摘要： A method may add whey to high calcium papermaking industrial wastewater blended and pre-acidification treatment to promote anaerobic reaction and inhibit calcification. The method includes, before anaerobic treatment of papermaking wastewater, mixing whey wastewater with the papermaking wastewater. The method also includes pre-treating the papermaking wastewater by acidification to stabilize the papermaking wastewater prior to entering an anaerobic reaction system.

摘要： An efficient electrolysis system for sodium chlorate production may include round or oval cells, reactors, a product pump transfer, a buffer tank, a circulation pump, and explosive clad plate, all of which are connected by way of pipelines. Inlet and the outlet of each cell are separately connected with the reactor via titanium pipes, allowing the electrolyte to recirculate naturally between the cells and the reactors. The outlet of every cell is conical while each reactor includes a standard electrolytic unit with three to eight cells. The electrolytic units are modularly identical and symmetrically linked to the buffer tank. Within each unit, adjacent cells are connected with the explosive clad plates. The buffer tank may be divided into two parts—part A and part B—with part A connecting with the overflow port of the reactor via pipeline, and the part B connecting with the reactor via the circulation pump. Part B is equipped with a refined brine feed pipe on the top, the bottom of part A connects with a product transfer pump (3) via pipeline.

摘要： The disclosure provides a method for preparing an amphiphilic lignin nanomaterial based on pulping black liquor, an amphiphilic lignin nanomaterial, and an oil sludge detergent. In the disclosure, physical treatments such as ball milling and high-pressure jet homogenization treatment are conducted on alkali lignin at the early stage to adjust the molecular weight and size of alkali lignin and thus to give alkali lignin nanoparticles with uniform particle sizes; and on this basis, a chemical treatment such as alkylation grafting modification is conducted to give amphiphilic lignin nanoparticles with both hydrophilicity and lipophilicity. Due to the nano-size effect, the amphiphilic lignin nanomaterial has a significantly-increased specific surface area (SSA) and effectively-improved surface properties, which can reduce the oil-water interfacial tension, and emulsify the crude oil and peel off the crude oil from the surface of rock particles, so as to achieve the purpose of oil-solid separation.

摘要： A high-purity chlorine dioxide gas may use hydrogen peroxide as a reducing agent and may use horizontal generator, evaporation crystallizer, dryer and other devices to produce chlorine dioxide gas (product) and sodium sulfate (by-product). Compared to the conventional chlorine dioxide preparation system, the chlorine dioxide reaction and the sodium sulfate crystallization are performed in two processes. These processes are relatively separate and independent, and continuously produce chlorine dioxide gas with high purity and low moisture content while the by-product salt cake is evaporated, crystallized, filtered and dried, thereby producing sodium sulfate, without generating solid and liquid waste.

摘要： A system for the integral chlorine dioxide production with relatively independent sodium chlorate electrolytic production and chlorine dioxide production is provided. The system may feed electrolyte solution into a solid-liquid filter, filtering out the crystal and eliminating sodium chloride and sodium dichromate. The sodium chlorate crystal may be fed into a chlorine dioxide generator after dissolving, while sodium chloride and sodium dichromate solution separately return to electrolyzer for electrolysis process. Sodium chloride may be constantly formed as a by-product in the chlorine dioxide production unit, and solution containing the sodium chloride is withdrawn from the generator and, after filtration, washing and dissolution, recycled back to sodium chlorate production unit. This way, there is no need of sodium chloride make-up.
