passing through a boiler, is discharged into the kiln head dust collector to collecting dust and then is emitted into air through a chimney. The system is free of a garbage sorting facility. The method is simplified in processes and is reduced in cost, is reduced in operation cost of garbage treatment, so that the method and the system can improve the problem that there is no garbage sorting in China at present.
