The main process block of the integrated treatment system of HDC
waste water used in the line is a high-efficiency reaction and a
high-efficiency flow filter: The high-efficiency reactor, as a
reaction unit of the wastewater to be treated and the medicament,
is equipped with a dry powder dosing machine, and is equipped with
high-speed stirring at the same time, so that the desulfurization
wastewater can fully react with the integrated high-efficiency
adsorption flocculant. At this stage, most of the heavy metal ions,
sulfur ions, fluoride ions and other control indicators through the
role of chemicals, from dissolved to suspended, and quickly
adsorbed flocculation to form primary alum. The high-efficiency
cyclone clarifier is responsible for separating suspended solid
matter and colloidal or suspended pollutants released from the
water. Through systemic circulation and filtration bed technology
of the equipment, the primary alum flowers are continuously
flocculated to form alum flowers with faster sedimentation rate.
Thirdly, through the shallow sedimentation technology and
centrifugal separation technology, the alum is deposited
continuously, forming a high concentration of sludge underflow. At
the same time, the overflow clean water can be guaranteed to meet
the discharge requirements.Beijing Huade Wastewater Treatment System uses an integrated water
purificant, which can remove suspended solid matter, heavy metal
ions, fluorides, sulfides and macromolecular organic pollutants
through adsorption, complexation and flocculation. The reaction
speed is fast, the dosage of medicament is small, and there is no
secondary pollution. Compared with the traditional triplet process,
the application of HDC integrated treatment system has significant
advantages.
A. short process, small operating intensity, simple equipment
composition, can completely replace the traditional (waste water
flow station + triplet + decanter + decanter + decanter) system,
The effluent index and anti-fluctuating capacity are much better
than the traditional waste water treatment, and the tolerance of
influent suspended solid matter can reach up to 12%. The
distributed water treatment system is changed into the integrated
and assemblable water treatment system, which is easy to install
and construct, and is convenient to expand and enlarge the system.
C. Only adding a single agent can solve the problem of excessive
discharge of many pollutants in desulfurization wastewater, with
simple operation, strong ability to resist water quality
fluctuations, and small agent dosage, and the dosage of
conventional wastewater agent is only 100-300g / m. D. agent plays
a certain role in conditioning the sludges, increasing its
hydrophobism, can be directly into the vacuum belt dewater machine
for dewater operations, without separate supporting desliming
equipment. After revamping and operation, the desulfurization waste
water treatment capacity of Laibin Power Plant reaches 15t / h
stably, and the effluent indexes meet the discharge criteria of
desulfurization waste water of coal-fired power plant. The
equipment runs reliably, and the system can realize unattended
automatic operation. The difficult problem of desulphurization
waste water treatment in power plant is solved, and the operation
of productive technology is ensured.
